Job summary

Roblox Corporation is seeking a Senior Software Engineer for the Roblox Database team. You will design and implement engine features, optimise database internals, and lead efforts to scale and secure large, multi-region data workloads.

You will mentor engineers, contribute to the open-source community, and help shape the control plane for elastic, zero-downtime operations across global regions. This role emphasizes performance, reliability, and collaboration.

Qualifications

• 6+ years of software engineering experience.
• Extensive experience with large-scale distributed databases or storage engines.
• Deep knowledge of database internals (B-trees, MVCC, WAL) and languages C/C++, Go or Rust.

Responsibilities

• Design and implement new engine features - indexing, storage formats, WAL and replication protocols, sharding, and query-planner enhancements.
• Evolve the control plane to deliver elastic scaling, autonomous healing, and zero-downtime schema or tenant moves across regions.
• Profile and optimize critical code paths with tracing and performance tooling to reduce tail latency.
• Establish engineering best practices by leading design reviews, performance benchmarks, and incident retrospectives.
• Automate testing, CI/CD, rollout safety, observability, and autoscaling for hands-off operation at scale.
• Mentor engineers and share knowledge across Storage, Platform, and product teams.
