About Spire

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.

The role

As an SDR payload software engineer, you will be part of a team developing payloads for several different applications, including ADS-B and AIS receivers to track airborne and maritime traffic. You will interface with other teams at Spire such as the algorithm design, hardware, manufacturing and operations teams that design, build, test and operate the SDR payloads. Our satellite constellation is continuously growing and also improved through on-orbit software and FPGA updates. If you have the drive to write stable, high-performance software that will have a global impact, we'd love to hear from you.

  • Continuously improving the payload software in terms of performance and functionality
  • Ensuring interoperability between the payload and the platform and data handling subsystems
  • Be hands-on in laboratory and manufacturing environments during bring-up, integration, qualification, testing and debugging of SDR payloads
  • Conducting peer-reviews of code written by other team members

Basic qualifications / Experience

  • Experience in design, implementing and testing of application software in modern C++
  • Experience in developing high-performance and memory-efficient C or C++ code for embedded systems with real-time constraints
  • Bachelor’s degree in Computer Science, a technical field relevant to software engineering, or equivalent real-world experience
  • A detail-oriented personality; careful, methodical, and persistent in tracking down problems

 Preferred Qualifications / Experience

  • Experience in adapting and configuring Linux on embedded systems using Yocto or similar
  • Experience in reading schematics and datasheets, and interfacing with HW designers and FPGA developers
