• Collaborate with UX/UI Designers - translate prototypes into polished components, validate interactions, and iterate on feedback.
• Partner with Backend teams - define API contracts, optimise data payloads.
• Guard quality in the pipeline - maintain CI/CD scripts, automated tests, and lint rules; block regressions before they reach main.
• Mentor the team - review code, share patterns, and level-up Junior Engineers.
• Champion security and compliance - implement OWASP best practices, uphold requirements, and conduct regular audits.
• Monitor and iterate - Collaborate with the Site Reliability function to track real-world performance.

REQUIREMENTS

Advantageous
