As a senior engineer on the database team you will shape the architecture build and launch critical database capabilities that keep our services fast reliable and efficient at global scale. You will report to the Technical Director for Storage.

You will:

• Design and implement new engine featuresindexing storage formats WAL and replication protocols sharding and query-planner enhancementsthat push latency throughput and availability boundaries.
• Evolve the control planeto deliver elastic scaling autonomous healing and zero-downtime schema or tenant moves across global regions.
• Profile and optimizecritical code paths using kernel-level tracing and advanced performance tooling; drive systematic tail-latency reductions.
• Establish engineering best practicesby 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.
