## 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
