The Opportunity

Logfire stores billions of telemetry records and serves them back with sub-second query latency. The engine that makes that possible is fusionfire — a disaggregated analytical database we built in Rust on Apache DataFusion and Apache Arrow.

The data store is one of the largest and most technically demanding parts of our engineering org — roughly a quarter of our engineers work on it — and we're looking for a Principal Engineer to help lead its next phase. You'll work at the level of query planning, columnar storage, distributed execution, and resource scheduling: the parts of the system where one good decision is worth orders of magnitude.
