Figma | Security Engineer | Remote or Hybrid (SF, NYC, Seattle) | https://figma.com | Full-Time, $149-350k + Equity

Figma makes the tools that modern companies use to design apps. And because of that highly sensitive data, security is extremely important to get right. (If the next iPhone were designed using Figma and a breach leaked it... yeah, you get the point.)

Anyway, I am on the security team over here at Figma and reminding the excellent HN folks that we're hiring. I'm primarily working on AI and Snowflake Security currently, but I've hopped around over the past year. You likely will too!

We are a bit of a weird hybrid hiring-wise though. We need engineers with a security background than can _also_ write production-grade software.

(If you are a regular SWE then please check out Figma Careers page for a better role to apply for. There are many open roles, though keep in mind that Figma tends to only hire at the "Senior" bar and up. Not very many junior folks here.)

This is the link for my team if you're interested! Feel free to ping me at my email on my profile if you have questions. Cheers!

Layer | Founding Eng | San Francisco In-Person Only | Full-Time

Layer is looking for engineers who believe in empowering American SMBs and want to be a part of high-ownership team. If you want to tackle serious technical challenges across system design, scale, and data management and you care about being on a team that has high expectations for our product and ourselves, get in touch with me at daniel [at] layerfi.com

We’re building SMB accounting software API-first so that it can be integrated directly into software platforms where business owners already work. Our customers are vertical software platforms in the vein of Toast, MindBody or Housecall Pro that help small business owners start, run and scale their business with workflows and financial products. We help them serve their customers who are stuck exporting all their data out of these systems into CSVs and importing it back into other accounting software.

Integrating with our accounting APIs gives business owners automation & accounting workflows directly within their core software while the software platforms get to solve one their customers’ biggest pain points: worrying about bookkeeping & finances.

If this sounds like you shoot me an email and tell me why this is a good fit for you - I'll respond!

Corgi (YC 24) | Golang/Full-Stack Engineer | In-Office | SF | Full-Time

We're building an AI-first insurance company from scratch. Not just adding AI to existing processes - we're automating the entire insurance value chain. Think of it as rebuilding the insurance stack with code instead of paperwork.

I'm part of the engineering team at Corgi. We need someone who can write solid Go code and isn't afraid to jump into React/TypeScript when needed. Our stack is cloud-native (AWS/GCP/DO), heavily containerized, and we're pushing hard on AI/ML integration.

Requirements: - 1-2 years of Go in production - Frontend experience with React/TypeScript - Cloud platform experience - Docker and database skills - Shipped real products to real users

This is an early-stage role (we're YC-backed) so you'll own features completely, from backend to frontend. We're in the office seven days a week - this isn't a role for those seeking work-life balance, but perfect if you want to build something massive from the ground up.

Note: We're looking for builders who ship. If you prefer perfect code over working products, this probably isn't the right fit.

Compensation: Competitive salary + equity

Project Healthy Minds (startupy mental health nonprofit) | Full-time | NYC | 5d/week in-office

We're looking for someone to lead our small-but-growing engineering team at our Hudson Yards office. There are about 10 full-timers in the office, but engineering and product design are all contractors / moving to full-time this year. I'm leading product and the search for this role.

This is a unique opportunity – we're building a comprehensive dataset of mental health services and outcomes while prioritizing user privacy. As a nonprofit, we have no incentive to monetize user data. Instead, we're focused on two things: 1) helping people find care across the full treatment spectrum through our screening process (as developed with our clinical advisory committee), and 2) collecting anonymized outcome data to understand what actually works in mental healthcare - something that surprisingly doesn't exist yet at scale.

Our goal is to simultaneously solve the discovery problem for people seeking care while building the dataset needed to improve mental healthcare quality and accessibility. Think of it as a privacy-first infrastructure layer for mental health services.

