Full Stack Web Developer

At Energym, we’re building the next generation of indoor cycling — high-performance smart bikes that don’t just track workouts, they generate clean, usable energy. Our RE:GEN bikes capture rider power, store it in portable batteries, and power experiences for homes, studios and partners.

We’re now looking for a Full Stack Web Developer to help us ship fast, secure, high-quality web applications that sit at the heart of the product experience — and connect seamlessly with deployed hardware in the real world. Day to day you'll be:

• Building and maintaining modern web apps across the full stack (front end + back end)
• Working closely with product/engineering to integrate web platforms with deployed hardware devices
• Designing and integrating third-party RESTful APIs
• Optimising for performance, scalability and security (we care about the details)
• Writing clean, maintainable, well-documented code
• Taking part in code reviews and helping raise the bar on best practices.

• At least one of:
  • Professional experience in web development
  • A Git portfolio showing real projects/contributions
  • A degree in Computer Science / Software Engineering (or similar)
• Strong fundamentals: HTML, CSS, JavaScript and/or TypeScript
• Confidence in one modern front-end framework (React / Vue / Angular / Svelte)
• Server-side experience (Node.js, Flask, ASP.NET, or similar)
• Team collaboration experience using Git

Bonus points if you have

• Svelte / SvelteKit + Tailwind CSS
• Cloudflare Workers or serverless experience
• PostgreSQL (or similar relational DBs)
• Auth knowledge (OAuth, tokens, sessions)
• Docker / containerisation
• Familiarity with modern build tooling + deployment pipelines
