Primary purpose of the position

The SPOC Engineer is responsible for the Secure Payload Operations Center and daily operations of the payloads and associated ground stations.

The Inmarsat Government SPOC is a highly automated environment, and the emphasis of the SPOC Payload Controller function is based on supervision of executing automated procedures rather than in their manual execution. However, comprehension and understanding of what each script is executing for both space and ground components is still critical.

The SPOC Engineer is expected to exercise all operations in a professional and disciplined manner, executing routine procedures to the letter.
