About the role

  • 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.

Requirements

  • 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.
Benefits
  • Competitive salary and performance-based incentives.
  • Comprehensive health, dental, and vision benefits package.
  • 401k Match (US-based only)
  • $200/mos Health and Wellness Stipend
  • $400/year Continuing Education Credit
  • $500/year Function Health subscription (US-based only)
  • Free parking, for in-office employees
  • Unlimited Approved PTO
  • Parental Leave for Eligible Employees
  • Supplemental Life Insurance
