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...

Do you care about contributing to open-source, and appreciate a good challenge? We do too! :)

Open-source

We are a team of veteran open-source developers, working on educational and community-based projects in an open-first environment – and we are looking for new members. By joining us, you will work full-time on open-source, pushing your changes to free software projects upstream through pull requests, contributing features, documentation, or help on public forums.

We care deeply about contributing our work upstream. You will see the results of your work reused and recognized across the educational community, increasing access to quality education for everyone, everywhere.

Remote-first

Unlike companies who reluctantly started to accept remote workers recently, we have embraced it from day 1. For the past 7 years, we have based and refined our way of working around remote-friendly workflows, from the ground up. No day-long video meetings, mandatory work hours, or risk of being forced back into an office one day -- as long as you have a good internet connection, it’s none of our business when or where you work from. :)

We are all working remotely, from all continents (except Antarctica, at least so far - applicants welcome!). We use remote-friendly and timezone-agnostic workflows based on asynchronous principles and good documentation practices.

Online education

We are one of the main contributors to the Open edX project, the main open-source MOOC platform created by MIT, Harvard and many other top universities. It powers sites like edX.org, the MIT Open Learning Library, and the national online learning platform for France. We provide development and hosting for institutions like Harvard Medical School, Harvard LabXchange, Cloudera, Autodesk, and several governments. We are not affiliated with edX.org, but we contribute and work with them on various projects.

Our handbook, like much of our work, is publicly viewable and you can find it at https://handbook.opencraft.com/.

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.

From a patient’s initial consultation to their final treatment delivery, we want the Wyndly experience to be a breath of fresh air for allergy sufferers – truly effective allergy relief, simply and efficiently delivered. We’ve already done this for thousands of patients, and we plan to do it for millions.

The Role

We’re looking for an ambitious organic & social media manager who is ready to jump in and own our earned channels and grow the business. We’ve grown a following across TikTok, Instagram, and YouTube. In parallel, we have a successful blog that ranks for many keywords. The foundation is laid and we’re ready for someone to level up these channels.

We’re a high growth team doubling revenue over the next year. We know that every hire will change our business so as you grow our social media and content channels you’ll work with our Head of Marketing and cofounders to define how Wyndly evolves. This role can look very different in a year.

We already get 1M/views per month across our videos and website. We want to triple this by the end of the year.

Our immediate goals are to get social media and our blog driving new visits to our website. But as this program grows, this role can lean into partnerships, content marketing, copywriting, or video. If we do our jobs well, you’ll have a hand in hiring our marketing team to take on the channels you helped launch.

Roboflow is the fastest way to use computer vision in production. We help developers give their software the sense of sight. Our end-to-end platform [1] provides tooling for image collection, annotation, dataset exploration and curation, training, and deployment.

Over 1 million engineers (including engineers from 2/3 Fortune 100 companies) build with Roboflow. We now host the largest collection of open source computer vision datasets and pre-trained models [2]. We are pushing forward the CV ecosystem with open source projects like Autodistill [3] and Supervision [4]. And we've built one of the most comprehensive resources for software engineers to learn to use computer vision with our popular blog [5] and YouTube channel [6].

We have several openings available but are primarily looking for strong technical generalists who want to help us democratize computer vision and like to wear many hats and have an outsized impact. Our engineering culture is built on a foundation of autonomy & we don't consider an engineer fully ramped until they can "choose their own loss function". At Roboflow, engineers aren't just responsible for building things but also for helping us figure out what we should build next. We're builders & problem solvers; not just coders. (For this reason we also especially love hiring past and future founders.)

We're currently hiring for full-stack engineers to help build our product, field engineers that work directly with our customers to solve their business needs with computer vision, and several technical roles on the sales team.

We just raised our Series B round, led by GV. With this round, we will continue building the open source tools, platform, and community so developers and enterprises can deploy computer vision applications to production. [7]

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.

