iOS Developer / iOS Engineer / Mobile Developer / Mobile Engineer

Not every iOS role is about polishing UI or shipping the next consumer app.

This one is for an iOS engineer who enjoys owning the technical direction, working close to the platform, and dealing with the realities of performance, reliability and long-lived apps and SDKs in production.

Despite the title, this is not a people-management role. It’s a hands-on position for a senior iOS engineer who wants responsibility, influence and interesting technical problems - without stepping away from code.

What you’ll be working on

You’ll take ownership of iOS apps and SDKs used in real-world, data-heavy environments, where stability, correctness and long-term maintainability really matter.

Day to day, you will:

• Own the architecture and technical direction of iOS apps and SDKs
• Design and build complex features using Swift, with some Objective-C and C++
• Tackle challenges around networking, performance, stability and edge cases
• Stay ahead of iOS and Apple platform changes, shaping how the team responds
• Support SDK integrations and help resolve tricky production issues
• Run design and code reviews, and help raise engineering standards
• Make pragmatic use of modern tooling, including AI-assisted development tools, to improve quality and reduce busywork

Who this role suits

This role is a good fit if you:

• Like being the technical point of reference for iOS
• Enjoy thinking about architecture and long-term platform health
• Want influence and ownership without line management
• Are comfortable going deep when things break in production

You’ll likely bring:

• Strong experience building and shipping iOS apps in Swift (with some Objective-C)
• Solid understanding of iOS networking (HTTP(S), TLS, sockets, proxies)
• Experience integrating or working alongside native C++ libraries
• Good knowledge of iOS SDK/API design, versioning and supporting external integrators
• Familiarity with Apple Developer policies and how OS changes impact apps
• Strong debugging skills (crashes, performance, battery) and sensible testing practices

How you’ll work

• Hybrid role, Manchester-based
• 2 days per week in the office, the rest flexible
• Flexible start and finish times
• Full home-working setup provided

Nine years ago, a small team working alongside researchers at University of Oxford set out to solve a problem most of the world didn’t yet realise it had. Billions of machines were beginning to talk to each other — in factories, power grids, transport systems, defence networks and smart cities. But they were doing so through architectures built for a different era: centralised, fragile, and increasingly exposed. So, they built something different. Today, this UK tech company holds patented cryptographic technology that enables fully decentralised, post Quantum secure interoperability between devices — operating at the edge, without relying on always-on central connectivity. It works in untrusted environments. It enables real-time communication and narrow AI across full-scale industrial systems. And it is quietly moving from academic breakthrough to global security relevance. Now they need a senior C++ engineer who can operate where this technology truly lives — deep in the network stack. The Role: Where Packets Become Trust This is not application-layer C++. This is not framework-driven development. This is low-level, network-centric engineering, working primarily across OSI Layers 2 and 3, where routing decisions, tunnelling strategies and packet behaviour determine whether distributed systems can operate securely at scale. You will design and build software that ultimately runs on millions of industrial edge devices — enabling: \* Secure cloud ↔ edge communication \* Device-to-device authentication \* Decentralised routing and interoperability \* Robust deployment mechanisms for edge environments You will shape technical architecture, contribute to governance models, and help standardise innovative security solutions that could define the future of industrial IoT. Why This Matters This is a nine-year-old UK technology business that has moved from academic roots to patented, commercially relevant security infrastructure. It is no longer a concept. It is not a slide deck. It is production-grade technology preparing for global scale. The successful candidate won’t just write code. They will help determine how critical infrastructure, industrial systems and smart cities authenticate and communicate for decades to come. You’ll receive a competitive base salary, significant equity, and the chance to work on technology that sits at the intersection of networking, cryptography and national-scale resilience. If you are a serious C++ engineer who understands packets, routing, tunnelling and kernel-level behaviour — and you want your next role to genuinely matter — this may be worth a conversation.
