Job Description
Do you want to be part of oneNav’s disruptive next-generation GNSS products that are resilient in the field? We are seeking a hands-on technical deep GNSS Signal Processing Systems Engineer for our Advanced Products & Systems team to realize oneNav’s goals. You will design anti-jamming and anti-spoofing algorithms, build working solutions, analyze KPIs, and collaborate across hardware and software teams to bring prototypes to production. Success in this role requires strong technical depth, independent thinking, and effective collaboration in a fast-paced environment.

- Design and implement beamforming and spatial-filtering algorithms (e.g., MVDR, LCMV, adaptive nulling) to suppress jammers.
- Apply statistical detection and estimation theory (Bayesian estimation, hypothesis testing) to jammer/spoofer detection, classification, and mitigation.
- Develop and validate countermeasures against commonly encountered interference types, including CW, chirp, and other structured/unstructured jamming and spoofing signals.
- Contribute to system-level architecture for next-generation resilient PNT products, evaluating trade-offs across HW, FW, and SW in close collaboration with RF and ASIC teams for low SWaP-C implementation.
- Build prototypes and drive them to measurable KPIs such as J/S performance across In-Band/Out-of-Band, Acquisition, Tracking, and Re-acquisition.
- Translate algorithm designs into production-quality embedded code alongside the software team, adhering to established coding standards.
- Contribute to advanced initiatives applying machine learning to jammer/spoofer classification and mitigation alongside classical estimation approaches.
