Systems Engineer 3

***At Wyetech, you’ll be at the center of an award-winning corporate culture, breaking technological barriers and solving real-world problems for our federal government customers. We are committed to hiring the best of the best, and in return, we offer a world-class, truly unique employee experience that is rare within our industry.*** The Senior Systems Engineer (Level 3) serves as a principal technical leader and subject matter expert within the National Security Agency’s Enterprise Endpoint Detection and Response (EDR) Program. Operating in a highly classified, multidomain infrastructure, the successful candidate will drive the strategic architectural design, end-to-end integration, deployment, and optimization of premier endpoint security platforms, specifically Microsoft Defender for Endpoint (MDE) and Trellix HX. This critical role bridges high-level systems architecture with operational defense capabilities, ensuring total endpoint visibility, robust threat containment, and resilient configuration management across all enterprise and mission critical assets to defend national security infrastructure against sophisticated cyber threats. The Systems Engineer 3 is responsible for leading the lifecycle engineering and scale-out architecture of MDE and Trellix HX across hybrid environments, including on-premises, cloud, and virtual desktop infrastructures (VDI). This includes authoring complex system engineering and implementation plans, tuning agent configurations and exclusion policies to eliminate mission friction, and monitoring overall endpoint health at scale. The engineer will collaborate closely with threat hunting and intelligence analysts to translate actionable threat intelligence into custom technical indicators of compromise (IOCs), utilizing Kusto Query Language (KQL) and YARA rules. Additionally, the individual will act as a primary technical advisor to Government stakeholders on system risks and engineering considerations, provide advanced forensic support to the SOC during critical high-priority incidents, and actively mentor junior and mid-level engineering personnel within the program. ***Due to federal contract requirements, United States Citizenship and position appropriate security clearance is required. (e.g. Active TS/SCI security clearance with agency appropriate polygraph).*** ### Capabilities - Manage system requirements and derived requirements to ensure the delivery of production systems that are compatible with the defined system architecture(s) — Department of Defense Architecture Framework (DoDAF), Service-oriented Architecture (SOA), etc. - Contribute to the development of sections of systems engineering documentation such as System Engineering Plans, Initial Capabilities Documents, Requirements specifications, and Interface Control Documents - Assist with the development of system requirements, functional requirements, and allocation of the same to individual hardware, software, facility, and personnel components - Coordinate the resolution of action items from Configuration Control Board (CCB) meetings, design reviews, program reviews, and test reviews that require cross-discipline coordination - Participate in an Integrated Product Team to design new capabilities based upon evaluation of all necessary development and operational considerations - Allocate real-time process budgets and error budgets to systems and subsystem components - Generate alternative system concepts, physical architectures, and design solutions - Define the methods, processes, and evaluation criteria by which the systems, subsystems and work products are verified against their requirements in a written plan - Develop system design solution that satisfies the system requirements and fulfills the functional analysis - Review and provide input to program and contract work breakdown structure (WBS), work packages and the integrated master plan (IMP) - Participate in the development of system engineering documentation, su…
