Build resilient Swift and Objective-C++ code that integrates with shared native components, connected devices, and backend services, while establishing a strong testing strategy.

Description
About FindiFox
FindiFox is building privacy-first positioning technology for child safety.
Our first product, Spark One, is a small wearable and app that helps parents find their child fast in the crowded, indoor and multi-floor places where GPS gives up.
We're a Dorset startup, and this month we started an 18-month R&D project backed by Innovate UK.
The role
You'll own the iOS app that parents rely on when it matters most.
That means everything from a calm, clear interface to the deep background work: Bluetooth, location, and the link between the phone, our wearable and our servers.
You'll work in Swift and Objective-C++, bridging the app to our shared C++ core, which also runs on Android, our OpenBSD servers and our Zephyr-based firmware.
What you'll do
Design and build the iOS app, from the interface through to background Apple servicesWrite resilient Swift and Objective-C++ that talks reliably to our firmware and serversSet the testing strategy for a safety product, where reliability isn't optionalOwn CI/CD and App Store releasesTake ownership of milestones, architecture decisions and documentation
What you'll need
5+ years designing, building and shipping production iOS appsStrong Swift, and working Objective-C++ (or solid C++ alongside Objective-C)A good grasp of networking, data security and encryptionThe rigour to turn strict safety requirements into robust codeConfidence to own a module end to end, and experience working with external teams and contractorsGit and JiraBased in the UK with the right to work here (we can't sponsor visas), and able to get to Poole or Bournemouth occasionally
Nice to have (nobody has all of these, and we don't expect you to)
