Job description

Senior Software Engineer

We’re building fast. And we’re looking for engineers who want in. If you have 0-1 build experience, lets talk.

At Checkatrade, we’re transforming how tradespeople work – and we’re doing it properly. No feature factories. No rebrands of old tech. We’re talking greenfield, high impact builds, designed from scratch to solve problems for real users.

We’re now hiring Senior Engineers to help us push this new product forward. You’ll join a small, sharp, product focused team with full ownership, working in fast feedback loops and constantly experimenting to get to the best solution – fast. We need real 0-1 build experience, not just adding to existing codebases.

This isn’t just an engineering role. It’s product, it’s architecture, it’s delivery. And it’s backed by a company that’s investing hard in tools, talent, and AI.

Location: London, Kings Cross (Hybrid) or Remote.

What you’ll be doing

· Designing and building greenfield services and systems from the ground up

· 0-1 build experience, not just adding to existing codebases.

· Working with autonomy to make smart engineering decisions

· Experimenting rapidly – prototype, test, and iterate while maintaining high standards

· Building high-performance, well tested, and maintainable code

· Playing a key role in architecture and systems designs discussions

· Helping shape the product and engineering culture with your ideas and experience

· Using AI tools in your day to day workflow to speed up and improve delivery

Tech we use
• TypeScript, React, Node.js
• GraphQL, PostgreSQL
• Terraform, GCP
• AI tooling integrated into our dev stack

What we're looking for

• Experience building and shipping high-quality products in fast-paced environments
• A strong grasp of scalable architecture, testing and clean code principles
• Solid experience across our core stack (or close equivalents)
• Confidence working in autonomous, agile teams
• Curiosity, creativity, and the drive to keep learning
• Bonus points for experience using AI in real-world workflows

Why Checkatrade?

We’re not your average tech company. We’re combining the pace and mindset of a start up with the backing and reach of a trusted brand. You’ll be part of a product-led team that values speed, innovation, and clarity – not endless process or layers of approval.

We’re building fast. We’re scaling smart. And we’re doing it together.

Apply now – we’d love to hear from you.
