Senior Software Engineer

• Work across the whole stack: React Native, React, TypeScript, Python, FastAPI, PostgreSQL, OpenTofu/Terraform, GCP and AWS.

• Write specs precise enough for a teammate or an AI agent to implement.

• Treat product decisions as your own and push back when you disagree.

• Automate whatever can be automated, from internal tools to ops, QA, and deploys.

• Hold several tasks at once while AI does the coding and you do the thinking and review.

• We write all our code with AI; by hand is too slow.

• We ship several big features every week or two.

• Humans design and architect, AI writes the rest.

• Every review needs human approval.

• You are a systems thinker.

• You've built and architected complex systems and owned non-trivial ones end to end.

• You can present an idea, defend it, change your mind on good input, and write it down clearly.

• You're a generalist who'll learn whatever is needed; your current stack doesn't have to match ours.

• You're happy coding with AI by default.

• You're fine with no PM, no assigned architect, and no manager turning problems into tickets.

• You build what's missing instead of waiting for it.

• This is not a 9-to-6 job: overtime is regular, and the workload can spike with little warning.

• We're a small team, with no large engineering org or platform team behind you.

• Specs and priorities shift constantly.

• We give above-average equity because we want you to act like an owner, not an employee waiting for direction.

• We move fast

• Small, highly motivated team with real ownership

• 3 days a week in our office.

• Our working language is English.

• One month a year, you can work from anywhere.

• Competitive salary.

• Equity above the German startup average, on purpose. We want engineers who are owners.

• Up to €2,000/month AI budget.

• Intro call (~30 minutes). A quick read on both sides to see if it's worth continuing.

• CTO interview (~1 hour). Can get technical, no live coding. We want to see how you think, design, and argue.

• Test day. You spend half a day in the office working with the team on a real task, the kind of work you'd actually do here.

• Final interview with the CEO.

• Offer.
