This role focuses on modeling, simulation, and analysis of target-tracking radar systems for satellites across all Earth orbits, directly supporting high-visibility national priorities. You will work in a secure Government environment with frequent access to senior Government decision-makers and daily collaboration with experts in propulsion, radars, optics, AI/ML, cloud computing, GPUs, and more.\nResponsibilities include, but are not limited to:\nDesign and analyze satellite-tracking radar waveforms and signal processing algorithms for detection, acquisition, tracking, and characterization of space targets.\nPerform radar and antenna performance analyses, including link budgets and tracking performance across LEO, MEO, & GEO.\nDevelop and execute modeling and simulation of radar-to-satellite engagement scenarios, including optional radar return modeling using 3D satellite models.\nUse programming languages such as Python, C++, MATLAB, or similar tools to implement, validate, and enhance models, simulations, and data-processing pipelines.\nConduct independent trade studies and technical assessments of radar architectures, algorithms, and system performance, including review and validation of algorithms and results produced by external teams.\nDocument findings and develop actionable technical briefings, with opportunities to present results to senior Government stakeholders.\n Bachelor’s degree in Electrical Engineering, Applied Mathematics, Physics, or a related technical field and 9+ years of relevant experience; OR\n\nMaster’s degree in a related technical field and 7+ years of relevant experience; OR\n\nPhD or JD in a related field and 4+ years of relevant experience.\n\nDemonstrated experience with target-tracking radar signals, including waveform design, detection/tracking algorithms, or target characterization.\n\nStrong foundation in electrical engineering, advanced mathematics, and digital signal processing (DSP).\n\nProficiency with Python, C++, MATLAB, or similar languages for modeling, simulation, and analysis of radar or signal processing problems.\n\nAbility to work effectively in a collaborative, multi-disciplinary team and clearly communicate complex technical concepts in written reports and oral briefings.\n\nClearance Requirements:\nActive TS/SCI clearance is required.\n\nMust have, or be willing and able to successfully complete, a polygraph examination as required by the customer.\n\nMust be willing and able to work on-site in Chantilly, VA, within a secure Government environment.\n\nPreferred Qualifications:\nExperience with space domain awareness (SDA), satellite tracking, or radar systems specifically designed for space targets or long-range surveillance.\n\nBackground in antenna design, RF/microwave engineering, or radar system architecture and performance modeling.\n\nFamiliarity with orbital mechanics/astrodynamics and modeling satellites in LEO/MEO/GEO or other orbital regimes.\n\nExperience leveraging high performance computing (HPC), GPU-accelerated processing, or cloud environments for large-scale modeling and simulation.\n\nPrior experience supporting Government or DoD/IC customers and presenting technical findings to senior stakeholders.\n\nActive TS/SCI with a Polygraph\n\nPhysical Requirements:\nWork is primarily performed in an office or laboratory environment within a secure facility.\n\nMust be able to sit or stand at a computer workstation for extended periods while performing modeling, simulation, and analysis tasks.\n\nOccasional movement between offices, conference rooms, and secure work areas is required.\n\nAbility to lift and carry up to 20 pounds of laptops, documents, or small equipment as needed.\n\n2026.10.1","description_format":"text","description_chars":3870,"description_truncated":false,"requirements":{"experience_years_min":9,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":true,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United
