Senior Software Engineer, Database (SmithDB)

Job summary

Responsibilities

We're a fast-moving team looking for a systems / database engineer to help design, optimize, and harden our system. Within 6 months, we've gone from idea to production system but there is still lots to build and optimize.

• Engineer performant Rust code for ingestion and query execution
• Optimize for cost and speed, heavily utilizing memory and CPU profiling
• Integrate tightly with cloud object stores (S3/GCS/Azure Blob)
• Deploy our distributed database services on Kubernetes (multi-tenant, high throughput, low latency)
• Contribute to observability for the storage engine itself (metrics, tracing, debug tooling)

What they're looking for

• 5+ years in systems/database engineering with strong experience in a systems programming language (Rust, C++). Rust strongly preferred, as it is the language we use.
• Knowledge of database internals is a plus: query engines, storage systems, indexing, and compaction
• Proficiency in systems performance analysis: memory allocation, CPU hotspots, lock contention, async runtimes.
• Familiarity with similar query execution engines is a plus
• Experience with Kubernetes, distributed systems, and cloud object storage is a plus.
