About the Role

We're seeking a talented individual who can tackle challenges in networking, database architecture, query optimization, caching, and microservices design. You'll work closely with our DevOps team to realize these goals using our modern cloud-native infrastructure and best-in-class tooling.

Your Responsibilities
  1. Optimize Database Performance: Improve the performance and scalability of our databases through identifying and improving query hotspots, making schema improvements, and tuning the underlying systems.
  2. API Performance Optimization: Enhance API performance by reducing end-to-end request latency and increasing throughput through techniques like tuning worker pools, connection pools, caching, and leveraging tools like ProxySQL.
  3. Code-Level Insights: Analyze, read, and modify code across various services to identify and fix performance bottlenecks.
  4. Performance Monitoring: Design and maintain dashboards that provide actionable insights into performance across our systems.
  5. Collaborative Problem Solving: Partner with engineering teams to investigate and resolve platform-wide performance issues.
  6. Mentorship: Share your expertise with the engineering team, teaching best practices for database performance, profiling, and scalable system design.
  7. Operational Accountability: Take responsibility for ensuring platform performance meets SLAs, including participating in an on-call rotation to address and mitigate performance-related incidents.
Your Skills and Qualifications
  • 5+ years of engineering experience with a strong focus on performance and system optimization.
  • Deep understanding of database internals and optimization techniques, particularly for MySQL and PostgreSQL.
  • Strong knowledge of Linux systems and networking (e.g., TCP/IP, load balancing, DNS).
  • Practical experience with Kubernetes, including understanding its impact on performance and scalability.
  • Hands-on experience with tools like eBPF, flame graphs, and other profiling techniques inspired by Brendan Gregg's methodologies.
  • Familiarity with cloud services (AWS, GCP) and their database offerings (e.g., RDS, managed PostgreSQL/ClickHouse).
Bonus Points
  • Experience optimizing global network performance using cloud tooling to leverage edge caching, early TLS termination, HTTP protocol optimization (e.g., HTTP/2/3 or QUIC), etc.
  • Familiarity with tools like Terraform for automating and managing infrastructure deployments.
  • Contributions to open-source projects, especially in the database, performance, or observability domains.
