Job DescriptionSAIC is hiring a Senior Principal Radar Signals Engineer to join a mission-driven analysis team in Chantilly, VA supporting multiple satellite programs at the forefront of national innovation. This team is advancing novel satellite missions that directly support national priorities, operating within a highly engaged Government environment with frequent access to senior Government decision-makers. The engineer will lead modeling, simulation, and analysis of satellite-tracking radar systems for satellites in a wide range of Earth orbits, collaborating with experts in propulsion, optics, AI/ML, cloud, GPUs, and astrodynamics.
Responsibilities include, but are not limited to:- Design and analyze satellite-tracking radar signals, waveforms, and signal processing algorithms to support detection, acquisition, tracking, and characterization of space objects.
- Perform antenna design and analysis, including performance modeling and trade studies, to optimize radar system effectiveness against satellite targets in LEO, MEO, GEO, and other orbits.
- Develop and apply modeling and simulation tools to evaluate end-to-end radar performance and mission concepts, leveraging Python, C++, MATLAB, or similar tools and high-performance computing resources.
- Conduct independent trade studies and technical assessments, and review/validate algorithms, models, and analysis results from internal and external teams.
- Collaborate with a multi-disciplinary team (astrodynamics, optical sensing, AI/ML, cloud/HPC) to simulate mission operations concepts at scale and provide integrated, actionable insights to customers.
- Develop and present clear, technically rigorous briefings and recommendations to senior Government customers and internal stakeholders.
- (Optional) Perform radar return modeling using 3D satellite models to support characterization and concept-of-operations analyses.
Qualifications- Bachelor's degree in Electrical Engineering, Applied Mathematics, Physics, or a related technical field and 14+ years of relevant experience;
- OR Master's degree and 12+ years of relevant experience;
- OR PhD (or JD with directly relevant technical experience) and 9+ years of relevant experience.
- Demonstrated experience with target-tracking radar signals, including signal design and digital signal processing for detection, tracking, and characterization.
- Strong foundation in electrical engineering, advanced mathematics, and digital signal processing (DSP).
- Proficiency with Python, C++, MATLAB, or similar languages for modeling, simulation, and analysis of radar or RF systems.
- Proven experience conducting independent technical analyses, trade studies, and assessments, and documenting results in technical reports or briefings.
- Ability to work effectively in a multi-disciplinary team environment, and to communicate complex technical topics clearly to both technical and non-technical stakeholders.
Clearance Requirements:
- Active TS/SCI clearance with the ability to obtain and maintain a Polygraph.
- Must be willing and able to work onsite in Chantilly, VA in a classified environment.
Preferred Qualifications:
- Experience with space domain awareness (SDA), space surveillance, or satellite-tracking radar systems.
- Background in antenna design, phased arrays, or RF front-end architectures for radar systems.
- Experience modeling radar performance against satellites in varied orbital regimes, including consideration of clutter, interference, and environmental effects.
- Familiarity with high-performance computing (HPC) environments, GPU-based processing, or cloud-based modeling and simulation workflows.
- Experience working directly with senior Government customers, including preparing and delivering technical presentations and recommendations.
- Prior experience in a lead, principal, or subject-matter-expert role, including mentoring junior engineers or analysts.
Physical Requirements:
- Work is primarily performed in an office, laboratory, or classified facility environment.
- Ability to work at a computer workstation for extended periods, including frequent use of standard office and IT equipment.
- Occasional walking, standing, and movement between offices, conference rooms, and secure areas.
- Ability to participate in on-site meetings and briefings, which may require extended periods of sitting and focus
