The Opportunity
We're supporting Pennon Water Services on the delivery of the Nexus Transformation Programme, a major business and technology transformation focused on modernising Billing and CRM platforms.
We are looking for an experienced Change, Release & Environment Manager to take ownership of release planning, environment management and service transition activities across this complex programme. Working within a SAFe Agile delivery framework, you'll play a critical role in ensuring releases are delivered in a controlled and predictable manner, environments remain stable, and the transition into live operation is successful.
This is an excellent opportunity for a release and environment management professional who thrives in large-scale transformation programmes and is confident working across technical teams, third-party suppliers and senior stakeholders.
Key Responsibilities
- Coordinate the end-to-end release life-cycle, ensuring deployments are planned, scheduled and delivered in line with programme milestones.
- Develop and manage detailed Cutover Run Books, overseeing activities required for system releases and data transitions.
- 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.
