• Experience working outside of a digital agency, ideally within an internal product team
• Knowledge of Umbraco Cloud, CI/CD pipelines, and automated deployments

• Demonstrated ability to manage offshore teams or coordinate distributed delivery
• Excellent communicator, able to work cross-functionally with design, infrastructure, and product teams
• Experience owning technical projects from requirements gathering through to release

• Exposure to containerisation (Docker/Kubernetes)
• Experience integrating with third-party APIs and services
• Familiarity with DevOps culture or Agile/Scrum environments
