• Strong written and verbal communication skills, including the ability to collaborate effectively across engineering and non-engineering partners.

Preferred Qualifications: 

• Experience with Protocol Buffers and gRPC, and TypeScript/JavaScript based backend frameworks and services
• Experience with Vitess or other large-scale SQL platforms.
• Experience integrating with internal and external APIs
• Experience working across a polyglot stack that includes backend and TypeScript-based clients and tooling.
• Practical experience using AI-assisted development tools such as Cursor, Claude Code, Gemini, or similar to improve engineering productivity and code quality.
