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 commercialization 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!

What You’ll Do:

• 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.

Key Skills:

• 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 Skills:

• 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 three days per week in the office.
Access to US export-controlled software and/or technology may be required for this role. If needed, Spire will arrange the necessary licenses—this is not something candidates need to have before applying. #LI-MI1

We are seeking a highly skilled Quality Engineer with a background in electronics to join our growing Quality team. The role will focus on quality assurance of Spire’s electronic systems, ensuring the reliability and compliance, both within spacecraft hardware and ground-based supporting equipment. Alongside your specialism, you will also contribute across the broader quality domains including manufacturing, supplier quality, engineering, and process improvement. 

The Quality Engineer will collaborate closely with managers and team leads, to implement effective quality measures within their respective teams. 

To excel as a Quality Engineer at Spire, the ideal candidate will possess exceptional problem-solving abilities, ensuring that all processes and products consistently meet or exceed established quality standards. 

What You’ll Do as Quality Engineer:  

Electronics Quality (Primary Focus): 

• Develop and implement quality strategies for electronic assemblies & parts, covering internal developments, COTS components, PCBs, and embedded systems across the full product lifecycle.
• Co-ordinate and support engineering design, test, and manufacturing teams in conducting failure analyses, root-cause investigations, and corrective/preventive actions (e.g. RCA, 8D, 5-Why).
• Monitor, evaluate, and report on in-process quality performance.
• Provide quality oversight of electronic manufacturing processes, including soldering, PCB assembly, reflow, conformal coating, and component selection.
• Collaborate with design engineering to drive DFM, DFT, and reliability improvements. 

 Broader Quality Responsibilities: 

• Maintain and improve the organisation’s Quality Management System (ISO 9001, working towards AS9100).
• Support quality planning, audits, document control, and continuous improvement initiatives.
• Chair cross-functional problem-solving activities across functional domains.
• Participate in supplier evaluations, audits, and ongoing performance management.
• Support production quality activities including first article inspections, process capability, and product acceptance (including environmental and reliability testing).
• Contribute to risk management and compliance across internal and external stakeholders. 

 Key Skills: 

• Degree in Electronics Engineering, Electrical Engineering, or a closely related field.
• Solid understanding of IPC standards (e.g. IPC-A-610, J-STD-001) and electronics manufacturing best practices.
• Strong experience in electronics manufacturing, quality engineering, or hardware reliability.
• Demonstrated use of quality management methodologies such as Six Sigma, Lean, or 8D problem solving.
• Ability to interpret technical drawings, schematics, BOMs, and test documentation.
• Experience working in a fast-paced engineering or high-reliability environment (space, aerospace, defence, or similar).
• Excellent communication skills and ability to work collaboratively across disciplines. 

 Preferred Skills: 

• Familiarity with high-reliability engineering or quality assurance standards used in regulated technical industries.
• Familiarity with incoming inspection processes for electronic components.
• Understanding of reliability testing methods (e.g. thermal cycling, vibration, HALT/HASS).
• Experience working with configuration management or document control systems.
• IPC-A-610 Certification.
