• Manage the availability, allocation and stability of non-production environments, including SIT and UAT.

• Act as the key point of contact for environment planning, access and conflict resolution across delivery teams.

• Maintain a clear and auditable release process using tools such as Azure DevOps, Jira and Xray.

• Work closely with testing teams to ensure environments are appropriately configured and refreshed for planned test cycles.

• Create and maintain a central change and release schedule, ensuring risks, dependencies and constraints are effectively managed.

• Support Service Transition activities, including Hypercare and Early Life Support (ELS).

• Participate in PI Planning and Agile ceremonies to identify release risks, environment dependencies and delivery impacts.

• Facilitate Go/No-Go readiness assessments and support governance forums with release decision-making.

• Collaborate with third-party suppliers, programme teams and business stakeholders to ensure successful deployment outcomes.

• Proven experience managing releases, deployments and cutovers within large-scale transformation programmes.

• Experience creating and executing detailed Cutover Run Books.

• Strong Release Management and Environment Management expertise.

• Hands-on experience with Azure DevOps, Jira, Xray or similar DevOps toolsets.

• Experience managing environment contention across multiple teams and workstreams.

• Knowledge of ITIL Service Transition, Hypercare and Early Life Support models.

• Strong understanding of SAFe Agile and working within Agile delivery frameworks.

• Excellent stakeholder management skills with the ability to influence technical teams, suppliers and senior stakeholders.

• Strong organisational skills with the ability to manage competing priorities in a fast-paced programme environment.

• Experience within Utilities or other regulated industries would be advantageous.

• The opportunity to play a key role in a major Billing and CRM transformation programme.

• A high-profile position working alongside senior programme leadership, architects and delivery partners.

• Exposure to a complex enterprise-scale SAFe Agile environment.

• The chance to shape release, cutover and environment management processes that are critical to programme success.
