Job description
This is a genuine founding engineer opportunity.
You'll work directly with the founders and own major parts of the product from day one - helping define architecture, product decisions, and how AI should actually show up inside critical workflows.
Two major challenges:
- AI-native workflow software, not chatbot theatre
The goal isn't another chat interface on top of documents.
It's building software where AI operates through automation, background processes, alerts, workflows, and delegated execution - knowing when to act silently, when to recommend, and when humans should stay in control.
- Extending agent systems all the way to the frontend
Agent infrastructure doesn't stop at backend orchestration.
You'll build frontend systems that handle streamed outputs, tool execution traces, partial renders, interruptions, and recovery flows as first-class product experiences - not UI afterthoughts.
Stack
TypeScript, Next.js, Vercel, Supabase (Postgres + vector search), modern LLM tooling, agent frameworks, observability tooling, and production-grade AI workflows.
Greenfield environment. No legacy systems.
Strong tooling culture with dedicated AI experimentation budget per engineer.
Requirements
- Strong full-stack engineering ability with excellent product instincts
- You think from user pain ? product decision ? measurable outcome
- Comfortable speaking with customers and understanding operational workflows
- Fast execution without sacrificing reliability
- Strong ownership mindset and comfort operating in ambiguity
- You can prototype quickly, test assumptions, and improve based on real usage
- Bonus points for startup experience, strong open-source work, AI systems, document understanding, or systems that replaced manual operational work
Level is flexible - they care more about exceptional people than rigid seniority labels.
English-speaking environment. German is helpful but not required.
Benefits & conditions

- Immediate production impact on high-value real-world problems
- Strong equity package (0.5%-1.5%)
