What you'll doAs a mobile software engineer, you'll be the fourth engineer at a tiny startup, working closely with the whole team to design and build the native mobile experiences that power our gifting platform. You'll own our iOS and/or Android apps from architecture to pixel-perfect UI, building polished, performant experiences backed by clean API integrations.

- Build high-quality, fluid mobile UIs with attention to polish, animation, responsiveness, loading, and error states.

- Integrate with backend APIs and collaborate on API design to support mobile use cases.
- Collaborate with product, design, and the rest of the team to translate fuzzy goals into concrete flows and shipped features.
- Drive mobile architectural decisions to support scaling to hundreds of thousands of users.

- Experience with mobile CI/CD, automated testing, and release management (TestFlight, Play Console).
- Solid understanding of API integration, data modeling, and how systems fail in practice.
- Ability to take ownership of projects from vague problem 12 design 12 implementation 12 launch and iteration.
