Nice to have - Prior exposure to AI-assisted coding tools in a professional or personal setting.

Benefits and work setup - Pacific time zone working hours expected. - Advanced spoken and written English required for daily collaboration. - KPIs emphasize on-time sprint delivery, code review quality, zero critical production bugs, and test coverage on new code.
