Senior Software Engineer

Want to build systems that talk to millions of customers — and actually make those conversations smarter?

At Checkatrade, we’re on a mission to make home improvement simple, trusted, and fair. Behind the scenes, that means powerful CRM and marketing platforms that help us communicate with homeowners and trades at exactly the right moment.

As a Senior Software Engineer in our CRM Engineering team, you’ll be right at the centre of that mission. You’ll design and build the services that power our customer communications, marketing automation, and data-driven engagement — working closely with Marketing, Product, and Data to turn ideas into impact.

This role is perfect for a well-rounded, full-stack engineer who enjoys variety: a mix of roadmap-driven development, hands-on problem solving, and shaping how we use technology for smarter, more personalised experiences.

• Designing, building, and scaling services that underpin our CRM and marketing capabilities

• Turning loosely defined business problems into clear technical solutions — and owning them end to end

• Balancing quick wins with long-term improvements to keep our systems robust and future-ready

• Working closely with Marketing, Data, and Product to deliver meaningful outcomes, not just tickets

• Mentoring other engineers through pair programming, code reviews, and thoughtful technical discussion

• Helping shape the future of our CRM and data platform, including how we use automation and AI

You’ll work in a hybrid model, spending two days a week in our Moorgate office, collaborating with a small, focused team that values autonomy and impact.
