Responsibilities

Own end-to-end features across the iOS app, including:

Chat experiences (composer, streaming updates, attachments, latency-sensitive UI)

Memory and personalization flows (capture, edit, display, privacy-minded UX)

Conversation experiences (threading, search, navigation, state restoration)

Group experiences (shared contexts, multi-user UX patterns, real-time-ish interactions)

Build high-fidelity Swift/SwiftUI UI with clean architecture, strong state management, and thoughtful component design

Work tightly with design to implement nuanced interaction details—gestures, transitions, micro-animations, haptics, while still preserving performance

Be performance-obsessed: profile and optimize frame rate, startup time, memory usage, and network/UI concurrency; eliminate stutters and regressions

Contribute to offline-first reliability: design resilient local persistence, caching, and sync behaviors so core experiences work under poor connectivity

Support on-device ML experiences (as needed): integrate CoreML/MLX-driven features and help optimize inference pipelines for latency, battery, and thermal constraints

Ship with quality: write tests where valuable, set guardrails against regressions, and partner with QA/release stakeholders to ensure stable releases

Collaborate cross-functionally: work with product and backend partners to scope, de-risk, and deliver features; communicate tradeoffs and options clearly

Bring strong product instincts: identify UX friction, propose improvements, and make pragmatic decisions that improve user outcomes and not just code elegance

Qualification

Required

5+ years of professional iOS development experience, with meaningful ownership of shipped features

Strong proficiency in Swift and SwiftUI, including building complex, interactive UI

Excellent understanding of iOS fundamentals: concurrency, data flow/state, networking, persistence, and debugging

Demonstrated ability to deliver high-quality UI and animations and to collaborate effectively with designers and motion specialists

Solid performance instincts: comfortable with Instruments, profiling, and systematically eliminating UI jank and memory issues

Experience designing robust client behavior in real-world conditions (spotty networks, backgrounding, app restarts, state restoration)

Strong communication and collaboration skills; reliable feature ownership from spec → implementation → launch

Preferred

Experience with offline-first architectures (local-first data models, sync engines, conflict resolution patterns)

Experience with on-device ML via CoreML and/or MLX, including model integration and optimization

Familiarity with Metal or GPU/performance concepts for advanced rendering or compute-heavy workflows

Experience improving product metrics (activation, retention, engagement) through iterative UI/UX improvements
