- Developing event-driven and microservices-based systems
- Supporting CI/CD and automated deployment pipelines
- Working closely with DevOps, platform and cloud engineering teams
- Supporting secure and resilient distributed systems
- Contributing to technical design, engineering standards and delivery quality
- Operating within Agile engineering teams delivering modern cloud-native services
Core skills required
- Strong Python engineering experience
- AWS cloud-native engineering
- REST APIs / backend services
- Microservices and event-driven architectures
- Terraform / Infrastructure as Code
- CI/CD pipelines
- Docker / containerisation
- Cloud integration experience
- GitHub Actions / GitLab CI / Jenkins
- Experience working within Agile engineering teams
Highly desirable
- FastAPI / Flask
- AWS Lambda / ECS / API Gateway
- SNS / SQS / EventBridge
- Kubernetes / EKS
- DevSecOps experience
- AI / LLM integration exposure
- Secure government or regulated environment experience
- SC, enhanced SC or DV clearance
Environment & culture
The engineering environment is modern, fast-moving and highly collaborative. The team work closely across software engineering, DevOps, platform engineering and automation functions, with strong focus around delivery quality, automation and cloud-native best practice.
Candidates with experience across government digital services, AWS-hosted platforms and modern DevOps engineering environments will align particularly well.
