Job description

You are a collaborative Senior GNSS/INS Navigation Engineer who enjoys solving complex positioning and navigation challenges as part of a high-performing R&D team. You combine deep technical expertise in GNSS positioning, inertial navigation, estimation theory, and multi-sensor fusion algorithms with strong software engineering skills, enabling you to transform advanced algorithms into robust, production-ready solutions.

You work effectively across disciplines, collaborating with system engineers, software developers, verification engineers, and product teams to deliver world-class positioning performance. You communicate complex technical concepts clearly, contribute actively to technical discussions, and provide guidance to less experienced engineers.

Equally comfortable researching new concepts and delivering commercial products, you take ownership of the complete algorithm development lifecycle, from concept and prototyping through implementation, verification, optimization, and product release. You are driven by data, embrace rigorous testing and validation, and continuously seek opportunities to improve accuracy, robustness, and efficiency.

You thrive in a technically demanding environment, quickly identify key challenges in complex systems, and make sound engineering decisions based on both theory and practical constraints.

With a passion for innovation and excellence, you help strengthen u-blox's leadership in GNSS, sensor fusion, and positioning technologies.

Your Responsibilities:

• Design, develop, and enhance core GNSS, navigation, and multi-sensor fusion algorithms for embedded positioning products
• Contribute 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 using 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.
• Contribute to technical roadmaps, innovation activities and patent generation.

Your Skills and Experience:

• Master's or PhD degree 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.
• Strong software development skills in C/C++ and Python.
• Proficiency with software engineering best practices, version control, CI/CD, and code review processes.
• Strong analytical and problem-solving skills, including software debugging, data analysis, validation and testing in simulated and real-world environments (e.g., SIL/HIL)
• Familiarity with agile software development practices.
• Excellent communication and teamwork abilities. Fluent in English.

Nice to have:

• Experience developing algorithms for automotive, autonomous systems, robotics, UAVs, or precision navigation applications.
• Knowledge of PPP, RTK, carrier-phase processing, and ambiguity resolution.
• Experience with embedded systems and real-time software.
• Familiarity with machine learning techniques applied to navigation and positioning.
• Patent portfolio or record of technical publications in navigation-related fields.
• What we offer:A key leadership role in a global, technology-driven company.
• High degree of ownership and impact on product quality, cost, and time-to-market.
• Collaboration with leading semiconductor manufacturing partners worldwide.
• An open, supportive, and technically strong engineering culture.

We offer a challenging position within an international work environment. You will be working with a young team in exciting technology. Our employment conditions are attractive with above average social benefits. In addition, we support flexible working, with work from home offered for a number of days a week.
