## Job description

**Opportunity**

- ZeitMind is an autonomous data engineer for mid-market businesses. Agents and people work the same company data: ingest, pipeline, clean, analyse, build operational apps
- we are growing fast and will be onboarding multiple enterprise customers a week. The backend isn't ready yet, your impact will decide the speed at which we can grow
- load growth is compounding: more customers, multiple users per customer, many agent interactions per user and multiple agent artifacts (data pipelines, schedules, analyses) coming out of the interactions
- you own the platform

**What you'll do**

- scale a multi-tenant Postgres under unpredictable load: query and I/O optimisation, read/write separation, horizontal scaling
- make agent-driven workloads survivable: one user can spin up 30 table syncs, some running hours, while others query large sources
- manage the sandbox layer: Docker containers where agents run queries and reverse-engineer files, with compute and memory budgets
- own connectivity into customer networks: SOCKS5 over WebSockets, authentication, routing
- scope the architecture and build it

**What we're looking for**

- staff or principal level, still hands-on, writing production code
- built and scaled multi-tenant data platforms in a B2B startup or platform company before
- deep Postgres or database knowledge: query plans, locking, I/O, caching, replication, sharding
- understands startup pace and ownership without specs
- pragmatic over ideal, wants to build foundations right without overengineering
- strong TypeScript
- English C1, German a plus

**Nice to have**

- experience at a data platform or warehouse company (Snowflake, Databricks, Cloudflare or similar)
- networking depth: proxies, VPN, routing

**Location**

- preferred: Munich, on-site. We support relocation within Europe
- already in London? We can make that work. We have people here and are opening a small office, and we'd expect regular Munich travel. In-person culture is important to us

**Tech stack**

- TypeScript end to end. Bun, tRPC, Postgres, Supabase. React frontend (Mantine, TanStack Query). Docker, job/process management, VPN/routing, agentic frameworks
