Job description

We are looking for a Senior DevOps Engineer to help build and maintain the infrastructure, tooling and processes that enable our engineering teams to deliver high- quality software quickly and reliably for our clients and internal processes.

You will work closely with our Software Engineers, as well as client tech teams, developing the full lifecycle of environments and CI/CD pipelines across multiple clouds (Azure, AWS and occasionally GCP) and our on-premise data centre. You will be instrumental in improving reliability and observability for the ADSP delivery team and our clients.

If this sounds like you, we can't wait to hear from you!

KEY RESPONSIBILITIES:

• Design, build and maintain infrastructure on Azure and AWS (and occasionally GCP) using infrastructure‑as‑code.
• Standardise and optimise Docker images for our Python and TypeScript services.
• Manage container runtimes and orchestration platforms (e.g. Docker Compose, Kubernetes, ECS, AKS, etc.).
• Implement image scanning, registry management and deployment strategies (blue/green, canary, rolling).
• Design and maintain CI/CD pipelines to build, test and deploy applications across environments.
• Integrate automated testing, security checks and quality gates into the pipelines.
• Automate repetitive operational tasks using scripts and tooling (Python, Bash, etc.).
• Collaborate with developers to define branching strategies, release processes and rollback procedures.
• Implement and maintain monitoring, logging and alerting for applications and infrastructure.
• Participate in incident response, root‑cause analysis and post‑incident reviews.
• Work with security and engineering teams to implement best practices for secrets management, access control and hardening of Linux, cloud resources and container images.
• Contribute to backup, disaster recovery and business continuity planning.
• Improve the local and remote development experience inside Linux VMs (tooling, environment consistency, documentation).
• Provide guidance and support to engineering teams on the use of Docker, cloud services and deployment tools effectively.
• Champion DevOps culture, promoting automation, observability and continuous improvement.
• Communicate with clients through written reports, calls and presentations to explain your work and recommendations.
• Work closely with client tech teams to understand their requirements, integrate with their existing tooling and processes, and design appropriate DevOps solutions.
• Support the handover of infrastructure, pipelines and operational runbooks to client teams, ensuring they can operate and evolve the solution.
• Represent the DevOps perspective in client workshops, discovery sessions and architecture/design reviews.

KEY REQUIREMENTS:

• Strong hands‑on experience with Linux (preferably in a server or VM context).
• Strong practical experience with Docker (creating, optimising and running containers in production).
• Experience with at least one major cloud provider (Azure or AWS) in a production environment; familiarity with the other and/or GCP is a plus.
• Experience designing and maintaining CI/CD pipelines (e.g. Azure DevOps, GitLab CI, GitHub Actions, CircleCI, Jenkins, etc.).
• Proficiency with at least one scripting or programming language (e.g. Python, Bash).
• Experience with infrastructure‑as‑code (e.g. Terraform, ARM/Bicep, CloudFormation, Pulumi).
• Understanding of networking fundamentals (DNS, routing, load balancing, VPNs, firewalls).
• Familiarity with monitoring and logging tools (e.g. Prometheus, Grafana, ELK/EFK stack, CloudWatch, Azure Monitor, Datadog, etc.).
• Good understanding of security best practices in cloud and Linux environments (IAM, least privilege, secrets management, patching).
• Experience presenting technical concepts to stakeholders.
• Ability to work independently and as part of a team
