Staff Backend Engineer, Platform

Munich, London
Full-time
Visa Sponsorship

About the role

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
