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. \nIdeal 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!\nWhat You’ll Do:\nTechnical ownership of current and future spacecraft attitude and orbit control software and hardware.\nDesign, model, analyze, integrate and operate attitude determination/estimation systems for small spacecraft.\nDevelop and utilize spacecraft dynamics and control simulations, including 'hardware-in-the-loop'.\nDesign, evaluate, select, qualify and implement flight sensors, including magnetometers, sun sensors, inertial measurement devices, infrared sensors, and/or star trackers.\nDesign, evaluate, select, qualify and implement flight actuators, including magnetic torque elements, reaction wheels, and propulsion systems.\nBe hands-on in laboratory and manufacturing environments during testing, integration, and qualification of flight systems.\nProvide support and analysis for on-orbit operations of spacecraft attitude determination and control systems.\nWork with external contractors, manufacturers, and internal manufacturing staff to improve reliability, yield, performance, and cost of flight systems.\nKey Skills:\nExtensive experience with a solid foundation in spacecraft attitude dynamics and control algorithms, with emphasis on practical application of knowledge.\nHave experience designing and/or implementing Kalman filters for attitude estimation.\nExperience with flight sensors for spacecraft attitude determination/estimation.\nExperience developing software using C/Python.\nHave experience or familiarity with the Linux development environment.\nHave experience working with external engineering contractors.\nPreferred Skills:\nExperience writing flight software.\nExperience with C or C++ development for embedded systems.\nExperience with spacecraft design.\nExperience with spacecraft assembly, integration, and testing.\nExperience with spacecraft operations and maintenance.\nExperience identifying and resolving system anomalies.\nExperience creating and maintaining integration and test campaigns for attitude determination and control systems, including hardware and software.\nSpire operates a hybrid work model, and this position will require you to work a minimum of three days per week in the office.\nAccess to US export-controlled software and/or technology may be requiredfor this role. If needed, Spire will arrange the necessary licenses-this is not something candidates need to have before applying. #LI-MI1\n\nGlobal Perks\nName Your Satellite Program (NYSP)\nLaunch Attendance\nGenerous Time Off Policy\nEducation Assistance Program\nEmployee Assistance Program (EAP)\nEmployee Stock Purchase Program (ESPP)\nFamily Leave\nFitness Reimbursement\nEmployee Referral Program\nHealthy snacks & beverages in every office\nAbout Spire\nWe improve life on Earth with data from space.\nSpire Global is a space-to-cloud analytics company that owns and operates the largest multi-purpose constellation of satellites.
