So are we. Join Compare the Market and help to make financial decision making a breeze for millions.

At Compare the Market, we're a purpose-driven business powered by tech and AI. We're building high-performing, results-driven teams with the skills, mindset, and ambition to deliver outcomes at pace. Every role here plays a part in driving our mission forward, and we create an environment where you can bring your authentic self, grow a truly characterful career, and see the direct impact of your work on the lives of our customers.

We've carved a meerkat-shaped niche and we're looking for ambitious, curious thinkers who thrive in a fast-moving, high-impact environment. If you love accountability, embrace challenge, and want to make a real difference, you'll fit right in.

What you'll be doing:

Help evolve our security capabilities as we continue our shift towards AI-enabled security engineering and automation.
Own and improve vulnerability management processes, helping identify, prioritise and drive remediation of security weaknesses across the business.
Build and support AI-powered workflows and agentic processes that improve how security issues are identified, investigated and resolved.
Explore emerging AI capabilities and identify practical opportunities to apply them across security and technology operations.
Work closely with engineering teams to support the secure adoption of AI technologies and automation across the organisation.
Build and maintain integrations between security, engineering and operational tooling to improve efficiency and reduce manual effort.
Coordinate external security testing activities, including penetration testing and bug bounty programmes, and work with teams to drive findings through to resolution.
Support security incident response, helping contain, investigate and resolve security incidents when they occur.
Use threat intelligence and security insights to help shape priorities and strengthen our overall security posture.
Partner with engineers, platform teams and technical leaders to embed security into technology delivery and improve security outcomes across the business.

What we're looking for:

Strong hands-on experience in security engineering, vulnerability management, cyber operations or a related security discipline.
Experience owning and driving remediation of security vulnerabilities rather than simply reporting on them.
An interest in AI and automation, with practical experience using technology to improve operational efficiency or engineering processes.
Experience working with APIs, integrations, workflows and automation tooling.
Strong scripting or programming capability, ideally with technologies such as Python, PowerShell or similar.
Experience coordinating and managing outcomes from penetration tests, bug bounty programmes or other security assessment activities.
Familiarity with cloud platforms and cloud security principles.
The ability to work across multiple teams and influence security outcomes outside of a traditional security silo.
Strong problem-solving skills and the ability to balance security risk with practical business outcomes.
A curious mindset, a willingness to challenge existing approaches, and a desire to help shape the future of AI-driven security engineering.
