Senior DevSecOps Engineer for Defence & Secure CI/CD

Lever; City of Westminster; On-site; GBP 90,000 - 130,000; Full time

Job summary

Shield AI seeks a DevSecOps Engineer to design, build, secure, and operate the software delivery infrastructure for defence autonomous systems. This role sits at the intersection of software engineering, platform engineering, cyber security, and defence systems engineering.

You will embed security throughout the software lifecycle, implement automated security controls in CI/CD, and work with cross-disciplinary teams to meet defence security requirements and MOD Secure by Design principles.

Qualifications

• BS or MS in Computer Science, Software Engineering, Cyber Security, Electrical Engineering, Systems Engineering, or a related technical discipline, or equivalent practical experience.
• 5+ years of experience in DevOps, DevSecOps, platform engineering, site reliability engineering, software engineering, or a related technical discipline.
• Significant experience delivering software or digital capabilities within UK defence or another highly regulated national security environment.
• Strong understanding of the UK Ministry of Defence/NATO approach to DevSecOps and Secure by Design, including the integration of cyber security and risk management throughout the capability lifecycle.
• Experience applying MOD security policies, security assurance processes, and technical security requirements to software intensive defence programmes.
• Experience developing and operating CI/CD pipelines using modern source control, build, test, artefact management, and deployment technologies.

Responsibilities

• Design, build, and operate secure development and deployment infrastructure for Shield AI autonomy and defence programmes.
• Develop and maintain CI/CD pipelines that enable rapid, repeatable, and secure delivery of autonomy and mission software.
• Embed security throughout the software development lifecycle, ensuring security controls, testing, evidence, and assurance are integrated into engineering workflows rather than treated as separate activities.
• Apply UK MOD Secure by Design principles throughout the development lifecycle and help engineering teams understand and meet their responsibilities for cyber security and technical assurance.
• Work closely with software, autonomy, systems, cyber security, integration, and test engineers to establish development environments that support rapid engineering while meeting defence security requirements.
• Design and maintain development and deployment environments spanning cloud, on premises infrastructure, laboratory environments, simulation, hardware in the loop, and operational platforms.
• Enable secure software development and deployment across different security classifications and appropriately segmented development environments.
• Implement automated security controls within CI/CD pipelines, including static analysis, dependency scanning, container scanning, secrets detection, software composition analysis, vulnerability management, and policy enforcement.
• Champion a DevSecOps culture where software engineers take ownership of the security, reliability, deployability, and operational performance of the systems they develop.
