Senior iOS Engineer, webAI

• This is a highly hands-on role for someone who cares about craft, speed, and product outcomes and who can take a feature from idea to launch with minimal oversight
• 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

Desirable

• We’re hiring a Senior iOS Engineer to build and ship core product experiences on iOS, especially chat, memory, conversations, and group experiences
• You’ll work closely with the design team to deliver polished, high-performing UI that feels effortless
• 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
