Senior Software Engineer (Mobile Platform)

Join our team as a Senior Software Engineer II - Mobile Platform. In this role, you will lead the technical direction of our React Native app, ensuring its security, compliance, and overall performance. You will work with significant autonomy, mentor other engineers, and be the go-to person for keeping the app secure and up-to-date. Additionally, you will modernize and maintain the tech stack, improve our delivery pipeline, and support the app in production. This position offers a competitive benefits package, including an open vacation policy, full benefits, and generous stock options.

• Lead the technical direction of the React Native app, focusing on security posture, dependencies, CI/CD, and documentation.
• Mentor other engineers and serve as a technical leader for the codebase across iOS and Android, contributing to feature development and architecture.
• Improve CI/CD automation, quality and security gates, and signed release flows, managing code signing, credentials, and versioning.
• 7+ years of professional software engineering experience (or 4+ with a Master's, or equivalent), with a strong track record shipping production mobile applications
• Deep React Native / Expo experience, with comfort going native — Xcode/CocoaPods, iOS build and signing, Android/Gradle, and writing or debugging native modules. We have custom native bridges; you should be comfortable navigating them. Depth on one platform with genuine curiosity about the other is welcome
• Current with the mobile ecosystem. You track platform changes, security developments, and tooling — and bring that knowledge to the codebase proactively
• A strong security mindset, with hands-on experience in mobile authentication (OAuth/OIDC, Okta, MSAL/Microsoft identity) and ideally mobile device/app management (Intune MDM/MAM) and secure PII handling in regulated environments
• Proven mobile CI/CD and release engineering experience — automating builds and store delivery to TestFlight and Google Play (EAS Build/Submit, Fastlane, GitHub Actions, or similar), managing certificates and provisioning profiles, and running OTA update channels
• A bias toward durability and clarity. You leave the codebase, pipeline, and docs better than you found them, and write things down so the whole team can build on your work
• Strong judgment and autonomy. You're comfortable with a wide scope, recognize connections across the codebase and toolchain, and drive improvements rather than waiting for direction
• A collaborative, low-ego approach. You communicate openly, amplify the people around you, and take shared accountability for team outcomes
• At this time, we are only able to consider candidates who are currently authorized to work in the U.S. and will not require sponsorship now or in the future
