We expect developers to:
- Ship work in testable increments
- Keep changes reviewable and well-scoped
- Raise blockers early
- Respect UI and implementation guidance
- Align work with acceptance criteria, smoke testing, and UAT expectations
- Improve quality while continuing delivery
Our platform documentation also includes implementation standards around Figma-to-Unity workflows, UI adaptivity, code style, architecture, and development guidance, which this role will need to work within.
What you’ll get from us
