Orbis Operations is a technology company that delivers sovereign intelligence and decision capabilities to the United States Government and its allies. We convert complex information and operational systems into decisive outcomes, giving public institutions and critical enterprises the tools to move faster, see clearer, and act first in an increasingly contested world.

We are not a consulting firm and not a systems integrator. Every Orbis team is built around practitioners who have operated at the mission edge, and every engagement is judged on one thing: whether it produces working capability, not slide decks. Solutions forged from experience — that is how we build, and it is how we hire.

Orbis is seeking a Senior Network Engineer to join our team based in Canberra, Australia, supporting mission-critical network infrastructure for government and allied defense customers. This role will design, deploy, and sustain secure, high-availability networks across classified and multi-domain environments — including on-premises, cloud, and contested/disconnected edge deployments — in direct support of customer and Orbis’ data and decision platforms. You will work alongside practitioners who have operated at the mission edge, with direct responsibility for the network backbone that Orbis’ governed data fabric runs on.

This role is based in Canberra, Australian Capital Territory, with an on-site presence required to support classified network infrastructure and customer facilities. Some domestic and international travel may be required to support program and customer needs.
