• Use data to monitor and improve login success rates, recovery flows, and engagement with privacy controls

• Participate in code reviews, design discussions, and on-call rotations

• Break down ambiguous problems into well-scoped, multi-component solutions and weigh technical trade-offs

What You'll Bring to the Team- 5+ years of software engineering experience, with fullstack range spanning mobile (iOS or Android) and backend/server systems
