Flight Navigation Software Engineer

Engineering     San Mateo, CA     Full-time

Xona Space Systems is a 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 Flight Navigation Software Engineer to join our team to support navigation algorithm implementation on flight hardware. This position intends to bring prototype algorithms and schema developed by our research staff and subject matter experts into production where you will be responsible for specifying, implementing, and verifying embedded software components for our navigation payload and spacecraft.

What You’ll Do

  • Collaborate with multidisciplinary teams to create real-time embedded software to support navigation and diagnostics of commercial navigation spacecraft

  • Define software architecture and standards needed to achieve flight readiness for safety-critical applications

  • Work with subject matter experts to implement and enhance algorithms, define software / hardware tests, experiments, and metrics for success

  • Write code to implement designs in C/C++

  • Support system integration, debugging, and hardware in the loop testing with flight hardware in a lab environment


What You Have

  • Master’s in Electrical Engineering, Computer Engineering, Aerospace Engineering, Mechanical Engineering, or equivalent

  • 3+ years of professional software development experience

  • Experience with embedded software design and implementation for automotive, industrial, or aerospace/military applications with proven success in a fast-paced, cross-functional engineering team environment

  • Experience in software development and algorithm prototyping using MATLAB
