Senior Software Enginner

The candidate will have responsibilities across the following functions:

Build:

• Build features across Neo's cross-platform apps (React Native / Flutter), the interfaces where people delegate work to Friday and pick up Tasket, Studio, and Scribe on the go.
• Take a spec to a shipped feature by directing agents through implementation, then reviewing the result against device behaviour, not just the simulator.

Architecture and systems judgment:

• Own components and screens end-to-end: state management, navigation, and how they hold up under real network and device conditions.
• Contribute to design discussions on offline behaviour, sync, and app performance.

Agent leverage:

• Use agents to move from spec to working UI quickly, then validate the output by hand against the craft and correctness bar.
• Structure well-defined tasks a screen, a component, a bug so agents can execute them reliably.

Quality and ownership:

• Own performance and correctness on real devices: startup time, jank, memory, and behaviour across OS versions and screen sizes.
• Triage and fix crashes and platform-specific issues; keep release quality high across app store submissions.

Requirements:

• AI-native engineering practice: Comfortable directing coding agents against a clear spec and validating their output against device-level reality, not just what compiles.
• Cross-platform mobile fundamentals: Solid command of React Native/TypeScript (preferred) or Flutter/Dart, including state management, navigation, and the native bridge/platform-channel layer when you need to drop below the framework.
• Native platform awareness: Working knowledge of Android and iOS build, release, and permissioning models enough to debug a platform-specific issue without waiting on a native specialist.
• Performance and reliability: Reasons about startup time, rendering performance, offline/sync behaviour, and memory use on real, low-end devices, not just flagship hardware.
• API integration: Comfortable consuming REST/GraphQL APIs, handling auth, and building resilient network and caching layers for a mobile client.
• 4+ years building and shipping production mobile apps.
• 1+ years in React Native (preferred) / Flutter, or equivalent cross-platform frameworks.
• Have taken at least one app through real app-store release and iteration cycles.
• Bachelor's degree in Computer Science or equivalent practical depth.
