Job description

This job is brought to you by Jobs/Redefined, the UK's leading over-50s age inclusive jobs board.

Join us as a Senior Software Engineer (LABs)

Want to do work that really matters?

At Checkatrade, we're building the UK's go-to home improvement marketplace. Every day, we help millions of homeowners find the right tradesperson for the job, fast, fair, and without the faff.

As our next Senior Software Engineer (LABs), you'll shape and deliver the technology, tools, and innovations that connect homeowners with the right trades, making every job simpler, faster, and more reliable. You'll be part of our experimental product team, where we launch early-stage products with startup speed, but with the backing of a household name. You'll build MVPs, test bold ideas, and own products end to end. No big backlogs. No long handoffs. Just autonomy, creativity, and code that actually ships.

Forget long lists, here's what you'll actually spend your time on:

• Delivering greenfield builds that go from zero to MVP in days, not months.
• Spotting ways to ship smarter, choosing the right tools, frameworks and architecture for speed and scale.
• Collaborating with a product partner to define, test and launch new marketplace experiments.
• Making sure every build is fast, functional, and focused on learning something real.

It's not about ticking every box. It's about turning up curious, ready to crack on. You'll do well here if you bring:

• Experience building early-stage or greenfield products in fast-paced environments.
• A collaborative, roll-up-your-sleeves attitude.
• Strong communication skills and a love of solving real-world problems.
• Confidence with modern stacks (Node.js, TypeScript, React) or the hunger to learn fast.

We believe great work deserves great rewards. Here's just a taste:

• Competitive salary + annual bonus
• Health, well-being and learning support
• Gym membership, Smart Tech Scheme and Cycle Scheme
• Birthday/Special day leave
• Buy & sell holiday scheme
• 1 week's paid charity leave and much more!

How we'll get to know each other:

• Screening call with one of our Talent Acquisition Partners
• 1st stage interview with our Engineering Manager
• 2nd Stage interview with our Principal Engineer and Full Stack Engineer
• 3rd interview will include a technical task with our VP of Labs and Director of Product Engineering

If you require any reasonable adjustments during our interview process, please discuss them with your Talent Acquisition Partner.

Take it from one of our current engineers: "No two days look the same in Labs - one day I'm building an MVP from scratch using Next.js and Firebase, the next I'm pairing with our product lead to design an experiment or jumping on calls with real users to test assumptions. I get to own the tech end-to-end, choose the right tools for the job, and move at startup speed - but with the support and reach of a trusted brand behind me. It's the most autonomy I've had in any role - and the most fun I've had shipping." - Senior Engineer, Labs @ Checkatrade
