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.

We are looking for an experienced GNC Engineer to join our team in Glasgow. 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'
  • Directly contribute to the on-board software that implements the attitude determination and control algorithms. (C programming)
  • Help maintain our simulator framework and ground side analysis and calibration tools (C and Python programming)
  • 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.

Basic Qualifications / Experience

  • BSc in Engineering, Computer Science, equivalent STEM-related subject, or equivalent work experience.
  • Solid understanding of spacecraft (or other vehicle) dynamics and control algorithms
  • Understanding of estimation techniques (Kalman filter and its extended variants)
  • Experience using sensors and actuators for spacecraft (or other vehicle) navigation and control
  • Proficiency developing software using C

Preferred Qualifications

  • Mastery of C/ C++ software development for embedded systems
  • Solid understanding of the systems-level tradeoffs when designing attitude control systems for different missions
  • Experience designing and implementing Kalman filters for spacecraft attitude estimation
  • Experience selecting, analyzing, or developing sensors for spacecraft attitude estimation
  • Experience writing spacecraft flight software
  • Experience in Python software development
  • Experience participating in spacecraft systems engineering activities, including mission and spacecraft design across multiple domains
  • Experience in spacecraft operations, including the identification and resolution of spacecraft anomalies
  • Experience creating and maintaining AIT (assembly, integration and test) procedures, software, and systems for spacecraft systems containing hardware and software components
  • Experience working with external engineering contractors or agencies
