Sunnyvale, CA US
Position Summary: 

NextNav is launching a groundbreaking location service for smartphones, IOT, and other devices – an ability to determine floor level altitude service across the country – a capability that does not exist at scale anywhere today! No longer constrained by legacy “flat earth” technologies, applications and users will be able to determine floor-level altitude, which is essential for navigation, user context, and relevancy and many other applications that are used indoors. NextNav’s is the highest precision Z-Axis solution proven in the marketplace today and a person joining this team will have the ability to define the space.

This position is for a Senior Systems Engineer working on positioning system performance measurement and analysis through the development of field-test platforms, organizing field test campaigns, and real-time and post-processing performance data analysis.

Help make the world 3D!

Responsibilities
• Develop field-test platforms for the measurement and analysis of the performance of various positioning systems, including terrestrial, GNSS, and sensors.
• Organize targeted field testing campaigns to collect the data for detailed navigation (sub)-system performance analysis.
• Identify performance metrics, create data analysis scripts, analyze field data, and determine positioning system performance bottlenecks and identify potential improvements areas.


Desired Skills & Experience
Required:
• MS in EE/ECE/Other Allied fields
