Senior Performance Analysis Engineer – Ground-based Missile Defense

APEX TK is looking for an experienced, team-oriented Performance Analyst Engineer to join our Huntsville, AL team. In this role you will support the analysis and assessment of Ground-based Missile Defense (GMD) systems in support of Missile Defense Agency (MDA). The successful candidate will perform mission and system performance analyses to evaluate weapon system effectiveness, engagement performance, and operational capability across a range of threat scenarios. This role requires expertise in MATLAB and Python and the ability to develop analytical tools, interpret complex simulation results, and communicate technical findings to engineering team, program leadership, and government stakeholders.

• →Perform performance analyses of Ground-based Missile Defense (GMD) system capabilities using modeling and simulation tools.
• →Develop and execute analytical methodologies to evaluate system effectiveness, interceptor performance, engagement outcomes, and mission success.
• →Design, develop, and maintain analytical tools using MATLAB and Python.
• →Conduct statistical analyses, sensitivity studies, Monte Carlo simulations, and trade-space assessments to support engineering and program decisions.
• →Analyze large datasets generated from missile defense simulations to identify trends, assess system performance, and recommend improvements.
• →Develop technical reports, presentations, and data visualizations that clearly communicate analytical results to government and contractor leadership.
• →Collaborate with systems engineers, modeling and simulation teams, software developers, and subject matter experts to define analysis approaches and performance metrics.
• →Support design reviews, technical interchange meetings, and customer briefings.
• →Maintain analytical documentation and ensure consistency of modeling assumptions and methodologies.

• Master’s Degree in STEM with + 12 years relevant experience.
• Demonstrated experience supporting MDA GMD Programs.
