Senior Mobile Software Engineer

At Cyclops Technologies, we're making load-sensing technology accessible and impactful across marine, fitness, and industrial applications. Our solutions help Olympic sailors optimize performance, enable gyms to transform member experiences, and help industrial operators work more safely and efficiently. Now, we're seeking a Senior Mobile Software Engineer to lead the development of applications that bring our hardware capabilities to life.

The Opportunity

As our first mobile-focused hire, you'll spearhead the development of applications that not only support our hardware sales but also create new revenue opportunities through white-label offerings and future consumer applications. You'll work at the intersection of hardware and software, creating intuitive experiences that process real-time data from our innovative devices.

What Success Looks Like

In your first year, you'll:
• Write and ship production code across our mobile apps and SDK.
• Implement robust Bluetooth communication between our apps and hardware.
• Build automated test suites and CI/CD pipelines that ensure reliable releases.
• Establish clean architectural patterns through practical refactoring.
• Support B2B partners with SDK integration, including code examples and troubleshooting, and with white-label and bespoke app development.
• Help grow our mobile team, including mentoring a junior engineer in 2025

By succeeding in this role you’ll be helping Olympic sailors to optimise performance, gym goers to improve their health, increase safety and confidence for people working at height and many more. Along the way that will drive revenue for Cyclops both in software sales and in support of sensor sales.

Technical Requirements

Must Have:
• 5-8 years software engineering experience (3+ years industrial).
• Strong mobile development background in either Swift/iOS or Kotlin/Android.
• Expertise in mobile architecture patterns, testing, and CI/CD.
• A-level Maths and Physics.
• Solid understanding of data structures and algorithms.

Nice to Have:
• Cross-platform mobile development experience.
• BLE communication background.
• SDK development experience.
• Experience with Firebase or similar backend services.
• Track record of building consumer-grade UX.

Your Working Style

You are:
• Passionate about writing clean, maintainable code.
• Skilled at breaking down complex features into implementable chunks.
• Pragmatic about balancing technical debt with delivery.
• A clear communicator who raises blocking issues early.
• Give priorities can work independently and maintain momentum without close supervision
• Strong at collaborative work, especially when working with folks with other technical specialisms (the hardware team in our case).
• Excited about learning and applying new technologies thoughtfully.

Why Join Us
• Shape the technical direction of a growing mobile team, including guiding choices on tooling, architecture and process. We’re excited about the possibilities of building our process around AI tooling.
• Flexibility to take a development path to either principal IC or a tech lead role.
• Work with cutting-edge hardware and real-time data.
• Join a funded startup on track for profitability in 2025.
• Hybrid working model (2-3 days in office) that combines focused development time with collaborative hardware integration.
• This role will be based in our Cambridge office, with occasional travel to our HQ in Portsmouth, UK.
• Competitive Senior Engineer compensation plus stock options.

We're building a software team that will grow over the coming years. This is an opportunity to shape both our technology and our team from the ground up, creating the foundation for our next phase of growth.
