Job description

Overview

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 (CRM)

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. Forget long lists. Here\'s what you\'ll actually spend your time on:

• 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.

Our tech stack (the good stuff):

Core technologies

• Node.js & TypeScript (primary backend)
• React & Next.js (frontend)
• PostgreSQL & Firestore
• Google Cloud Platform
• BigQuery
• Pub/Sub (event-driven architecture)

CRM & marketing

• Braze (customer engagement)
• Salesforce (CRM integration)
• Analytics Gateway (event tracking & data flow)

It\'s not about ticking every box. You\'ll do well here if you bring:

• Strong experience as a full-stack engineer, ideally with Node.js and TypeScript
• A solid understanding of SQL and how data flows between systems
• Experience with, or curiosity about, CRM/CDP platforms (Braze, Segment, Salesforce, or similar)
• A track record of owning delivery - shaping requirements, planning work, and seeing it through
• Comfort working in a fast-moving team with both planned roadmap work and reactive support
• Genuine enthusiasm for learning - especially around AI, automation, and smarter data-driven systems

Why join Checkatrade?

• A small, empowered team where your work has real visibility and impact
• A modern tech stack and strong engineering culture
• The chance to shape how we engage millions of customers using data and technology
• Hybrid working with flexibility built in
• Investment in your growth, including access to cutting-edge AI tools and training

How we\'ll get to know each other:

• Initial chat with one of our Talent Acquisition Partners
• Interview with the CRM Engineering team
• Technical stage case study or Task

Need adjustments? Let your Talent Partner know - we\'re happy to help.
