Note: The job is a remote job and is open to candidates in USA. Flexhire is a stealth-mode startup building an operating system centered on AI agents, wearable technology, and on-device processing. The iOS Software Engineer will own the iOS and macOS applications, develop the agent interaction and memory interfaces, integrate local processing capabilities, and rapidly iterate based on closed-beta user feedback.
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
Benefits
- Meaningful early-stage equity
- Full medical, dental, and vision coverage
- Fully remote with occasional in-person time in Silicon Valley or Paris for key milestones
