About the Role

identify and monitor risks and dependencies, and take ownership of assigned activities and workstreams to ensure they continue progressing towards agreed transition milestones.

Importantly, the role is focused on enabling transition outcomes and strengthening delivery across the SPO. You will work closely with the Transition Lead as a capable second-in-command, helping coordinate work, support engineering and sustainment activities and independently progress assigned workstreams.
