The team is responsible for the delivery and support of production environments which are typically housed within Azure, as well as integrating software changes into the enterprise environment as part of ongoing project work. The role includes participation in an on-call rota to ensure coverage during business hours, with plans to expand support coverage as the business scales. Occasional weekend work may be required to support release testing and deployment activities.

DMI (Digital Markets Infrastructure) is an ambitious project: large-scale, complex and uses a range of blockchain architecture patterns, with numerous stakeholders (internal and external) and use cases.

• Implement, maintain, and optimise containerization for DMI services (e.g. via Docker).

• Automate infrastructure provisioning and scaling (e.g. Terraform).

• Integrate security protocols into the DevOps lifecycle, ensuring adaptability against vulnerabilities.

• Partner with software engineers, QA, and other teams to ensure efficient deployment, monitoring, and maintenance of applications.

• Keep up to date with the latest industry trends, tools, and guidelines in DevOps and cloud infrastructure.

What you'll bring:

• Computer science, software engineering, or relevant technical background required.

• 5 + years of professional experience in DevOps and infrastructure management.

• 5+ years of specific experience with Cloud platforms (AWS/Azure/GCP)

• Proficient in Kubernetes, Docker, and Terraform.

• Experience with the Azure cloud platform, handling workloads, provisioning & deployments.

• Deep knowledge of security standards in cloud and DevOps contexts.
