Looking for your next big opportunity to own a product from the ground up?

Join a pioneering sports tech start-up building an AI-powered mobile coaching app for skiers — helping users improve technique through video analysis and real-time feedback.

This is not a typical dev job — you’ll be working on something genuinely innovative, using joint-tracking tech, video streaming, and AI-powered coaching, with a roadmap toward becoming the CTO.

About the App

The app (with an early prototype already built) allows users to upload skiing videos, analyse movement using joint-tracking technology, and receive constructive feedback through an AI-powered chat assistant. You’ll help transform this into a fully functional, scalable product ahead of the next ski season.

About the Role

You’ll lead full-stack development (React Native + Node.js), collaborating closely with the founders and UX designer in an iterative, design-driven process. This is a greenfield opportunity where you’ll shape the technical architecture, development roadmap, and future team.

Key responsibilities:

• Develop and own the mobile app front to back (React Native + Node.js)
• Build scalable APIs, cloud infrastructure, and CMS integrations
• Work from Figma prototypes through to production code
• Integrate AI tools and video analysis engines into a seamless user experience
• Optimise joint-tracking tech for accuracy and real-world performance
• Set the foundation for future team growth and CTO-level leadership

Some UK travel may be needed for testing on indoor/dry ski slopes.

What We’re Looking For

We’re seeking a senior developer (or strong full-stack engineer) ready to take ownership and step into a leadership role.

Essential skills and experience:

• Proven experience building production-grade mobile apps (ideally with React Native)
• Strong back-end development with Node.js and scalable cloud infrastructure (AWS, GCP or Azure)
• Comfortable with relational (PostgreSQL) and NoSQL (Firestore) databases
• Experience with video capture, playback, and media handling on mobile
• Understanding of AI integration, or willingness to learn rapidly
• Comfortable working independently in a fast-moving start-up environment

Nice to have:

• Experience with LLM-based chat agents or feedback generation tools
• Background in joint-tracking, movement analysis, or sports tech
• Familiarity with CMS platforms (e.g. Contentful, Strapi) and dynamic content workflows
• An interest in skiing, coaching, or sports performance apps

Why Join?

• Full ownership of an exciting greenfield product
• Opportunity to progress into a CTO role
• Flexible working hours and remote-first culture
• Input into technical decisions, roadmap, and team structure
• Bespoke benefits and possible equity or share options
