About the Role
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 pipeline, schedules, analyses) coming out of the interactions. You own the platform.
Responsibilities
- Scale a multi-tenant Postgres under unpredictable load, including query and I/O optimization, read/write separation, and horizontal scaling.
- Make agent-driven workloads survivable, handling scenarios where one user can spin up numerous table syncs with varying runtimes.
- Manage the sandbox layer, which includes Docker containers for agent execution with compute and memory budgets.
- Own connectivity into customer networks, covering SOCKS5 over WebSockets, authentication, and routing.
- Scope the architecture and build it.
Requirements
- Staff or principal level, still hands-on, writing production code.
- Proven experience building and scaling multi-tenant data platforms in a B2B startup or platform company.
- Deep Postgres or database knowledge, including query plans, locking, I/O, caching, replication, and sharding.
- Understanding of startup pace and ownership without specifications.
- Pragmatic approach, focusing on building solid foundations without overengineering.
- Strong TypeScript skills.
- English C1 proficiency.
- German language skills are a plus.
- Experience at a data platform or warehouse company (e.g., Snowflake, Databricks, Cloudflare).
- Networking depth, including proxies, VPN, and routing.
