Job description
About Roguebeam
Roguebeam is an early-stage company building advanced phased-array systems for radar and communications. We design complete systems in-house: RFICs, antenna elements, RF front ends, digital control, and signal processing. Our products serve defense, satellite, and radar applications, and our small team has shipped complex hardware at scale.
The Role
We are hiring a Senior Radar Engineer to own the signal processing chain of our Ku-band phased-array radar, from waveform to track. You will develop the algorithms that turn raw array data into reliable detections and tracks of small, low-RCS targets such as drones, and carry them from models in MATLAB or Python to real-time implementation on FPGA and SoC hardware with our DSP, FPGA, and RF engineers.
This is a hands-on role. You will write the models, run the lab and field tests, and work directly with the data.
Responsibilities
Define radar waveforms and operating modes (FMCW, pulse-Doppler, LFM and phase-coded) and trade range resolution, unambiguous velocity, duty cycle, and search timeline against system requirements
Develop the end-to-end processing chain: pulse compression, range-Doppler processing, digital beamforming, clutter suppression, CFAR detection, and angle estimation
Build detection and tracking algorithms for small, slow, low-flying targets in clutter, including track initiation, data association, and state estimation
Develop target discrimination methods, such as micro-Doppler feature extraction, to separate drones from birds and ground clutter
Build and maintain radar performance models (range equation, SNR and detection probability, clutter and multipath, array pattern and scan loss) that drive architecture decisions for the array, RFIC, and digital back end
Partner with DSP and FPGA engineers to partition algorithms across FPGA, SoC, and host; define fixed-point and latency budgets; and verify implementations bit-true against reference models
Plan and run lab and field tests: collect and analyze data, characterize system performance, and close the loop between model and measurement
Work with the RF and antenna teams on array calibration and beam-steering strategy
Required Qualifications
BS in Electrical Engineering, Physics, or a related field
5+ years developing radar signal processing algorithms for fielded or prototype radar systems
Strong DSP fundamentals: sampling and multirate processing, filter design, spectral estimation, detection and estimation theory, and statistical signal processing
Hands-on experience with pulse-Doppler and/or FMCW processing: pulse compression, range-Doppler maps, MTI/MTD clutter filtering, and CFAR
Array signal processing experience: digital or hybrid beamforming, angle-of-arrival estimation, and monopulse
Fluency in MATLAB and/or Python for algorithm development and data analysis
Experience taking algorithms to hardware, including fixed-point conversion, real-time constraints, and verification alongside FPGA or embedded engineers
Experience collecting and analyzing data from real radar hardware in the lab and field
Preferred Qualifications
MS or PhD in Electrical Engineering or a related field
Counter-UAS, short-range air surveillance, or small-target detection experience
Adaptive beamforming, STAP, or high-resolution direction finding (MUSIC, ESPRIT)
Experience with MIMO, multistatic, or networked radar architectures and advanced waveform design
Multi-target tracking (IMM, JPDA, MHT) and sensor fusion across networked radars
Micro-Doppler analysis or machine-learning-based target classification
C/C++ for real-time processing; familiarity with HDL, HLS, or AMD RFSoC platforms
Ku- or Ka-band phased-array experience, including array calibration
Active U.S. security clearance
Why Roguebeam
This is a rare ground-floor opportunity. Joining a startup at this stage means your work has a direct, visible effect on whether the company succeeds—and a corresponding upside as we grow. Because we build the entire system in-house, you’ll see your software running on real phased arrays and deployed in working systems, not handed off and forgotten. You’ll have real ownership and a seat at the table on technical direction.
Export Control
This position requires access to technology and technical data subject to U.S. export control regulations, including the International Traffic in Arms Regulations (ITAR). Applicants must be U.S. persons as defined in 22 CFR 120.62 (U.S. citizens, U.S. lawful permanent residents, or protected individuals under 8 U.S.C. 1324b(a)(3)).
