## 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, Ge
