High Ownership, Real Product, Real Impact
The opportunity
If you’re a developer with a couple of years under your belt and you’re starting to look for more ownership, more responsibility, and faster growth, this is a rare opportunity to join at exactly the right moment. Staxy are at a stage where the product is live, customers are engaged, and the technical challenges are only getting more interesting. What they need now is someone who’s excited to step up, learn fast, and grow alongside the company.
Who are Staxy?
Staxy is an early-stage technology startup building products that sit at the intersection of sport, location data, and real-world behaviour. They work with organisations to better understand how people move, engage, and interact with physical spaces, using mobile technology, location data, and analytics to generate meaningful insight. They’re already live with Aston Villa as a cornerstone client, have secured VC funding, and are seeing strong pull from customers who are actively asking them to expand the product. Backed by an experienced board with deep roots in sport and commercial leadership, Staxy are well past the “idea stage” and firmly into building and scaling.
The role
This is a full stack developer role with genuine ownership. You’ll work closely with the CTO, and other founders, and will be involved across the full product lifecycle, from shaping features through to shipping them.
Day to day, you’ll be:
- Building and shipping features across a mobile application and backend platform
- Working end-to-end, not just on isolated tickets
- Collaborating directly with the CTO on product priorities
- Taking ownership of smaller features early on, and growing into larger features and technical decisions over time
You won’t be micromanaged, and you won’t be siloed. The expectation isn’t that you know everything, it’s that you’re curious, proactive, and keen to learn.
The technology
You’ll be working with a modern, pragmatic stack:
- Mobile / Frontend: React Native, TypeScript
- Backend: Node.js (Fastify or similar)
- Data: MongoDB
- APIs: RESTful services and mobile-to-server communication
- Other: Mapping / location-based services
There’s also scope to get involved in machine learning over time. Staxy already use ML to process GPS data and understand travel behaviour, and this will become a bigger focus as the platform evolves. You don’t need ML experience right now, interest and curiosity are enough.
Key responsibilities
- Build and ship features across the mobile app and backend
- Develop and consume REST APIs
- Write clean, maintainable TypeScript
- Work closely with the CTO on technical decisions and implementation
- Take increasing ownership of functionality as you grow
- Contribute ideas and improvements as the platform evolves
What we’re looking for
Must have:
- Around 2–3 years’ experience as a developer
- Good working knowledge of JavaScript / TypeScript
- Experience building and shipping real features (ideally mobile)
- Some exposure to Node.js and backend development
- A genuine curiosity and desire to learn
Nice to have:
- React Native / Expo experience
- MongoDB
- Fastify or similar Node frameworks
- Mapping or location-based services
- Payments (e.g. Stripe)
- Any exposure or interest in machine learning
