Key Responsibilities:

Own and deliver engineering platform capabilities that facilitate building, testing, securing, and deploying services in a highly automated, CI/CD-driven environment.
Design, implement, and evolve CI/CD pipelines, ensuring consistent, reliable, and repeatable delivery processes across multiple teams and services.
Embed Infrastructure-as-Code (IaC) practices to drive standardisation and scalability.
Integrate security controls into engineering workflows, ensuring services are secure by design.
Support and enable engineering teams by providing guidance, tooling, and best practices.
Continuously optimise automation, identifying opportunities to remove repetitive manual tasks and improve the developer experience.
Collaborate across development, security, and operations to promote end-to-end ownership of services.
Maintain and improve engineering tooling and platforms, including source-code control systems, build systems, artifact repositories, and deployment frameworks.

Job Requirements:

Proficiency in software application development using languages such as Java, Python, JavaScript, C++, or C#.
Experience with database technologies (e.g., Elastic, MySQL, SQL*Server).
Understanding of CI/CD platforms (e.g., GitLab, Jenkins) and source-code control (e.g., Git, GitOps).
Knowledge of infrastructure management frameworks (e.g., Terraform, Ansible, Chef).
Familiarity with containerisation platforms (e.g., Kubernetes, Helm).
Experience with cloud-native platforms (e.g., AWS, Azure, GCP).
Ability to integrate security controls into engineering workflows.
Understanding of software and system validation, and test principles.

Benefits:

Opportunity to work on significant and challenging projects within the Defence & Security sector.
Access to cutting-edge tools and infrastructure in a technology-first environment.
Professional development and training opportunities.
A collaborative and mission-focused work atmosphere.
If you are an experienced Software Developer looking for an opportunity to contribute to national security and work with state-of-the-art technology, we encourage you to apply now. Join our client's dynamic team and make a meaningful impact in the Defence & Security sector
