You will have the opportunity to work on mission-critical projects that directly impact national security, collaborate with multidisciplinary teams, and advance your technical expertise in a supportive and innovative environment.

Requirements

Must be a U.S. Citizen and be able to obtain a Top Secret/Sensitive Compartmented Information (TS/SCI) security clearance.
Bachelor’s degree in a STEM field and 5+ years of relevant experience; OR Master’s degree in a STEM field and 3+ years of relevant experience; OR PhD in a STEM field and 1 year of relevant experience.
Experience developing, implementing, and executing six-degree-of-freedom (6DOF) and three-degree-of-freedom (3DOF) simulations using MATLAB/Simulink, Python, and C++ to model threat system components, engagement scenarios, and sensor behavior.
Demonstrated expertise in EO/IR sensor and seeker modeling, as well as knowledge of missile or space vehicle dynamics, guidance, navigation, and control, and associated numerical methods and state estimation techniques.
Experience integrating sensor models with EO/IR scene generation platforms.
Proven ability to clearly communicate complex technical analyses and assumptions to government customers and non-technical stakeholders.
Strong programming skills in C++, Python, and/or MATLAB.

Nice To Haves

Active TS/SCI Clearance with CI Polygraph.
Hands-on experience leading software development efforts for EO/IR sensor/seeker models supporting BMD and ASAT system assessments or acquisition activities.
Background working with intelligence organizations, including direct support to acquisition programs, requirements development, and technical review processes.
Experience serving as a technical lead or project manager, including planning tasks, tracking financials, managing schedules, and ensuring the quality and timeliness of M&S deliverables.
Experience with artificial intelligence/machine learning (AI/ML) techniques and their application in EO/IR sensor/seeker systems.
Familiarity with missile defense architectures, threat characterization methodologies, and verification/validation of high-fidelity sensor and seeker models.
Proficiency with software engineering best practices (configuration management, Git, code review, automated testing) and experience working in Linux, high-performance computing (HPC), or cloud-based simulation environments.

Responsibilities

Leading the design, development, and integration of high-fidelity EO/IR sensor and seeker models for BMD and ASAT threat systems, supporting intelligence and acquisition stakeholders.
Designing scenarios, conducting trade studies, and performing sensitivity analyses to assess EO/IR seeker performance, threat capabilities, and system-level impacts for missile defense missions.
Documenting modeling assumptions, algorithms, and results, and preparing technical reports, validation documents, and briefings to support MSIC products and acquisition decision-making.
Collaborating with multi-disciplinary engineering teams and customers, providing technical leadership, status updates, and timely responses to evolving analysis and modeling & simulation (M&S) requirements.
Participating in professional development opportunities and contributing to a culture of innovation and continuous learning.
Working in a flexible environment with options for onsite, hybrid, or remote work (subject to project requirements).
Engaging with a diverse and inclusive workforce, and benefiting from Parsons’ commitment to employee well-being, work-life balance, and career advancement.
