The Long Range Radars Department within Systems Engineering & Test Capabilities (SE&TC) is seeking a Lead Systems Engineer for the new X-Band Transportable Radar-2 program (XTR-2). This role is a key leadership position within the program, which serves as the system design focal point and acts as the principal arbiter of system requirements and performance. As the Lead Systems Engineer, you will apply systems thinking and leverage your technical expertise to shape initial concepts into optimized system designs that balance performance, cost, and schedule objectives. In close collaboration with the Office of the Chief Engineer (OCE), you will ensure technical integrity, mission alignment, and seamless execution across program teams.

The Long Range Radars department specializes in delivering world‑class missile defense and sensor systems through expertise in concept development, architectural design, requirements generation and flow‑down, modeling and simulation, systems analysis, integration, testing, and evaluation. Our success is driven by the dedication of our people, robust processes and advanced technology.

What You Will Do

As the Lead Systems Engineer, you will be a key architect of the XTR-2 program’s success by defining, analyzing, and leading the system’s technical baseline. Your leadership will drive system performance, risk management, and cross-disciplinary integration to achieve a high-performing, coherent design. Key responsibilities include:

• Maintain accountability for the system requirements baseline

• Allocate and manage system performance margins across all subsystems

• Develop and lead the execution of the system modeling and simulation plan

• Assess and clearly communicate performance impacts associated with technical risks

• Conduct system‑level trades to ensure allocated system and subsystem performance requirements are met

• Drive consistency and coherence of the system design across IPTs, CPTs, and key stakeholders

• Ensure robust systems engineering representation on applicable engineering boards to uphold technical rigor and mission alignment.

• Partner with the Program Office to ensure the engineering team aligns with program cost, schedule, and technical objectives.

• This role can be based out of Woburn, MA or Huntsville, AL. 

Qualifications You Must Have

• Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and a minimum of 10 years of prior relevant experience.

• Experience leading systems engineering teams and initiatives.

• Experience in requirements development within DoD programs.

Qualifications We Prefer

• Advanced degree in a relevant field.

• Professional experience in the aerospace/defense industry, particularly with missile defense systems and tracking radar sensors.

• Demonstrated expertise in Model-Based Systems Engineering (MBSE) and familiarity with tools such as
