  • Proficiency in the C++ Standard Library (STL) and Boost C++ Libraries
  • Expertise in: GCP Pub/Sub, and REST/JSON APIs (gRPC is nice to have)
  • Understanding of: OAuth2, JWT, and cloud security best practices
  • Solid knowledge of algorithmic thinking and distributed systems architecture, including consistency, durability, and failure/resiliency considerations
  • Fluency in Git-based workflows and large-scale CI/CD toolchains (GitHub Actions); scripting (Python/Bash) to support automation, tooling, and operations
  • Strong understanding of NoSQL data modeling and document design, including denormalization strategies and evolution/versioning of schemas
  • Experience building migration/ETL processes, data backfills, and reconciliation/validation tooling to ensure functional equivalence during cutover
  • Strong understanding of object-oriented programming principles, common design patterns, and clean code best practices
  • Good Unix/Linux knowledge and experience developing, debugging, profiling, and operating services in Linux environments (including large-scale/legacy codebases)
  • Hands-on experience with performance engineering, including profiling, benchmarking, load testing, stress testing, scalability testing, and root-cause analysis of performance bottlenecks in distributed systems
  • Experience using performance analysis and observability tools
  • Experience working with AI Tools (Copilot/Agentic)
  • Experience migrating or modernizing persistence layers, including rewriting applications from legacy object databases (e.g., Versant) to distributed NoSQL platforms (e.g., Couchbase)
