• Engineer & Assure: Apply test-driven development and automated unit, integration, contract and end-to-end testing to deliver secure, maintainable software.
• Automate & Deploy: Develop CI/CD pipelines, infrastructure as code and deployment automation, supporting containerised services across Azure and Kubernetes.
• Optimise & Operate: Use monitoring, logs, metrics and traces to diagnose issues and improve performance, resilience and service operability.
• Collaborate & Influence: Work with Technical Leads, Architects, Product, Delivery, QA, DevOps and other suppliers to manage dependencies and deliver successful outcomes.
• Innovate & Improve: Use CGI-approved AI-assisted development tools where appropriate to enhance coding, testing, documentation and troubleshooting, with appropriate human oversight.
• Own & Resolve: Identify technical blockers and risks early, recommend pragmatic solutions and drive issues through to resolution.
• Guide & Support: Mentor developers, contribute to code reviews and technical discussions, and share reusable approaches across the engineering community.
• You'll be an experienced hands‑on Full Stack Developer with strong Java and Angular skills and a track record of delivering production‑quality solutions within complex environments.

• Full stack engineering: Strong hands‑on software development experience, including Java, Angular, Node.js and Express.js.
• Distributed architecture: Proven experience developing microservices, RESTful APIs, integrations and distributed systems.
• Data: Experience working with SQL databases, particularly PostgreSQL.
• Azure & Kubernetes: Experience with Azure cloud technologies, ideally including AKS, Azure Service Bus and Application Insights.
• DevOps & automation: Strong experience with CI/CD and tools such as Git, Jenkins and Terraform.
• Engineering quality: Demonstrable experience of automated testing, secure development and building maintainable, production‑quality software.
• Technical ownership: Proven ability to translate architecture and requirements into practical solutions and make pragmatic engineering decisions.
• Collaborative delivery: Ability to operate effectively across multidisciplinary and multi‑supplier teams while communicating risks, dependencies and trade‑offs clearly.
• AI-assisted engineering - desirable: Experience using tools such as Codex or GitHub Copilot to improve software engineering productivity and quality.
