Busek designs and builds spacecraft thrusters and the power electronics that drive them, covering Hall, electrospray, RF ion, pulsed plasma and green monopropellant systems. Its stack pairs mechanical CAD and simulation (SolidWorks, Creo, ANSYS) with embedded tooling (C++, RTOS, LabVIEW, Altium), and job posts point to bringing embedded software in-house and automating test. Hiring is engineering- and manufacturing-heavy at mid-level seniority.
Busek is a privately held propulsion manufacturer headquartered in Natick, Massachusetts, with 51–200 employees. The company develops thrusters across five propulsion technologies, sized for spacecraft ranging from cubesats to large geostationary satellites. Alongside thrusters it builds power processing electronics and spaceflight firmware. Its work includes support for Department of Defense programs, and operations span R&D, qualification testing and production manufacturing in the United States.
Busek uses SolidWorks, Creo, ANSYS, MATLAB, Python, C++, RTOS, LabVIEW, Altium Designer and LTspice for engineering, with Windchill, Teamcenter and Solidworks PDM for PLM, plus Epicor, Deltek, Power BI and Tableau.
Yes. Busek's open roles are concentrated in engineering and manufacturing, mostly mid-level, all in the United States, with steady hiring velocity.
Busek is building real-time firmware for spacecraft power and propulsion, hardware-in-the-loop testing, automated test and data acquisition frameworks, and new test capabilities for evolving propulsion technologies.
