Sr. Navigation Estimation Engineer

Sr. Staff Navigation Estimation Engineer

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.

• 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.

• 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.

• 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.
