Radar Engineer

The role

You will own the radar sensing layer of a counter-sUAS kill chain. This involves integrating and tuning radars from multiple vendors to feed detections and tracks into the company platform.

What you will do

• Run bench and range characterization of radars to verify performance and establish baselines.
• Integrate multiple radar models into the counter-drone platform.
• Design, build, and maintain software that configures radars and processes detections and tracks.
• Tune radar parameters to maximize detection and minimize false alarms.
• Work with perception and controls teams to fuse radar tracks with acoustic and EO/IR data.
• Build and execute test plans including simulation, hardware-in-the-loop, and live-flight range testing.
• Support radar setup, site surveys, and tuning during customer demonstrations and field deployments.
• Produce and maintain integration documentation, interface control documents, and test reports.

Required qualifications

• 5+ years of hands-on experience as a radar engineer, radar systems engineer, or similar role.
• Experience integrating radars into larger systems and taking integration to fielded use.
• Experience tuning radar configuration and processing parameters in real-world clutter.
• Strong working knowledge of radar principles including radar range equation, RCS, Doppler processing, CFAR, clutter, multipath, and multi-target tracking.
• Proficient in C++ and Python.
• Ability to write production-quality code for radar data ingestion and processing on Linux.
• Ability to diagnose issues across RF hardware, networking (TCP/UDP), timing, and software layers.
• Ability to use lab equipment such as spectrum analyzers and oscilloscopes.
• U.S. citizen.
• Willing to submit a background check.
