Senior GNSS/INS Navigation Engineer

About the role

u-blox is looking for a Senior GNSS/INS Navigation Engineer to join a high-performing R&D team. The engineer combines deep expertise in GNSS positioning, inertial navigation, estimation theory and multi-sensor fusion with strong software skills, turning advanced algorithms into robust, production-ready solutions. The role spans the full algorithm development lifecycle, from concept and prototyping through implementation, verification, optimization and product release.

Key responsibilities

• Design, develop and enhance core GNSS, navigation and multi-sensor fusion algorithms for embedded positioning products.
• Work across the full development lifecycle, from requirements and feature definition to implementation, validation and release.
• Implement algorithm concepts in production-quality software using C/C++.
• Analyse navigation performance and investigate challenging real-world operating scenarios.
• Develop and maintain automated test solutions in Python to ensure product quality and efficient verification.
• Create and maintain technical documentation for functional blocks, features and development activities.
• Investigate software defects and customer-reported issues, developing fixes and workarounds where needed.
• Collaborate on work planning and technical discussions, and contribute to technical roadmaps, innovation activities and patent generation.

Required profile

• Master's or PhD in Electrical Engineering, Computer Science, Robotics, Aerospace Engineering, Physics, Mathematics or a related field.
• 7+ years of experience developing GNSS/INS navigation solutions, multi-sensor fusion or related positioning technologies.
• Strong understanding of GNSS positioning fundamentals, including measurement processing, estimation techniques, statistical methods and performance analysis.
• Fluent in English; excellent communication and teamwork abilities.

Required skills

• C/C++ and Python.
• Software engineering best practices, version control, CI/CD and code review.
• Debugging, data analysis and validation and testing in simulated and real-world environments (e.g. SIL/HIL).
• Familiarity with agile software development.

Nice to have: experience with automotive, autonomous systems, robotics, UAVs or precision navigation; knowledge of PPP, RTK, carrier-phase processing and ambiguity resolution; embedded systems and real-time software; machine learning for navigation; patents or technical publications in navigation.

What we offer

• A key leadership role in a global, technology-driven company with a high degree of ownership over product quality, cost and time-to-market.
• Collaboration with leading semiconductor manufacturing partners worldwide.
• An open, supportive and technically strong engineering culture.
• Flexible working, with work from home offered for a number of days a week.
• Above-average social benefits.
