IT Systems Manager

IT Systems & Compliance Administrator

About the Role

The IT Systems & Compliance Administrator will serve as the primary on-the-ground IT resource for Advanced Navigation's US facility. This is a hands-on, multi-disciplinary role that bridges day-to-day IT operations with the company's defense sector compliance objectives, most notably its work towards Cybersecurity Maturity Model Certification (CMMC) Level 2 and the development of the company's System Security Plan (SSP).

The successful candidate will act as the Key System Administrator for a suite of enterprise platforms, manage relationships with external IT vendors, and serve as a key liaison between the US operation and the global IT function.

While deep technical specialization is not a prerequisite, the role demands solid foundational knowledge across core IT disciplines and a proven ability to operate within rigorous compliance frameworks. This will initially be a very hands-on role, and we are looking for someone who is willing to grow with it as the US operation scales. The scope and seniority of the position are expected to expand as the business matures.
