• Refactor legacy or externally developed systems into clean, maintainable Node.js services.

• Write automated tests and ensure appropriate engineering quality gates.

• Troubleshoot production issues and contribute to observability and operational improvements.

• Collaborate closely with product, engineering, and business stakeholders.

• Make pragmatic architectural decisions in a fast-moving environment.

Qualifications:

• Strong commercial experience with Node.js / JavaScript / TypeScript

• Strong API and backend development experience

• Experience building and integrating REST APIs and other service interfaces

• Strong understanding of software architecture and engineering principles

• Experience working with AWS
