<section id="the-opportunity-section"><h2 id="the-opportunity" role="presentation"> <a href="#"></a><span role="heading" aria-level="2">The Opportunity</span> </h2> <p>Logfire stores billions of telemetry records and serves them back with sub-second query latency. The engine that makes that possible is <code>fusionfire</code> — a disaggregated analytical database we built in Rust on <a href="https://github.com/apache/datafusion">Apache DataFusion</a> and <a href="https://arrow.apache.org/">Apache Arrow</a>.</p> <p>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.</p> </section>
