Requirements
- 6+ years professional experience in DSP engineering, SIGINT/technical signal analysis, RF exploitation, or closely related roles.
- Bachelor’s degree or higher in a STEM discipline (e.g., Electrical Engineering, Computer Engineering, Computer Science, Physics, Applied Mathematics).
- Active TOP SECRET/SCI clearance and current polygraph (must be in-scope per customer requirements).
- Demonstrated experience implementing DSP algorithms in software (C/C++ and/or Python).
- Demonstrated CUDA development experience including kernel implementation and performance optimization.
- Strong fundamentals in signals and systems (sampling, filtering, FFT/spectral analysis, detection/estimation).
- Experience working with complex IQ data and RF/signal processing toolchains.
- Ability to translate operational/analytic needs into technical requirements and reliable implementations.
Nice To Haves
- Master’s degree or PhD in a relevant STEM field.
- Experience with real-time SDR ecosystems (USRP/Ettus, SoapySDR, GNU Radio) and/or RF front-end integration.
- Experience with cuFFT and GPU-centric optimization patterns (streams, pinned memory, kernel fusion, overlap compute/I/O).
- Experience with multichannel processing (PFB/channelizers, array processing, DF/beamforming concepts).
- Familiarity with basic ML-based signal classification workflows and dataset curation.
- Linux performance tuning; containerized deployments; reproducible builds.
- Experience mentoring engineers and driving technical architecture decisions.
Responsibilities
- Develop and implement DSP algorithms (e.g., channelization/PFB, detection, synchronization, estimation, demodulation/decoding, feature extraction).
- Design and validate processing chains under real-world RF impairments (CFO/phase noise, multipath, interference, IQ imbalance).
- Establish quantitative validation (Pd/Pfa, BER/EVM where applicable) using test vectors and field-captured IQ.
- Perform technical signal analysis to characterize signals of interest and derive actionable observables.
- Develop signal characterization artifacts (parameters, fingerprints, modulation traits, timing/structure) and automate repeatable workflows.
- Collaborate with operators/analysts to refine requirements and iterate quickly against mission needs.
- Implement and optimize GPU-accelerated components (FFT pipelines, filter banks, correlation/matched filtering, detection/thresholding, beamforming primitives where applicable).
- Profile and tune performance using NVIDIA tooling (e.g., Nsight) focusing on memory behavior, occupancy, launch overhead, and concurrency.
- Integrate CUDA into production pipelines (C/C++ and/or Python bindings), including multi-stream and multi-GPU approaches when required.
- Build throughput/latency benchmarks and performance regression tests.
- Deliver maintainable, modular code with unit/integration tests and CI-friendly builds.
- Integrate with streaming and batch processing systems (SDR front ends, file processing, message buses).
- Document algorithms, interfaces, data formats, and operational constraints suitable for cleared environments.
