iOS Software engineer — Agentic AI Platform

Summary

Flexhire is a stealth-mode startup focused on building the operating system for the next generation of computing. They are seeking an iOS Software Engineer to own and develop their iOS and MacOS applications, iterating based on user feedback to create a unique client experience.

Responsibilities

• You will own our iOS and MacOS applications, and be responsible for iterating rapidly based on early user feedback, and expand it into the full MVP experience — building the client layer that makes our Agentic OS feel genuinely different from anything users have experienced before
• You will work directly with the CEO and a small, high-trust engineering team across Silicon Valley, Paris
• This is a hands-on engineering role with significant influence over how the platform feels to use — not just how it works
• The core iOS client for our Agentic OS — iterating on an existing Swift/SwiftUI codebase and expanding its capabilities toward full MVP release
• The agent interaction layer — the surface through which users experience always-on contextual AI for the first time, with no app icons, no menus, and no friction
• The memory and context UI — making the platform's persistent, encrypted memory layer feel intuitive and trustworthy to users
• A companion mode that previews the wearable device experience — giving early users a window into what platform will feel like as a wearable before the hardware ships
• On-device processing integrations — working closely with the backend team to minimize cloud dependency and maximize what runs locally on device
• A feedback and iteration loop with closed beta users — this is a friends and family release and you will have direct access to real user reactions

Skills

• 4+ years of iOS engineering experience with strong Swift and SwiftUI skills
• Deep understanding of iOS platform patterns — lifecycle, state management, background processing, permissions, notifications
• Experience building consumer-facing products where UX quality and interaction polish matter as much as technical correctness
• Comfort inheriting and improving an existing codebase rather than building exclusively greenfield
• Active user of AI-assisted development tools with a genuine point of view on how to use them well
• Strong written English and proven ability to work effectively in a remote and distributed team
• Must be authorized to work in the US
• Familiarity with on-device ML frameworks — Core ML, Create ML, or similar — is a strong plus given our emphasis on local processing
• Strong plus: experience with always-on or background audio processing, privacy-preserving on-device data architectures, wearable or AR companion app experience
