Description

Curious about what’s next?

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

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.

Why Compare the Market?

We’re a business built for pace and performance. Here, you’ll be encouraged to think differently, act boldly, and deliver brilliantly in a culture that values results and rewards progress.  

We believe diverse teams make better decisions, and we’re committed to creating an inclusive workplace where everyone feels empowered to grow, contribute, and thrive.
