Were on a mission to connect a billion people with optimism and civility, and looking for amazing talent to help us get there.
A career at Roblox means youll be working to shape the future of human interaction, solving unique technical challenges at scale, and helping to create safer, more civil shared experiences for everyone.
Robloxs database team develops the next-generation, multi-tenant database platform that elastically scales and underpins every online data workload at Roblox. As a principal 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 features indexing, storage formats, WAL and replication protocols, sharding, and query-planner enhancementsthat 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. You have: 8+ years
of experience in software engineering or a relevant field Deep experience with building and operating
large-scale distributed databases
or storage engines (e.g., PostgreSQL, MySQL/InnoDB, RocksDB, Spanner, Aurora, AlloyDB). Deep expertise in
database internals B-trees, MVCC, WAL, query optimization, buffer managementand strong skills in
C/C++, GO or Rust . Hands-on experience with
consensus algorithms
(Raft, Paxos) and multi-region replication models that deliver strong consistency and high availability. Proven success shipping
high-QPS, low-latency services
on container orchestration stacks (Kubernetes or Nomad) with comprehensive observability. Ability to turn ambiguous product requirements into a clear technical roadmap and influence cross-functional stakeholders. Passion for
automation, rigorous testing, and data-driven decision-making
that raises the reliability and efficiency bar. Bonus:
upstream contributions to PostgreSQL, RocksDB or other OSS databases; familiarity with disaggregated storage, HTAP workloads, or custom query languages.
