• Develop and maintain CI/CD pipelines, Git Ops workflows and automated deployment approaches using tools such as ArgoCD.
• Implement and improve observability using Prometheus, Grafana, logging and alerting to support resilient platform operations.
• Use infrastructure-as-code and platform automation with Helm, Go and Terraform to deliver repeatable, assured environments.
• Mentor engineers, review technical approaches and help teams adopt modern Dev Ops and platform engineering practices.
• Lead and contribute to agile ceremonies, keeping delivery aligned to user needs, operational constraints and security expectations.

• Strong Dev Ops or infrastructure engineering background, with experience leading technical teams.
• Experience delivering secure cloud-based infrastructure and services, alongside on-premise platform environments.
• Infrastructure-as-code experience using Terraform and Helm, with automation or tooling development using Go.
• Container and orchestration experience with Docker, Kubernetes, Helm and related deployment tooling.
• CI/CD and Git Ops tooling experience, ideally including ArgoCD and automated deployment pipelines.
• Good understanding of observability, monitoring and alerting using tools such as Prometheus and Grafana, alongside security, networking, logging, secrets management and operational assurance.
• Able to learn new technologies quickly and help others adopt them safely and effectively.

You’ll work with smart, supportive people on projects that genuinely matter, in an environment that values technical excellence, collaboration and continuous learning. We invest in your growth, value diverse thinking and offer flexible working alongside a strong benefits package (including 30 days’ holiday plus bank holidays).
