We are seeking a Staff Navigation Estimation Engineer to develop positioning and estimation software for ADAS/Autonomous Driving. This role focuses on GNSS/INS estimation, raw measurement processing, embedded software implementation, and safety-compliant development in an ISO 26262 environment.
You Will
- Design, develop, and optimize navigation estimation software for embedded automotive platforms.
- Implement positioning algorithms using GNSS, IMU, wheel-speed, and vehicle-motion inputs.
- Develop GNSS measurement processing for observables such as pseudorange, carrier phase, Doppler, and measurement quality indicators.
- Build robust estimation logic including measurement validation, residual monitoring, outlier rejection, and fault detection.
- Develop safety-related software aligned with ASIL-B goals and ISO 26262 software development practices.
- Support simulation, replay, regression testing, and data analysis using vehicle logs and estimator outputs.
- Collaborate with systems, safety, platform, validation, and embedded software teams to deliver production-ready positioning software.
You Bring
- Strong C++ software development experience for real-time, embedded, or high-reliability systems.
- Solid understanding of GNSS measurement models, estimation theory, sensor fusion, and navigation fundamentals.
- Hands-on experience with EKF/UKF, least squares, factor graphs, RTK/PPP, INS integration, or GNSS/INS localization.
- Experience developing production software with attention to reliability, latency, determinism, diagnostics, and testability.
- Experience working in an ISO 26262 environment, preferably with ASIL-B software requirements and verification artifacts.
- Strong debugging skills using logs, simulation results, raw sensor data, estimator states, residuals, and covariance outputs.
- BS/MS/Ph.D. in Computer Science, Electrical Engineering, Robotics, Aerospace Engineering, Geomatics, or a related field; ideally 10+ years of relevant experience.
Nice to Have
- Experience with multi-constellation/multi-frequency GNSS, correction services, ambiguity-resolution support, or GNSS receiver integration.
- Experience with automotive software practices such as ASPICE, MISRA C++, AUTOSAR, SIL/HIL testing, or fault injection.
- Python/MATLAB experience for prototyping, log analysis, visualization, and automated validation.
