Responsibilities:
* Perform product risk assessments and identify vulnerabilities across platforms.
* Collaborate with developers to integrate secure coding practices from the start.
* Lead threat modelling exercises and develop mitigation strategies.

* Ensure products meet key regulatory standards (ISO 27001, NIST 800 series, JSPs, Def Stans).
* Author security documentation, including RMADS and Security Assurance Documents.
* Perform penetration testing and coordinate remediation efforts.
Qualifications:
* Solid understanding of security frameworks such as ISO 27001/2, ISO 31000, NIST 800-30/37/53.
* Hands-on experience with Defence Standards (JSPs, HMG, Def Stan 05-138/139).
* Strong knowledge of security testing tools and techniques.
* Excellent communication skills to explain complex risks and solutions clearly.
* Proactive problem-solving mindset with high integrity and professional ethics.
* Experience with NIST standards (this is an absolute requirement).
Ideal Candidate Traits:
* Enjoy solving complex problems with innovative, practical solutions.
* Communicate clearly, confidently, and empathetically.
* Driven by quality, attention to detail, and delivering secure products exceeding expectations.
* Adapt well under pressure and thrive in fast-paced, multidisciplinary environments.
This role reports directly to the Head of Product Security and offers an excellent opportunity to impact critical technology projects. If you’re ready to help shape secure and resilient systems, we’d love to hear from you.
