You'll work across the full software development lifecycle, collaborating closely with engineers, architects, and stakeholders to deliver robust solutions.

We're open to engineers with different backgrounds and levels of experience – what matters most is strong engineering fundamentals, curiosity, and a willingness to learn.

• Collaborate within agile teams to deliver secure and reliable solutions
• Work with modern cloud and containerised environments

• Java, Python, JavaScript, TypeScript
• Angular, React, Vue
• Docker, Kubernetes
• AWS and/or Azure
• MERN stack
• Elasticsearch, Neo4J

We value engineers who are open‑minded, adaptable, and keen to learn new technologies as project needs evolve.

Security & Location

• You must be a UK citizen and have lived in the UK for the past 10 years
• You must already hold high‑level UK security clearance
• Customer sites are based in Gloucestershire, Manchester, and London, so you must be willing to travel to one of these locations

Benefits

• Salary band: £40,000-75,000, depending on experience (we may consider more junior or more senior outside this range for the right candidate)
• 10% clearance bonus
• 25 days annual leave plus bank holidays
• Buy or sell up to 5 days leave per year
• 8% employer pension contribution
• BUPA health cover
• Life cover of 4× salary
• EV car scheme via salary sacrifice

• Flexible working and flexi‑time
• 10 days per year training allowance

Every employee has an individual training and career development plan. We recognise that everyone learns differently and we actively support long‑term growth.

Our Process

We keep things straightforward and human:

• A 30‑minute introductory chat with our recruiter, Sarah
• A 1‑hour Microsoft Teams interview or on‑site interview with two members of the team
• An informal conversation with two of our Founders

We believe open, organic conversations are the best way for both sides to decide if the role is the right fit.
