Responsibilities
Design and implement new engine features—indexing, storage formats, WAL and replication protocols, sharding, and query-planner enhancements—that push latency, throughput, and availability boundaries
Evolve the control plane to deliver elastic scaling, autonomous healing, and zero-downtime schema or tenant moves across global regions
Profile and optimize critical code paths using kernel-level tracing and advanced performance tooling; drive systematic tail-latency reductions
Establish engineering best practices by leading design reviews, performance benchmarks, failure drills, and post-incident retrospectives
Automate everything: develop frameworks for testing, CI/CD, rollout safety, observability, and autoscaling so that the platform operates hands-off at scale
Mentor and unblock engineers, fostering deep database craftsmanship and disseminating knowledge across Storage, Platform, and product teams
Engage with the open-source community—upstreaming patches, presenting learnings, and influencing the future of Postgres, RocksDB and related ecosystems
