About the Job

Requirements

  • Possess a Bachelor of Science in Software Engineering, Computer Science, Computer Engineering, Network Engineering, or a closely related technical discipline.
  • Have at least 2 years of relevant experience executing quantitative software design analysis, network topology evaluation, or digital system architectural analysis.
  • Be skilled in evaluating system interfaces, data pipelines, and distributed communications through quantitative modeling or architectural simulation.
  • Have working knowledge of Systems Engineering fundamentals and some familiarity using Model-Based Systems Engineering tools such as Cameo Enterprise Architect or MagicDraw (SysML).
  • Be 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 be able to obtain a Top Secret clearance; eligibility for classified access requires U.S. citizenship.

Responsibilities

  • Perform rigorous technical design analysis of complex, software-intensive architectures, evaluating system-level data flows, protocol latency, failover mechanisms, and network survivability.
  • Construct and interrogate structural and behavioral system models in Cameo/MagicDraw to evaluate architectural logic, software interface boundaries, and data exchanges.
  • Conduct quantitative trade studies and vulnerability assessments to identify performance bottlenecks, integration friction, and resilience risks early in the development lifecycle.
  • Collaborate with multi-specialty engineering teams to translate analytical findings into actionable architectural improvements, communicating results directly to program sponsors and system contractors.

Desired Qualifications

  • Have at least 5 years of professional experience executing design analysis.
  • Have a Master of Science 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.

About the Company

Johns Hopkins Applied Physics Laboratory

Not-for-profit UARC delivering national security research

Johns Hopkins Applied Physics Laboratory (APL) is a not-for-profit university-affiliated research center that provides solutions to complex national security and scientific challenges through technical expertise, prototyping, research and development, and analysis. It uses engineering, simulations, and studies to design prototypes and deliver analyses that support government and partner organizations. Unlike many commercial firms, APL operates as a non-profit affiliated with Johns Hopkins and focuses on mission-oriented research rather than selling finished products. Its goal is to provide practical, thoroughly tested solutions to public-sector customers by performing research, developing prototypes, and offering expert analysis.
