• Write automated tests (unit, integration, end-to-end) using Jest, Mocha, Supertest, or similar frameworks
• Conduct code reviews, mentor mid-level engineers, and contribute to engineering documentation and best practices
• Collaborate with product, design, and engineering leadership across time zones to scope features, define API contracts, and deliver end-to-end
