About the role
Key responsibilities & impact- Design and implement the end-to-end DSP pipeline from raw IQ sample ingestion through spectral analysis, channelization, filtering, and feature extraction.
- Implement and validate algorithms multi-sensor RF geolocation algorithms.
- Build and maintain signal detection, framing, and classification primitives that serve as inputs to downstream ML pipelines.
- Write optimized signal processing code in C/C++ targeting embedded processors and FPGA soft-core environments on edge hardware.
- Experience porting DSP workloads to server-class or cloud compute environments.
- Profile and optimize algorithms for latency, throughput, and power within tight edge compute budgets.
- Define and implement data pipeline interfaces between the edge layer and cloud/server-side processing, including IQ data formatting, metadata schemas, and transport protocols.
- Contribute to system-level design reviews, interface control documents, and technical roadmap planning.
Requirements
What you’ll need- Bachelor's or Master's degree in Electrical Engineering, Signal Processing, Applied Mathematics, or a closely related field.
