Why this role?

Looking to move beyond pure software engineering or support into something more impactful?

This is a chance to work on mission-critical national security systems, combining software engineering with real-world problem solving. You’ll be the person who keeps things running, fixes what breaks, and improves systems so they don’t break again.

This role would suit:

• Software engineers wanting a more operational / DevOps-focused role
• 2nd / 3rd line support engineers looking to step up into engineering

What you’ll be doing

• Troubleshooting and fixing live application issues in secure environments
• Supporting and improving critical systems used in national security
• Automating manual processes (less firefighting, more engineering)
• Working closely with engineers to build more reliable, scalable platforms
• Improving monitoring, observability, and system performance
• Taking part in a shared on-call rota

This role typically sits at around a 50/50 split between support and engineering, with a strong focus on increasing automation over time.

What they’re looking for

• Background in software engineering OR strong support (2nd/3rd line)
• Experience with Java, JavaScript, or other web technologies
• Knowledge of Linux or Windows (Bash / PowerShell)
• Exposure to cloud platforms (AWS, Azure, or similar)
• Understanding of databases (MongoDB, Elasticsearch etc.)
• Interest in automation, DevOps, or SRE principles

Nice to have:

• Docker or microservices experience
• Monitoring tools (ELK stack etc.)
• Agile / Scrum experience

Why join?

• Work on high-impact, real-world national security projects
• Clear pathway into DevOps / SRE / platform engineering
• Strong learning and development support
• Collaborative, engineering-led environment
• Hybrid working and excellent benefits
