Description du poste
** Opportunity
* ** Zeit Mind 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 Web Sockets, 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 over engineering
* strong Type Script
* 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
*** Type Script end to end. Bun, tRPC, Postgres, Supabase. React frontend (Mantine, Tan Stack Query). Docker, job/process management, VPN/routing, agentic frameworks
