- Experience with GNSS receiver data, signal correlation techniques, and understanding of GNSS ICDs (e.g., GPS, Galileo, BeiDou)
- Hands-on experience with SDRs and lab instruments such as spectrum analyzers, oscilloscopes, GNSS receivers, and network analyzers
- Programming or scripting skills (Python, MATLAB, or similar) are a strong asset
- GNSS background is a plus, but not mandatory
- Strong troubleshooting skills and ability to work collaboratively across teams
- Excellent communication and technical documentation skills in French and English
