Job summary
Responsibilities
We're looking for a hands-on Engineering Manager to lead the SmithDB team. This is not a pure people-management role. You'll write production code, review PRs at the systems level, make architectural calls, and be in the weeds alongside your engineers.
- Write and review production Rust code across ingestion, query execution, and storage layers
- Lead architectural decisions on storage format, compaction, indexing, and query planning
- Drive performance investigations using memory and CPU profiling tools; own the path from profiling to shipped fix
- Design and harden the distributed deployment of SmithDB services on Kubernetes (multi-tenant, high-throughput, low-latency)
- Contribute to cloud object store integrations (S3, GCS, Azure Blob) and set the standard for how SmithDB manages data at rest and in flight
What they're looking for
- 7+ years in systems or database engineering, with at least 2 years in a technical lead or engineering management role
- Production Rust experience — you can write it, review it, and have opinions on how to structure it at scale
- Deep understanding of database or storage engine internals: query execution, storage layouts, indexing, compaction
- Proficiency in systems performance analysis: memory allocators, CPU hotspots, lock contention, async runtimes (Tokio)
- Experience deploying and operating distributed services on Kubernetes in a production, multi-tenant environment
