This is an exciting opportunity to play a key role in supporting the delivery of secure services that protect lives, the environment, and the UK's maritime interests.

As a Cyber Security Specialist, you will:

• Embed Secure by Design principles into projects and operational processes, working closely with internal teams and external partners.
• Identify and assess cyber risks , providing clear, contextualised advice to support informed decision-making and build cyber resilience.
• Provide pragmatic and proportionate security guidance across a range of technical and strategic issues, aligning with organisational and national priorities.
• Develop and deliver cyber security training to raise awareness and support a positive security culture across the agency.

You will be an effective communicator, able to build trusted relationships and influence a wide range of stakeholders. You'll combine strong technical knowledge with a collaborative approach, contributing to a secure, resilient operating environment.

This role offers the opportunity to help embed security in an innovative emergency services organisation where your work helps secure critical systems.

Your responsibilities include but are not limited to:

• Providing security consultation on projects, strategic programs, and procurement activities, defining cyber and technical controls inline with MCA policy, and ensuring Secure by Design principles are embedded.
