Middesk | Full-time | SF / NYC | Hybrid | middesk.com

Middesk helps companies figure out who’s actually behind a business. Banks, fintechs, and platforms rely on us to get that answer fast and accurate before they issue a card, fund a merchant, or open an account.

We pull data from hundreds of government agencies, resolve it into a single view of a business, and serve it through an API. Business verification is becoming core infrastructure connecting businesses, banks, and governments, and that’s what we’re building. And our engineers build with AI every day. Earlier this year, agents helped us refactor our entire data pipeline.

Middesk is a Series B company backed by Sequoia and Accel, came out of YC, and was recently named to Forbes’ Fintech 50. We’re looking for folks who like getting close to customers and turning that context into product decisions.

ArtCraft | Senior Engineers | SF (Onsite) / Atlanta (Onsite) | $150-$250k + Equity | https://getartcraft.com

Those fucking rent-seeking hyperscalers took the internet away from you, and we’re going to give it back to you and to everyone.

Web 1.0 was great - we had IRC, file sharing, third party chat clients. There were personal websites, forums. Flash was a format kids could use. Everything supported embedding and uploading. Websites actually had APIs and RSS. File sharing, FTP, MP3s, discs, owned media.

Broadband brought our parents and grandparents online, but the shift to the non-technical majority created an opportunity to grossly oversimplify everything. Everything dumbed down into a pre-packaged product. Startups began turning their offerings into walled gardens. Platforms took precedence over protocols. APIs and access and data export went away. And then the rent-seeking began. The era of ownership ended.

Corporate Memphis. Jesus Christ.

We’ve rallied a massive community to build MIT/Apache-licensed alternatives to Adobe, Microsoft Office, Google Workspace, Autodesk, SolidWorks, Slack, Discord, Unreal Engine, OpenRouter, RunPod, and more. The goal is full feature parity, with code anyone can own, inspect, modify, and build on.

We’re digesting second-class apps and platforms into first-class applications, libraries, and APIs with full MCP support. We’re distilling out the good parts, and we’re building the connective tissue that draws them together.

100% of the internet is going to be open source soon, and we’re going to force it open. Loudly.

We have eight figures in run rate revenue, over 20M app downloads and growing. Our community is the best part, and it’s energetic like a wildfire. Everyone resonates with our mission.

We’re missionaries, not mercenaries. We are going to slay the incumbents by being better. Our motto is Google’s old motto - “Don't be evil (tm)”.

We’re a tiny team looking for strong engineers to own major parts of the product: desktop apps, lots of completely open source backend infrastructure, agent workflows, agentic app factories. Stack: Rust, a sprinkle of TypeScript/React, egui, Tauri, MySQL/Postgres, Redis, Elasticsearch, Kubernetes. Lots and lots of Rust. We’re systems engineers by trade, but we like to vibe code Rust. Did I say Rust? Rust. Rust Rust Rust. Maybe that's a filter.

You have to be self-directed and independent. If you want to open source Salesforce with half your time, do it! If you want to work on Solidworks 3D printing applications, great! Writing music apps and DAWs? Go for it! Custom Discord/Slack clients for our custom, completely open source chat API and platform? Hell yeah. Our organization is flat, and we're going to go after everybody and everything.

Everything you build here will be open source. We have no private repos.

We can reclaim the internet. That’s our mission.

Want to know more about us? Look up “Adobe ArtCraft” on YouTube / TikTok / your platform of choice.

If this resonates with you, email hn@storyteller.ai with your Github, a little about yourself and something you’ve built. Write the sentence, “don’t take my RAM, Sam!” so we know you’re one of the good guys.

eventfirst | Senior Full-Stack Engineer | Berlin, Germany | REMOTE (CET) | Full-time | eventfirst.com

We are applying AI to organize corporate events.

We are looking for a senior engineer with at least ten years of full stack experience, a strong focus on product and UX, and some experience building an AI chat based product.

Our tech stack is Typescript, React, Next.js and Tailwind. On the backend we use Drizzle with Neon, deployed and monitored via Vercel. Agents and background jobs are executed via trigger.dev. This gives us a killer DX because the entire tech stack supports preview branching. This allows coding agents to work in parallel on different features and verify their work independently very close to what will run in prod. CI is fast (2-3 min) and coverage is good enough to deploy to prod many times per day.

Please note that we are working remotely in the CET timezone. Having some remote experience is a plus.

We have pre-seed funding from a major US VC and are experienced founders. You’ll be working alongside the founders (ex-Apple, ex-Airbnb, ex-Tulip, ex-Tourlane) and will have a chance to shape the company, product and of course the engineering culture.
