• Own feature delivery end-to-end: Take features from technical design through to deployment. Contribute to sprint planning, backlog refinement and ensure work is well-tested and maintainable.

• Contribute to engineering standards: Participate in code reviews and promote clean architecture and maintainable patterns. Improve test coverage, CI/CD pipelines, and deployment practices. Help reduce technical debt through pragmatic refactoring.

• Support AI-enabled features: Contribute to the implementation and integration of AI-driven capabilities within the platform. Rapidly prototype and validate ideas, using insights to shape both technical execution and product direction. Champion the strategic growth of AI in the product, ensuring alignment with company goals and long-term vision.

• Team mentorship & capability building: Act as a mentor and technical leader within the dev team. Foster a culture of continuous learning and shared ownership, helping the team grow both technically and professionally.
