• Deep familiarity with iOS security APIs (Keychain, Data Protection, Secure Enclave, App Attest)
• Experience building offline-first apps with robust sync and conflict resolution
• Comfortable with CI/CD for mobile (Fastlane / Xcode Cloud), TestFlight distribution, and App Store review processes
• Strong product design sense - experience in app design, with a keen eye for craft, motion, and the details that make an app feel native
NICE TO HAVE
• Experience with RAG pipelines, vector databases, or AI-agent architectures
• Published open-source Swift packages or technical writing on iOS architecture
• WatchOS or visionOS prototyping experience
WHAT YOU’LL BUILD
• Native SwiftUI interface for Fluso’s conversational AI, task management, and knowledge-graph views
• On-device inference pipeline for privacy-sensitive operations (local embeddings, summarization, PII
redaction)
• Deep integrations with system frameworks - WidgetKit, Siri Shortcuts, Spotlight indexing, push
notifications, App Intents
• Real-time sync engine with the Fluso backend (WebSocket + incremental REST), handling offline-first
conflict resolution
• Secure credential storage and end-to-end encrypted channel for connected accounts (Gmail, Calendar,
Slack, Drive)
• Multi-window iPad experience with stage manager support and keyboard-first workflows
