Clearance Required: Active UK Developed Vetting (DV)
We’re hiring on behalf of a specialist consultancy supporting secure, high-impact projects in the defence and national security space. As a Senior Software Engineer with current DV clearance, you’ll be working on mission-critical systems that help protect the UK’s interests at home and abroad.
This is a hybrid role based in Cheltenham, typically requiring two to three days on site each week.
You’ll be developing robust, secure software using Java or modern C++ in complex, high-assurance environments. Projects may involve real-time data processing, high-throughput back-end systems, or secure mission planning platforms. The work spans the full development lifecycle, and you’ll collaborate closely with DevOps engineers, security architects and fellow developers to deliver reliable solutions in classified settings.
You must hold active DV clearance and have strong experience with Java or C++. A background in Linux development, secure software design, and working with modern tooling such as GitLab, Jenkins, Docker or Kubernetes is important. Familiarity with microservice architecture, REST APIs, and agile delivery will be helpful.
Experience in defence, intelligence or other classified domains is highly valued. Exposure to Spring Boot, Boost, air-gapped environments, or infrastructure-as-code tools like Ansible or Terraform would be a bonus.
In return, you’ll join a highly skilled technical team, gain access to DV-only projects and communities, and benefit from a supportive culture, a generous package, and clear opportunities for career progression.
