• Comprehensive automated testing — unit, integration, end-to-end. 90%+coverage is the baseline.
• Autonomous operator — proven ability to work with minimal product management support.
• Strong English communication — written and verbal (C1 minimum). Engineers communicate directly with senior client stakeholders.
• US timezone overlap — comfortable working in Pacific / Central time zones.
