GNSS Applications & Earth Information Sales Engineer at Spire Global
Glasgow, GB


Spire Global is a space-to-cloud analytics company that owns and operates the largest multi-purpose constellation of satellites. Its proprietary data and algorithms provide the most advanced maritime, aviation, and weather tracking in the world. In addition to its constellation, Spire’s data infrastructure includes a global ground station network and 24/7 operations that provide real-time global coverage of every point on Earth.


Spire’s Earth Observations (EO) Team is growing a portfolio of EO products ranging from atmospheric profiles to space weather (SpWx) monitoring. The SpWx group of the EO Team is a small but agile team tasked with using large quantities of satellite data assimilated into an ionosphere model to create real-time corrections to improve the performance of GNSS location-based services and other applications. Positioning errors from ionospheric effects on GNSS signals remain one of the last hurdles in improving positioning accuracy for legacy single frequency users and for real-time GNSS precise point positioning (PPP). Furthermore, ionospheric errors can increase the time to first fix in real-time kinematic (RTK) systems and ionospheric scintillation can reduce the accuracy of all GNSS systems.

As a GNSS Applications and Earth Observations Sales Engineer, you will be a primary technical contact to customers on behalf of Spire's products for GNSS applications. Successful candidates will have a good balance of experience with GNSS systems engineering, with a holistic view of the space, ground, and user segments and an understanding of how external corrections may be used to improve GNSS operations. You will help transform the outputs of our ionospheric data assimilation model into useful near real-time corrections for GNSS services, leading to greater confidence in applications that require high accuracy and resilience, such as autonomous vehicle navigation. You will also contribute support to general EO sales efforts that include government, commercial, and research customers.


Evaluate customer needs for GNSS services, specifically for applications requiring real-time corrections of ionosphere-induced positioning errors (e.g., autonomous vehicle navigation)

Work with the ionosphere modelling and data assimilation teams on defining system requirements based on customer needs

Coordinate real-time delivery of the GNSS corrections produced by the ionospheric data assimilation model to customers

Interact with customers and plan pilot projects that will transform into long-term contracts for real-time GNSS corrections services

Interface with general EO customers to determine how Spire products could meet their needs and relay this information to the EO engineering and product groups
