Hybrid: Hybrid working across secure sites and collaborative engineering environments
Salary: Competitive salary aligned to experience and clearance level
Clearance: Active UK*C DV clearance required
The Opportunity
This is the kind of environment that tends to attract engineers who want to stay close to meaningful technical work without becoming constrained by heavily layered delivery structures or narrow ownership boundaries.
The work sits across the UK National Security and Intelligence ecosystem, supporting operational systems used within highly secure, high-side environments where reliability, adaptability and engineering quality matter. Programmes are long-term and mission-focused, but teams still retain the flexibility and engineering autonomy typically associated with smaller, engineering-led organisations.
What often appeals to experienced engineers is the level of exposure. Rather than being isolated to a single layer of the stack or a tightly defined delivery function, engineers here tend to work closely with users, technical leadership and multidisciplinary teams across the wider software lifecycle. There is genuine opportunity to influence how systems evolve, contribute ideas early and build a broader understanding of operational capability.
The culture is collaborative, low-ego and technically grounded. Teams value pragmatic engineering, modern software practices and people who are comfortable solving problems collectively rather than simply delivering against tickets. For engineers who enjoy ownership, project variety and working across all compass points of secure delivery, it is the kind of environment that can offer strong long-term development without losing technical depth.
The Role
You'll be joining an agile engineering team responsible for designing, building and improving secure software systems used within operational National Security environments.
The role combines hands-on full stack engineering with close collaboration across users, engineers and stakeholders, making it well suited to somebody who enjoys solving technical problems while understanding the wider operational context behind the systems they are building.
Teams work iteratively and collaboratively, with engineers contributing throughout the delivery lifecycle from early design discussions through to implementation, testing and ongoing improvement of live capability.
