Job description

Build the web experience behind a rapidly growing connected gaming platform

A 100-year-old British consumer brand has acquired a fast-growing technology startup, combining physical hardware with a global online gaming platform.

The product uses a three-camera system to automatically track gameplay, score matches and connect players with people anywhere in the world.

It already has 200,000+ users, growing rapidly, with ambitions to reach the low millions.

They're now looking for a Frontend Engineer to help build what comes next.

The role

You’ll join a small engineering team at an exciting point in the product’s growth.

The focus is on modernising the existing web experience, building new features and making the product more engaging.

You’ll have genuine autonomy. This isn’t a role where you’re simply handed tickets. They’re looking for someone who spots problems, identifies opportunities and takes ownership.

You’ll work closely with engineering, product, design and growth across areas including:

• Accessibility
• New product features
• Gamification
• Performance and scalability
• Improving the overall user experience

The tech

Frontend: TypeScript, React

The engineering team is around 6 to 10 people across frontend, backend and computer vision.

You won’t need Go, but there’s scope to get involved beyond the frontend if that’s something that interests you.

What they’re looking for

They’re open on level. You could be a strong mid-level engineer or a senior engineer ready to take real ownership.

You’ll need:

• Strong commercial experience with React and TypeScript
• Experience building consumer-facing web products
• Experience working at meaningful scale
• The ability to make good technical decisions without needing constant direction
• The ability to work from the Reading office once a week

Bonus points for experience with gamification, real-time products, accessibility, subscriptions, Go, startups or AI coding tools.

This isn’t a traditional frontend role where you pick up tickets in a large engineering team.

You’re joining a small team with real autonomy, working on a product that’s already used by 200,000+ people and aiming for millions.

It’s a pretty unique combination of:

If you like owning problems, moving quickly and building products people genuinely use, this is a great one to get stuck into.
