Cambridge, ON, Canada
Posted on Friday, October 20, 2023

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.

As a GNC/AOCS Engineer at Spire, you will operate as part of a technical team who maintains responsibility across the full lifecycle of its engineering products. The GNC team interfaces directly with many engineering groups to conduct R&D, design, manufacturing, and operations activities, ultimately ensuring all current and future spacecraft systems satisfy their mission.

Ideal candidates will embrace the commercialisation of nanosatellite systems and adapt to low-cost, fast-paced systems design, development, and implementation methodologies that set Spire apart from our competition. In this fast-paced environment, the design to launch cycle is measured in weeks and months, not years!

Responsibilities of your role:

  • Technical ownership of current and future spacecraft attitude and orbit control software and hardware
  • Design, model, analyze, integrate and operate attitude determination/estimation systems for small spacecraft
  • Develop and utilize spacecraft dynamics and control simulations, including 'hardware-in-the-loop'
  • Design, evaluate, select, qualify and implement flight sensors, including magnetometers, sun sensors, inertial measurement devices, infrared sensors, and/or star trackers
  • Design, evaluate, select, qualify and implement flight actuators, including magnetic torque elements, reaction wheels, and propulsion systems
  • Be hands-on in laboratory and manufacturing environments during testing, integration, and qualification of flight systems
  • Provide support and analysis for on-orbit operations of spacecraft attitude determination and control systems
  • Work with external contractors, manufacturers, and internal manufacturing staff to improve reliability, yield, performance, and cost of flight systems

Qualifications / Experience:

  • Extensive experience with a solid foundation in spacecraft attitude dynamics and control algorithms, with emphasis on practical application of knowledge.
  • Have experience designing and/or implementing Kalman filters for attitude estimation
  • Experience with flight sensors for spacecraft attitude determination/estimation
  • Experience developing software using C/Python
  • Have experience or familiarity with the Linux development environment
  • Have experience working with external engineering contractors

Preferred Qualifications:

  • Experience writing flight software
  • Experience with C or C++ development for embedded systems
  • Experience with spacecraft design
  • Experience with spacecraft assembly, integration, and testing
  • Experience with spacecraft operations and maintenance
  • Experience identifying and resolving system anomalies
  • Experience creating and maintaining integration and test campaigns for attitude determination and control systems, including hardware and software

Spire operates a hybrid work model and this position will require you to work a minimum of 3 days per week in our Cambridge, ON office.

Access to US export controlled software and/or technology may be required. #L
