Role summaryThe GNSS / Signal Processing Engineer contributes to the design, development, testing, and validation of Global Navigation Satellite System (GNSS) technologies. The role focuses on GNSS algorithm development, multi-GNSS data analysis, simulation support, and system performance evaluation. In addition, the engineer provides technical support to the Product Owner of the Stella GNSS simulator, participates in customer deliveries, and supports GNSS-related projects across theorganization. The position requires strong analytical skills, digital signal process expertise, andclose collaboration with system engineering and customer-facing teams.Key Responsibilities1. GNSS Algorithm Development & Data ProcessingDesign, develop, and optimize GNSS positioning algorithmsImplement models involving satellite geometry, atmospheric delays, multipath, andmeasurement errorsApply advanced stochastic modelling and filtering techniques to improve robustness andaccuracyProcess multi-GNSS datasets (GPS, Galileo, GLONASS, BeiDou) for validation andperformance assessment2. Support to Product Management and Customer DeliveriesAssist the Product Owner in defining simulation product features, validating releases, andsupporting roadmap decisionsContribute to documentation, test plans, and performance reports for simulator releasesProvide technical expertise for the integration of new GNSS models into the simulationenvironmentProvide recommendations in feasibility studies, customer application domains andcommercial offerings.Provide assistance to the product owner in after sales support3. Contribution to GNSS-Integrated Projects and performance evaluationCollaborate with project teams on solutions integrating GNSS with other sensors ortechnologies (e.g., IMU/INS fusion, atmospheric modelling, remote sensing)Support feasibility studies, simulations, and performance evaluations for projectstakeholdersAssess positioning performance in various operational scenarios (urban multipath,dynamic motion, degraded environments)Education & ExperienceMaster in GNSS, Signal Processing, Radionavigation or related field5-10 years experience as GNSS or Signal Processing EngineerFluent un English & FrenchRequired Technical SkillsSolid knowledge of digital signal processing and GNSS domainStrong experience in multi-GNSS analysis, atmospheric modelling (e.g., troposphere), andstochastic modellingProgramming proficiency in MATLAB, programming in C++ and PythonExperience with filtering techniques (Kalman, extended/unscented filters, stochasticmodelling)Familiarity with GNSS tools and geospatial software is a plusAbility to analyze and visualize large datasetsPosition based in WavreAssignment duration: 6 months
