- Engineering Maturity: You understand TDD, CI/CD, and how to build resilient distributed systems.
- Collaboration: You enjoy mentoring, peer-reviewing, and raising the bar for an entire engineering organisation.
- Tech-Agnostic: You’re comfortable working across the stack or even moving into new domains (Fullstack, Data, or Platform).
