Job description

An innovative space technology organisation developing next-generation robotic and autonomous systems for lunar and planetary exploration is seeking a Senior IT Security Engineer – Mission Systems Cybersecurity & Compliance. This individual will be responsible for securing mission-critical systems, ensuring cybersecurity compliance across complex engineering environments, and supporting the development of resilient operational infrastructure. The role combines technical cybersecurity expertise, governance and compliance leadership, and collaboration with multidisciplinary engineering teams in a fast-paced, high-growth environment.

Key Responsibilities

• Develop, implement, and maintain cybersecurity controls aligned with frameworks such as NIST 800-53, NIST 800-171, DFARS/FAR, and ITAR requirements.
• Translate cybersecurity requirements into system architecture, design, implementation, testing, and verification activities.
• Design and maintain security controls for mission and operational systems, including access management, continuous monitoring, vulnerability management, and incident response.
• Lead compliance initiatives, audits, and assessments while ensuring audit readiness and timely remediation of findings.
• Produce and maintain cybersecurity documentation including System Security Plans (SSPs), Plans of Action & Milestones (POA&Ms), Security Control Traceability Matrices (SCTMs), and supporting accreditation artefacts.
• Support security investigations, forensic analysis, monitoring activities, and remediation efforts for identified vulnerabilities and incidents.
• Evaluate and implement cybersecurity technologies such as SIEM, DLP, monitoring, and compliance management tools.
• Collaborate with engineering, IT, and compliance teams to strengthen governance, risk, and compliance (GRC) processes.
• Develop strategies to improve system resilience, survivability, maintainability, and security throughout the system lifecycle.
• Promote cybersecurity awareness and best practices across the organisation.

Key Requirements

• Bachelor's or Master's degree in Cybersecurity, Computer Science, Engineering, Information Technology, or a related discipline (or equivalent experience).
• Experience in cybersecurity, governance, risk management, compliance, or information assurance environments.
• Strong knowledge of cybersecurity frameworks and regulatory requirements including NIST, RMF, ISO standards, DFARS/FAR, and controlled environments.
• Experience supporting security compliance audits and accreditation activities.
• Understanding of systems engineering principles including requirements management, architecture, design, testing, and verification.
• Technical expertise across cloud environments, operating systems, networking, security controls, vulnerability management, and incident response.
• Experience developing and maintaining security documentation and compliance artefacts.
• Strong communication, stakeholder management, and cross-functional collaboration skills.
• Ability to work independently, manage competing priorities, and meet critical deadlines.
• Eligibility to work within regulated or government-controlled environments.

This is an excellent opportunity for a cybersecurity professional seeking to play a key role in protecting mission-critical systems within a cutting-edge aerospace and advanced technology environment. The successful candidate will contribute directly to the security, compliance, and resilience of systems supporting pioneering space exploration initiatives while working alongside highly skilled engineering and technical teams.
