Quantitative Systems Engineer (Software & Networks)

Do you love dissecting complex software behaviors, data pipelines, and network communications to evaluate how resiliently a system actually performs?

Are you searching for critical, high-impact technical work within strategic deterrence and national defense?

Do you like contributing to multidisciplinary engineering teams where analytical rigor directly drives architecture decisions?, * Your primary responsibility will be to perform rigorous technical design analysis of complex, software-intensive architectures, evaluating system-level data flows, protocol latency, failover mechanisms, and network survivability.

• You will construct and interrogate structural and behavioral system models in Cameo/MagicDraw to evaluate architectural logic, software interface boundaries, and data exchanges.
• You will conduct quantitative trade studies and vulnerability assessments to identify performance bottlenecks, integration friction, and resilience risks early in the development lifecycle.
• You will collaborate with multi-specialty engineering teams to translate analytical findings into actionable architectural improvements, communicating results directly to program sponsors and system contractors.

• Possess a BS in Software Engineering, Computer Science, Computer Engineering, Network Engineering, or a closely related technical discipline.
• Have 2+ years of relevant experience executing quantitative: software design analysis, network topology evaluation, or digital system architectural analysis.
• Are skilled in evaluating system interfaces, data pipelines, and distributed communications through quantitative modeling or architectural simulation.
• Have a working knowledge of Systems Engineering fundamentals and some familiarity using Model-Based Systems Engineering (MBSE) tools, such as Cameo Enterprise Architect / MagicDraw (SysML).
• Are willing and able to travel periodically (approximately 5-10%), including local visits to sponsor offices and trips to contractor or military test facilities.
• Hold an active Secret security clearance and are able to get a Top Secret clearance. If selected, you will be subject to a government security clearance investigation and must meet the requirements for access to classified information. Eligibility requirements include U.S. citizenship.

You’ll go above and beyond our minimum requirements if you…

• Have 5+ years of professional experience executing design analysis.
• Have an MS in Software Engineering, Computer Engineering, or a technical discipline with sustained hands-on focus in technical design analysis.
• Hold an active Top Secret security clearance or TS/SCI.
• Have direct experience evaluating software assurance, anti-tamper, or cyber resilience within DoD weapon systems or secure communications architectures.
• Have familiarity with defense acquisition programs, particularly Navy Strategic Systems Programs (SSP) or Air Force nuclear deterrence programs.
