So, you want to work from home? Let's be honest, remote work is not always all it's cut out to be. At G2 Ops, we offer a flexible schedule to meet the needs of our team members and customers. Due to the classification level of the projects we support as a Defense Contractor, we cannot offer fully remote opportunities at this time. You will have a shiny desk at our G2 Ops office and the ability to telework with prior approval.

We’ve worked hard to create a great culture where our team gets to come to a collaborative, exciting office environment, and we want you to join the fun!

Lastly, as we are working for the DoD, we are beholden to some requirements. The ideal candidate would already possess an active DoD Secret level clearance.