AngelList | Senior Software Engineers, Engineering Lead, Product Designer, Senior Data Engineer, etc | Full-time | Hybrid in San Francisco

AngelList's mission is to accelerate innovation by providing startups and investors with the tools they need to succeed. We have the world’s largest early-stage venture portfolio with $17B+ assets under management and $124B+ on our platform, delivering capital to over 12,000 startups. We work with some of the best emerging fund managers to ensure every deserving startup has access to capital.

I was hired into the role from one of these HN threads last summer. One of the things that attracted me most was the density of former founders and aspiring entrepreneurs on the team.

I'm the hiring manager for two senior roles on our Funds Engineering team. We’re building the data layer that powers our general ledger. We work on some of the most interesting datasets out there: We model capital flows in the venture ecosystem to understand where value accrues and, ultimately, which investors and founders win or lose.

I'd be happy to talk about these roles, about any open role we have at AngelList (https://www.angellist.com/careers#open-positions), or any questions you might about working here.

Blueberry Pediatrics | Full-stack Senior or Staff Engineer | REMOTE (US-only)

American healthcare is seldom affordable, accessible, or high-quality. We are fixing this for pediatrics. Blueberry is the most affordable option amongst our competitors. We practice the highest quality pediatric telemedicine, as evidenced by our exclusive hiring of board-certified pediatricians and the usage of at-home medical kits. And, we’re accessible 24 hours a day.

Our success is shown in the lives we save, the costs we save our insurers, and our exploding B2B and D2C business.

As you can imagine, pulling off affordable high-quality healthcare is a challenge. It requires a lot of engineering ingenuity, a C-suite aligned with positive patient outcomes above short-term profits, and a great product team.

We use Django and Hotwire Turbo (an HTMX-like framework). Experience in these technologies helps, but what’s more important is general full-stack knowledge, curiosity, and a strong work ethic.

Supabase.io | Customer Solution Architect / Engineer | Full-time | REMOTE (US)

I am one of the first SAs at Supabase and our role is to help onboard, optimise and advise on all parts of the Supabase platform.

No need to be a postgres expert, you will be working with customers of all sizes and using all aspects of the platform. One minute you might be onboarding an engineering team and the next you might be helping an existing customer with their scaling plans for the next 6 months or triaging a bug/feature request to ensure the Product team understands the context and priority. Technical skills are vital but "self-starter" is equally key. Being able to determine what cases need your attention compared to those that need escalating to Product or Engineering. Excellent comms skills (internal and external) certainly help, too!

I wanted to work at Supabase because of its open source nature and I want to stay here because of its fully remote, autonomous nature. Trust first in the work we do and it is easy to grab a member of the team to solve a problem async.

Job post and application details are here: https://jobs.ashbyhq.com/supabase/d5573afa-636c-4219-832f-38...

We're searching for a full-time engineer to join our founding team. Our device and prototypes are partly mechanical, electrical and software so we'll need someone who can wear multiple hats but is comfortable primarily in the mechanical domain as we execute on early clinical and pre-clinical studies.

Experience with rapid prototyping using 3D printing, CAD and bench models is a must. Experience of medical device development within a quality management system and developing pre-clinical models is highly valued. Bonus points for electrical engineering experience, programming experience (Python/Matlab) and a passion for auditory science. More than anything, we're looking for someone who will be highly motivated to help bring a complex but life changing device to patients.

We're a small team formed out of Stanford and backed by YC (W21), based out of Fogarty Innovation in Mountain View. The role is primarily in-person with very occasional travel to study sites and with some flexibility for hybrid work from time to time.

We're excited to hear from you! [email protected]

Sitch App | Engineering Lead | NYC-area HYBRID (2 days/week in Brooklyn) | Full-time | Python + Django + Flutter + Rust

Sitch is a new type of concierge dating app. We're using AI + Humans to ask you questions, get to know you, then help you find love. We're a concierge matchmaker but we don't call ourselves that and we don't charge the obscene prices that matchmakers charge.

