In this role, you will take ownership of product security delivery, working closely with multidisciplinary product teams across the EW and FCA business areas to ensure security is embedded throughout the lifecycle. This role is hybrid; a minimum of one day per week on site is required. Work from any of our sites: Luton, Bristol, Southampton, Lincoln or Basildon.

Responsibilities

• Develop and manage security protocols, tools, and processes that keep our technologies ahead of emerging threats.
• Creation and management of key artefacts such as Risk Assessments and Remediation Action Plans.
• Drive Security Assurance through the full product lifecycle, ensuring every design is robust, compliant, and resilient.
• Contribute to continual improvement of the engineering capability.
• Contribute to Leonardo's UK‑wide Security and IA community – shaping best practice and influencing security strategy.

What you'll bring

• Practical experience of ISO27001/27004/27005 and NIST Risk Management Framework (RMF).
• Experience supporting a security risk management system for highly regulated products based on recognised frameworks such as aerospace, nuclear, automotive, rail or oil and gas.
• Understanding and appreciation of the Engineering development lifecycles and how product security aligns.
• Ability to interpret Penetration Test Reports and support remediation action.
• Aware of UK Government Assurance Processes (e.g., legacy JSP 604 Assurance or the CAF GovAssure processes).

This is not an exhaustive list, and we are keen to hear from you even if you might not have experience in all of the above. The most important skill is a good attitude and willingness to learn.
