About The Role

We're hiring a Product DSP Engineer to move RF signal processing from working in the lab to working in the field. You'll own the production signal chain: making it deterministic, real-time, and reliable in contested RF environments. This role will focus on implementing and refining algorithms to run consistently on the target hardware within the latency, power, and thermal budgets, with the adequate test coverage and validation. You'll have real ownership of your work, the problems are challenging, and your teammates hold themselves to a high standard.

Responsibilities

Production-izing detection, classification, tracking, and direction-finding/geolocation algorithms for target hardware (NVIDIA Jetson, FPGA, SDR) within fixed compute, memory, latency, and power budgets
Building regression and characterization test suites that validate signal-chain performance against real and synthetic data
Accounting for the behavior and inconsistencies of the target RF hardware in your algorithm design
Making algorithms robust against real-world conditions: interference, multipath, dense emitter environments, dropouts, calibration drift, and temperature
Doing the fixed-point/quantization, profiling, and optimization work needed to hit real-time on embedded targets
Defining and tracking performance metrics (Pd/Pfa, sensitivity, DF accuracy, latency) as product acceptance criteria
Supporting field test, reproducing field issues in the lab, and owning root cause through fix

Qualifications

BS/MS in mathematics, physics, electrical engineering, computer science, or related technical field
Broad understanding of RF hardware effects, and intricacies of coherent and non-coherent systems
Solid RF signal processing fundamentals: detection, estimation, the full transmit/receive chain
Demonstrated track record shipping DSP into a product or fielded system
Proficiency in MATLAB and/or Python for analysis, and C/C++ for production code
Comfort working under embedded/real-time constraints, with profiling and optimization
Must be eligible to obtain and maintain a U.S. TS clearance; U.S. person required

Nice-to-Have

FMCW/automotive radar chains, MIMO arrays and subspace AoA estimation, or SAR production chains (backprojection, polar formatting, range migration)
Fixed-point DSP implementation; FPGA or GPU/CUDA acceleration
Test automation and hardware-in-the-loop (HIL) for signal processing
Experience fielding the same core technology in seemingly independent con-ops