One of our metrics is how little time you spend in the app. We're explicitly opposed to the dopamine-fueled mini-game doomswiping of 'traditional' dating apps which cynically monetizes desperation.

* We're top-tier VC funded, small team of 2 cofounders (Snapchat, Bumble) and 3 engineers, based in NYC.

* Stack is Django, OpenAI, Flutter, Rust for Chat infrastructure.

* Looking for a Sr. Eng who is an all-arounder and wants to eventually manage. Backend more important than front-end code, but if can also work on client code (or want to learn) that would be ideal.

* 2 days/week in person, in Brooklyn, and the rest remote. We strongly prefer NYC area candidates.

Timescale is continuing to grow rapidly, and we’re hiring for many roles involving distributed systems and databases.

Timescale extends PostgreSQL to handle relational data, time-series, events, real-time analytics, and vector search in a single application database. It’s built for data-heavy, mission-critical apps while retaining the familiarity and reliability of Postgres. Ideal for IoT, crypto, finance, SaaS, and more.

Database code all available on github; we don’t have any “enterprise versions”, so all our database code is available for the community for free. Currently, see more than 3 million databases running TimescaleDB a month.

That’s because our commercial focus is on our fully-managed cloud platform, so in addition to folks implementing the core database (C, Rust), we’re also heavily hiring for folks with operational cloud & database experience at scale (Kubernetes with custom k8s operators, Golang, etc), as well as folks interested in providing highly technical support, database release engineering, and building database testing infrastructure (think performance analysis, distributed database correctness testing, etc.) And product folks to support these efforts & all our users!

Juniper (YC W21) | Senior Software Engineer | Full-time | HYBRID NYC | juniperplatform.com

Juniper is working to improve the messy financial infrastructure for US Healthcare. We've built an automated end-to-end insurance billing system for recurring care, starting with Autism clinics. It’s a product that clinicians need and love.

We automate and abstract the tedious, manual, repetitive work that goes into the administrative duties of running a clinic, so that clinicians can do what they do best — providing care.

It starts with ingesting clinic data, and then create, validates, and submits claims to insurance providers across the country. If claims need corrections or appeals, most of the time we can handle those automatically or our CX and Operations team use our in-house internal tools. We also handle patient invoicing for co-pays, co-insurance, and deductibles (we never send anything to collections). We track money movement on a unified ledger and reconcile transactions with clinics' bank accounts.

There is so much more to build. If you're interested in scaling data pipelines, programmable rules engines, AI, data science, delightful products for small clinics, processing billions of dollars in money movementm or solving the unsexy problems that make this country's healthcare broken, come join us!

We are a team of ~40 with strong product market fit. You’ll be working with an engineering leadership team from AWS and Stripe to get clinicians back to work delivering care for kids.

AuthZed (W21) | Multiple Roles | Remote | Full-time | $150-270k

AuthZed Cloud is fully-managed, database-as-a-service platform built to be the foundation for authorization across product suites and oceans. At the core of AuthZed Cloud is SpiceDB, the premier open source database designed specifically to store and query access control data.

For years, there have been libraries to help developers build authorization systems, but that hasn't stopped broken access control from becoming a substantial threat to the internet. The core hypothesis behind SpiceDB is that the best foundation for authorization systems is one that is centralized rather implemented ad-hoc in each application. By providing a system that is designed to be ran by a platform team centrally for an entire organization, developers can standardize workflows, testing flows, and how to interoperate between their applications.

• Collaborate directly with a founding team behind multiple $1B+ ad products.

https://center.app | Center Pixel, Inc | Engineering | Full-time | Palo Alto, CA & Remote | 100k+ and up (we are flexible on salary since we're venture-backed and still a 4-person team)

We build web3 developer tools and are most focused on solving the "schlep" types of problems that every team ends up building in house but shouldn't have to.

