Who we want

We’re assembling a top-tier founding team and we’re looking for the brightest engineers with startup experience and a founder mindset.

If you’re looking for a comfortable job with well-defined tasks, this isn’t it. If you want to build and ship at breakneck speed, own massive impact, and shape a world-class product from day one, let’s talk.

You need

  • Startup experience and founder mindset – You’ve built things from scratch, owned projects end-to-end, and think like an entrepreneur. You’re not just here to build a product; you’re here to help build the company. We don’t work in silos — it’s crucial to understand our domain, our customers’ problems, and how we solve them. You think beyond code and care about the bigger picture.

  • Speed – You turn ideas into shipped features in days, not weeks, and thrive in a fast-moving environment.

  • Curiosity and continuous learning – You have a deep curiosity about how things work and how they could work better. You’re not just focused on technology but also on business, customers, and what makes startups succeed. You see every challenge as an opportunity to learn, grow, and push beyond what you already know.

  • Boldness to step outside your comfort zone – You take on challenges that stretch your abilities, experiment without hesitation, and embrace the unknown.

  • Full-stack mastery with modern JavaScript/TypeScript stack – You can own entire features from backend to frontend.

  • Track record of maintaining large codebases with growing teams – You write scalable, maintainable code and have experience with long-term tech decisions.

  • Experience with Vue.js or React and Node.js – You can build and ship high-quality web applications.

  • Excellent taste in product and UI design – You have a strong sense of what makes a great user experience and care about the details.

  • Strong PostgreSQL knowledge – You write efficient queries and know how to optimize performance.

  • Comfortable talking to customers – You’re not afraid to jump on a call, understand their needs, and get direct feedback.

  • Genuine passion for AI tools of the future – You’ve likely built something with LLMs just for fun or to solve a real problem.

Bonus points

We don’t expect you to be a unicorn but deeper experience in some of these areas would be highly appreciated:

  • Optimizing complex SQL queries and building realtime analytics/reporting pipelines

  • Building scalable distributed task queues with Redis or similar tools

  • DevOps experience with Google Cloud Platform (we use e.g. Github Actions and Cloud Run)

  • RAG pipelines, embeddings, vector databases, full-text search

  • Custom UI design systems/components

  • Realtime collaborative features using Websockets, tRPC, YJS etc.

How we work

  • Ship end-to-end: You own the problem, not just a layer in the stack

  • High autonomy: You'll have the context and trust to make big decisions

  • Small team, high impact: No bureaucracy, just high-speed and high-quality shipping

  • Speed first: We try things out instead of endless planning
