• Ensure code quality, maintainability, and performance through code reviews and mentoring.
• Contribute to DevOps pipelines and CI/CD practices in secure environments.
• Champion engineering best practices and continuous improvement within the team.

Essential:

• Active SC Clearance (or eligible and willing to undergo clearance).
• Strong Java and Spring Boot development experience.
• Proven experience delivering full-stack solutions (e.g. React, Angular, or Vue).
• Good knowledge of microservices, RESTful APIs, and containerisation (Docker/Kubernetes).
• Experience working with AWS or other cloud environments.
• Understanding of secure software design and deployment in government or defence contexts.
• Excellent communication, leadership, and mentoring skills.

Desirable:

• Experience with CI/CD pipelines (e.g. Jenkins, GitLab CI).
• Familiarity with infrastructure-as-code (Terraform, Ansible).
• Exposure to Agile and DevSecOps delivery models.

Why Apply?

• High-impact work on systems that directly support UK Government missions.
• Technical autonomy and input into architecture and design decisions.
• Collaborative culture with a focus on professional growth.
• Competitive salary and comprehensive benefits package.
