Principal Radar Signals Engineer

SAIC is hiring a Radar Signals Engineer to join a mission-driven, multi-disciplinary analysis team in Chantilly, VA, supporting multiple satellite programs at the forefront of national innovation. 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.

Responsibilities include, but are not limited to:

- Design and analyze satellite-tracking radar waveforms and signal processing algorithms for detection, acquisition, tracking, and characterization of space targets.
- Perform radar and antenna performance analyses, including link budgets and tracking performance across LEO, MEO, GEO, and other orbital regimes.
- Develop and execute modeling and simulation of radar-to-satellite engagement scenarios, including optional radar return modeling using 3D satellite models.
- Use programming languages such as Python, C++, MATLAB, or similar tools to implement, validate, and enhance models, simulations, and data-processing pipelines.
- Conduct 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.
- Document findings and develop actionable technical briefings, with opportunities to present results to senior Government stakeholders.
