Job description
- The Mobile Engineer owns the True Markets mobile app end to end — native Swift on iOS and native Kotlin on Android, built in a single repository and shipped on an eight-to-ten-day release cadence. Scope covers the trading surfaces — spot and perpetuals order entry, quotes, positions, and P&L — along with portfolio and charting, onboarding and KYC, deposits and withdrawals, and passkey authentication. This is a small team: the role scopes its own work, cuts its own releases, and works directly with backend and design.
Responsibilities
- Build and ship features across both native codebases — Swift and SwiftUI on iOS, Kotlin and Compose on Android — holding the two at feature parity.
- Own the release process: version cuts, TestFlight and Play internal builds, store submission, review responses, and post-release monitoring.
- Own the trading surfaces — order submission, quoting, position and P&L display, order history.
- Maintain authentication and onboarding, including passkey, 3p logon integrations, and wallet session management and KYC.
- Instrument the app: analytics events and funnels, feature flags, crash and error monitoring.
- Maintain mobile CI/CD — GitHub Actions, self-hosted macOS runners, signing, and secrets.
- Triage incoming bugs and run the weekly UI review.
- Define API contracts with backend engineers and resolve interface behavior with design.
Requirements
- 5+ years building and shipping production mobile applications.
- Deep expertise in Swift and SwiftUI, with working fluency in Kotlin and Compose — or the reverse. Both codebases are in scope.
- Owned a release end to end: signing, provisioning, submission, and store review.
- Experience with real-time data on mobile — streaming prices, WebSocket connections, and state that survives reconnects.
- AI-native: Claude Code or comparable agentic tooling as a daily force multiplier, with strong instincts for when to trust it, when to verify, and how to push it harder.
- Strong written communication and high autonomy in a small team.
- Crypto, fintech, or trading background — order entry, margin, perpetuals, or settlement.
- Familiarity with non-custodial key management, passkeys, or MPC wallet infrastructure.
- Experience with identity and KYC onboarding flows.
- Hands-on with product analytics and feature flagging, and crash reporting.
- Mobile CI/CD depth: GitHub Actions, self-hosted runners, merge automation.
- Comfort dropping into backend services to unblock an API change.
- Shipped an app of your own, or contributions to mobile open source.
