Job description

Help Build the AI Defence Systems of Tomorrow
At Compare the Market, we’re building a cyber immune system, a self-adaptive layer of defence that uses AI to detect, assess, and respond to threats faster than ever before. To make this real, we’ve launched Project Wingspan: a bold reinvention of how we respond to operational and cyber risk using safe, collaborative AI agents.
We’re looking for a Software Engineer to help shape this future. You’ll work at the intersection of engineering, security, and AI to build systems that support real-time, human–AI collaboration at scale. This is a greenfield mission with impact, you’ll be designing the platforms, tools, and patterns that will underpin intelligent defence across CTM.

What You’ll Do
• Build systems that are discoverable, composable, and controllable by AI agents
• Engineer scalable services that process and prioritise millions of operational and security signals
• Develop agent frameworks that allow safe, observable interaction between humans and AI
• Modernise legacy platforms to be compatible with autonomous detection and response
• Be a part of AI capabilities, Security Engineering, and Data teams to ensure alignment with CTM’s broader AI strategy

What You’ll Bring
We’re not expecting you to tick every box, if you’re excited about the role and feel you could grow into it, we’d love to hear from you.
• Strong skills in modern software development (e.g. Python, Go, Java, or TypeScript)
• Experience building secure, scalable systems, preferably in real-time or event-driven environments
• Curiosity about AI/ML, agent systems, or intelligent automation
• A passion for building safe, observable, and responsible technology
• Ability to collaborate across disciplines, learn quickly, and lead by example
You’ll be part of a forward-looking team that’s shaping the future of defence technology, building AI that defends, not deceives.

There’s something for everyone.
We’re a place of opportunity. You’ll have the tools and autonomy to drive your own career, supported by a team of amazingly talented people.
And then there’s our benefits. For us, it’s not just about a competitive salary and hybrid working, we care about what matters to you. From a generous holiday allowance and private healthcare to an electric car scheme and paid development, wellbeing and CSR days, we’ve pretty much got you covered!
