Trellix Endpoint Engineer

D2 Technical Services is looking for a Senior Endpoint Security Engineer who's ready to do work that actually matters. You'll be embedded with our team supporting the National Geospatial-Intelligence Agency (NGA) — one of the Intelligence Community's most critical GEOINT missions. This is a long-term, stable contract meaning you get the stability of a large program with the agility of a specialized team.

If you're the kind of engineer who takes pride in building airtight security architectures, staying ahead of threats, and owning enterprise-level endpoint solutions — this role was built for you.

You won't be a cog in a machine here. You'll be a key voice in shaping how endpoint security is designed, deployed, and sustained across a large-scale enterprise environment:

Architect and enforce security configurations that protect networks, devices, and data from real-world threats

Lead engineering and sustainment of enterprise Trellix endpoint security solutions (ENS, DLP, Policy Auditor, FIM, Application Whitelisting)

Drive security infrastructure from design through implementation — including system configuration, standards documentation, and policy management

Partner directly with software vendors and the customer to research and roll out enterprise-wide security enhancements

Own incident investigation and reporting, and lead the charge on corrective action

Advise senior leadership and customers with clear, actionable status reports and security assessments