Building stuff in crypto today is really hard. Imagine if you wanted to put up a personal website and all you had to do was start by breaking ground to build a data center. Your personal page probably would not be that good, would it? Small teams can only focus on so many things; we want them to use center so they can focus on the details that truly matter and make products beautiful.

We want to eliminate all of these annoying, cumbersome, expensive problems that devs face so that they can build incredible user experiences that help people flourish and rise to the level of their ambition, without having to think about if their nodes are online or if their indexer is missing any data.

We started about 3 years ago and have finally started to find product market fit. We're looking to scale the engineering team so that we can finally bring our products to market.

Our investors include Founders Fund, Thrive Capital, SV Angel, @balajis, and many more incredible folks who have taken a chance on us; it's been my mission for the last 3+ years to make sure that everyone involved in this venture does phenomenally well.

FetchFox.ai | Founding Engineer | Remote, US & Canada | Full-time | Competitive comp

FetchFox is looking for an exceptional engineer to join our team.

We’re making an AI powered web scraper. You can type what you want in English and it automagically handles all different site layouts and data schemas. It’s 10x easier than using CSS selectors and code, and it lets non-coders scrape also. Try it out at https://fetchfox.ai. However, if you’re applying for this job, you might like the Javascript library.

To install it, use npm:

    npm install fetchfox

    import { fox } from 'fetchfox';
    const results = await fox
      .init('https://news.ycombinator.com/item?id=42575537')
      .extract({ company: 'Company name', url: 'URL of the company website' })
      .extract({ summary: 'Summarize this website in 10 words' })
      .run(null, (delta) => { console.log(delta.item) });
    console.log('Results:', results);

Our compensation is competitive. Our cash compensation is similar to YC founding engineer roles, but our equity compensation is unique. We offer at around an order of magnitude (10x) more than comparable companies. You can read more about this on our site: https://fetchfox.ai/a/founding-engineer-compensation

Our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications. We want devs to stop worrying about auth and focus on building something awesome.

* a full featured free-as-in-beer version that makes the sales cycle easier; prospects often come in having prototyped an integration already

We are profitable but raised a round recently to accelerate our growth (more on that here: https://fusionauth.io/blog/fusionauth-funding ).

PGL Esports – Esportal | C++ developer for Windows Anti-Cheat | Full-time | Remote or Bucharest | https://esportal.com

Esportal is a competitive platform for major eSports titles powered by PGL Esports (PGL Majors rings a bell?). Our in-house and from-scratch built Anti-Cheat is currently focusing on Counter-Strike 2 @ Windows 10+11 x64. We’re looking for a passionate C++ developer who loves crunching lines of code. We have many ideas that want to be implemented by you.

Who you are: You’re comfortable with coding. You know modern C++. You likely spent 5+ years as a (hobby?) programmer and have made a lot of mistakes and learned from those. You survived nights in front of the holy Visual Studio debugger on Windows. You used Git and merge workflows. You were annoyed by linker errors and had victories over clang or MSVC. You know what a mutex is and think in terms of CPU slices. You favor native over Electron. You secretly dream at night to have hair like Bjarne.

What you maybe did: You’ve built your own home automation? Your own game? Your own container implementation? Your own CI? Your own OS? Your own programming language? We want you!

What you will be doing: You will implement code according to specification (you can influence those of course), work on our backlog and go on bug hunting sessions with a debugger. You will be working together with us and will not shy away from asking us questions proactively by talking/writing in fluent English. You will be enjoying cheat vendors catching up to us and playing the cat and mouse game with them.

What we offer: Small dedicated remote-first and open-minded team. Well-architectured code base originated in 2022 using C++23. Your code will partially run in Windows kernel mode. We don’t have scheduled meetings. We talk on the spot and are always available for help. We don’t care about your working hours if you are available during UTC+2 in the warmup period of some months.

Ready for a short interview process? Talk directly to our team. Send an email to [email protected] and mention HackerNews to get fast-tracked.