* Manifesto Manufacturing is important. It’s the fundamental industry on which everything else is built. We take it for granted. In 1989, 35% of the entire software industry was manufacturing systems. Back then, services, hand holding, customization, and consulting were necessary to get the systems to where they are today. What was the first massive burst in productivity from technology has stagnated into incremental diminishing returns and exponentially increasing complexity. We can only continue to add complexity for so much longer until the whole system collapses. "Any intelligent fool can make things bigger and more complex. It takes a touch of genius and a lot of courage to move in the opposite direction." Manufacturing is important. We must deliver a touch of technological genius to reintroduce simplicity, efficiency, and integration.

At Pasteur Labs, we develop computing technologies that enable scientific and industrial challenges to be approached in new ways: that is, a first of its kind AI-native, developer-first platform for modeling & simulation (M&S). Our product aim is to enable in-silico playgrounds for human-machine teams experimenting and building in industrial R&D, energy security, & advanced manufacturing arenas. As a public-benefit for-profit startup, our mission is Nobel-Turing [1] technologies to advance science and society for all humankind. With venture funding and Fortune500 customers (+dozens more on the waitlist), we’re looking for ambitious, intellectually curious software engineers that can consistently contribute in non-trivial, impressive ways as we ship and scale our flagship product platform — some call it “live intelligent digital twins” and others say “cyberphysical testbeds for AGI”, while most view Pasteur Labs product catalogue as “Databricks for industrial R&D”.

--> https://pasteurlabs.ai/careers/ <-- While we don’t list requirements for degrees or years-experience, everyone needs to demonstrate high-caliber engineering and problem-solving; we’re dedicated to scientific rigor and robust engineering for complex and dynamic environments, so prove to us that you not only fit in but that you can make us better. In particular, we are seeking experienced DevOps / MLOps teammates that can build from day 1 with Go, Python, containerization, and our multiple cloud setups (Azure, Google (GCP), Oracle Cloud (OCI)), and on-prem infrastructure for mixed GPU & CPU workloads — if you've done this before with CAE simulation systems and scientific datasets, reach out and say so!

Our team is largely made of industry-hardened research-software engineering experts [2], whom thrive in interdisciplinary and fast-paced teams—from NASA to Nvidia, Deepmind to Oracle, CERN to Cerebras, SpaceX to Autodesk, the Navy, Air Force, and on. With HQ in Brooklyn NY [3], and satellite offices opening in Copenhagen + London + Vancouver in 2025, we are an internationally distributed team running remote full-time — from San Francisco to Sao Paulo to Stockholm and everywhere in-between. The full team gathers multiple times per year for 1-week Pasteur Labs “onsites”—recently in Miami, Amsterdam, Cambridge, and more.

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!

We're looking for a senior engineer to push our Phoenix LiveView app further as we scale up this year (next up is the superbowl this weekend, a lot of interesting stuff already underway).

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.

Purplefish is transforming the trillion-dollar talent industry with powerful AI agents that will fully automate most hiring processes end-to-end.

We are funded by 8VC, and Adam and I previously worked closely together to launch 145 companies at the venture studio Fractal Software out of a $650 million fund.

I'm trying to build the engineering team that I would want to join, which to me means a high emphasis on agency, purpose, technical excellence, collaboration, learning and velocity. Recently A16Z mentioned us in the state of voice AI report: https://a16z.com/ai-voice-agents-2025-update/

We're building on LiveKit's agents framework and a host of other systems. We're looking for builders - people who are willing to learn and experiment and build fast.

Additionally, we offer a work-from-home stipend to ensure your remote setup is comfortable and well-equipped.

We’re a small team of seasoned Engineers and Designers who love to build. We place an emphasis on building with high craftsmanship, scalability, and a platform first mindset.

Ardent [0] is a well-funded, early-stage startup founded by an ex-Stripe engineer and three-time founder. We're building a platform which helps users blend the creativity of generative AI with the determinism of executable code.

We want to help everyone build software, whether or not they know how to code. We aren't trying to put software engineers out of work — instead, we envision a future where AI makes it possible for everyone to build software that makes them more efficient, productive, and happier!

We raised ~$2.5M last year, and we're hiring two engineers to join the founding team. We're looking for highly motivated and talented candidates with experience working on a fully remote team, a strong interest in artificial intelligence, and alignment with our principles and way of working. [1]

Our interview process is efficient, and we don't do Leetcode or grueling all-day interview loops. We won't waste your time, we will stay in constant contact throughout, and we will get you an answer quickly.
