Job description

We’re growing our Gloucester team and have several opportunities for Software Engineers to work across our Defence, Cyber and Intelligence programmes.

You’ll help create and improve secure software systems and applications that safeguard digital infrastructure across the UK. You may already specialise in a particular area, or you may enjoy working across several parts of software development - either is welcome.

This is a junior role, so we’re looking for a foundation in software development, a willingness to learn, and a desire to write well‑engineered, reliable, and maintainable software. We don’t expect you to arrive knowing every technology we use, we welcome people with curiosity, a passion for learning, and a commitment to continuous improvement. You’ll have opportunities to develop your technical skills, gain experience across a range of technologies, and grow with the support of experienced colleagues.

You’ll work alongside experienced colleagues and our customers to understand requirements and help deliver well‑engineered technical solutions.

Depending on your strengths and interests, you could specialise in one area or gain experience across several parts of the development lifecycle. Your work may include:

• Supporting the design, development, testing, debugging and documentation of software throughout its lifecycle.
• Investigating issues and contributing to improvements in the reliability, security and maintainability of our systems.
• Learning and applying modern software delivery practices, including infrastructure as code, CI/CD and test automation.
• Participating in technical discussions, code reviews and collaborative problem‑solving with colleagues.
• Learning from and working closely with experienced team members to develop your technical and professional skills.

Security clearance

This role requires you to be able to obtain and maintain eDV security clearance.

You don’t need to hold eDV clearance when you apply. If you don’t currently have it, we’ll support you through the application process.

Learning and development

You’ll have access to internal training and development, education‑assistance programmes and reimbursement for relevant professional memberships. We’ll help you build familiarity with our projects and technologies while giving you opportunities to deepen your existing strengths.

Required skills, qualifications and experience

• Experience delivering software in a professional engineering environment.
• Experience using Linux, Git and automated unit testing.
• The ability to evaluate different approaches to a technical problem and discuss the advantages and disadvantages of each.
• A collaborative approach and a dedication to continuous learning and team improvement.
• We want to hear about what excites you about software development, examples of projects you've worked on, and how you've developed your skills and knowledge.

Desired Skills:

• Cloud platforms, particularly AWS.
• Automated GitLab delivery pipelines and infrastructure as code.
• Microservices, serverless architectures and cloud migration.
• Relational and NoSQL databases, data integration and search technologies.
• Web and application frameworks such as React, Express and Next.js
• Tools including Gitlab, NiFi, Elasticsearch, Kibana, Jira and Confluence
• AI coding assistants, agentic coding and ML tooling

Knowledge in some of these areas is advantageous, but this is not a checklist, and we don’t expect one person to know them all. We’ll support you in learning new project‑specific technologies, including opportunities to explore practical uses of AI within software development.

Professional certifications are welcome - we’d love to know what qualifications you can bring to the team - but they aren’t essential.
