Who Are We Looking to Add to Our Team?

Working closely with Programme Leads, delivery teams, and senior client stakeholders, you’ll bring structure, governance, and strategic oversight to every engagement.

This role goes beyond project coordination — you’ll own account-level delivery outcomes, contribute to commercial success, mentor junior team members, and help shape how Massive Rocket delivers scalable, high-quality programmes globally.
