Position Overview: 
The Senior Navigation Engineer architects, develops and implements positioning algorithms for collision avoidance, assisted driving and autonomous vehicle applications.  These navigation algorithms blend inputs from multiple sources (GNSS, inertial sensors, vehicle dynamics, precision maps and vision system inputs) to robustly locate a vehicle to sub-meter levels of accuracy.   

Working in a small team environment and collaborating with several other divisions, the navigation engineer enjoys broad exposure to the complete product life cycle, from concept creation through implementation, qualification and production phases.  The Division thrives on close working relationships with both the automotive Tier 1 suppliers and their OEM customers and this position will benefit from periodic customer interaction. 

Ideal candidates have many tools in their belt, take initiative and thrive in a fast-paced, small-team environment.  This is not a pure research role.  The navigation engineer will see their work reach production and generate revenue.

Primary Responsibilities:
The navigation specialist performs a broad range of duties, including:
  • Analyzing and characterizing sensor and GNSS measurements
  • Designing sensor calibration strategies and models
  • Developing navigation Kalman filters fusing measurements from numerous sources
  • Establishing navigation performance metrics and evaluation tools
  • Defining test methodologies for exercising navigation corner cases
  • Automating analysis of navigation performance against a truth reference system
  • Implementing models and filters in software suitable for embedded systems
  • Additional duties as required for program success.

Minimum Qualifications: 
Successful navigation specialists come from a variety of backgrounds and a single “formula” for success does not exist.  Some desired characteristics include:
  • A Masters or PhD degree in a related engineering discipline, an applied science such as Physics, or in applied mathematics.  An undergraduate degree with years of relevant experience is also acceptable.
  • 10 years of commercial experience developing navigation algorithms or a mix of equivalent academic and commercial experience.
  • Strong analytical and math skills and comfort with mathematical modeling tools such as Matlab.
  • Experience with GNSS or GPS navigation in aerospace, defense, aeronautics, marine or other inertial navigation applications.
  • Familiarity with automotive grade inertial sensors, such as accelerometers, gyroscopes, magnetometers and altimeters.
  • Experience implementing algorithms and models in software using C or C++ programming languages.
  • A background in developing positioning technology for automotive applications would also be beneficial.

Do not allow the list above deter you from applying for the navigation specialist if you believe that  the combination of your experience, skill set and drive to learn and grow qualifies you for success in this role.
