Sr. Navigation Engineer

Engineering     San Mateo, CA     Full-time

Xona Space Systems a is start-up focused on building satellite navigation infrastructure for the age of autonomy. Global Navigation Satellite Systems (GNSS) like GPS brought navigation to the masses. Looking forward, cyber-physical systems including self-driving cars, aerial mobility, and mobile robotics are pushing the limits of what GNSS can provide. In these applications, GNSS faces challenges with precision, interference, and security. Xona’s commercial low-Earth orbit navigation service is being designed to meet these challenges by providing high security GNSS with more than an order of magnitude better accuracy and availability than current state of the art.

Our success is dependent upon building an agile team that thrives on doing more with less. We are curious, passionate, innovative, and thrive in a collaborative environment.

Xona is looking for a Sr. Navigation Engineer to join our team to support algorithm development for our space, ground, and operational systems.  Our navigation team tackles problems in orbit determination, clock estimation, user positioning, atmospheric modelling, and integrity for safety critical applications.

What You’ll Do

  • Design and development of state-of-the-art navigation algorithms for constellation-wide orbit determination, clock synchronization, atmospheric modelling, and end-user positioning

  • Large-scale simulation development for algorithm prototyping and validation

  • Design of experiment to validate the algorithms in ground and on-orbit testing

  • Support larger navigation system architectural design

  • Support development and testing on bench-top prototypes and flight hardware


What You Have

  • Master’s or PhD in Aerospace Engineering, Electrical Engineering, Mechanical Engineering, Geomatics Engineering, Mechatronics, or equivalent

  • 3+ years experience working on navigation, localization, or estimation algorithm development for automotive, industrial, or aerospace applications

  • Expertise in Kalman Filtering and other estimation techniques

  • Experience in software development and algorithm prototyping using MATLAB


Preferred Skills and Experience

  • Production algorithm development experience

  • Experience with statistical signal processing

  • Experience with satellite systems, particularly Guidance, Navigation, and Control

  • Experience with GPS, GNSS

  • Experience with orbital mechanics / orbit determination

  • Familiarity with atmospheric sciences and modelling

  • Familiarity with satellite communication systems
