Mobile Engineer (iOS / Android)

This is hands-on, product-focused engineering: designing screens, tuning performance, handling offline states, and shipping releases on a tight cadence. The team ships frequently and owns what it builds end-to-end. Mobile engineers here work directly with backend engineers and designers, and are expected to understand the full stack well enough to push back on API design when it matters.
