We are seeking a highly skilled Propulsion Engineer to lead the design, analysis, integration, and testing of propulsion systems for our LEO satellite missions. The ideal candidate brings a deep understanding of electric and/or chemical propulsion systems and has hands-on experience in full lifecycle spacecraft development.
As such, we have an intense culture of curiosity, hunger, and results.
If you want a typical 9-5 job, this is not the place for you
You do not need to meet 100% of the preferred qualifications to be considered. We encourage anyone who meets the basic qualifications and is interested in the role to apply – we are looking for enthusiastic, dedicated people to join our team, and want the opportunity to talk to you!Responsibilities:
· Design, and trade studies of satellite propulsion systems (chemical, electric).
· Conduct performance modeling, plume analysis, and mission-specific delta-v calculations.
· Manage propulsion subsystem integration with satellite bus, including mechanical and thermal interfaces.
· Develop detailed propulsion system budgets (mass, power, delta-v, etc.).
· Oversee procurement and qualification of thrusters, valves, tanks, Thruster Control Units and feed systems.
· Define and review test plans for propulsion systems – from component-level to integrated hotfire and system testing.
· Support propulsion operations during AIT (Assembly, Integration & Testing) and post-launch commissioning.
· Interface with vendors, launch providers, and cross-functional teams (GNC, ADCS, Thermal, Systems).Qualifications:
· Bachelor’s or Master’s degree in Aerospace, Mechanical Engineering, or a related field (PhD preferred for research-focused roles).
· 2+ years of hands-on experience in propulsion system design, preferably in space missions.
· Proficiency in tools such as MATLAB, Python, ANSYS, CAD (SolidWorks, NX), and fluid dynamics software.
· In-depth knowledge of satellite propulsion options (monopropellant, bipropellant, electric propulsion such as HET, GIE, FEEP, etc.).
· Experience with flight hardware development, testing, and qualification processes.
· Familiarity with industry standards such as ECSS, NASA GEVS, or MIL-STD.
· Excellent problem-solving, documentation, and cross-functional collaboration skills.Preferred Experience:
· Direct experience with low-thrust mission design or Electric Propulsion orbit-raising strategies.
· Understanding of contamination control and plume interaction for precision payloads.
· Previous involvement in satellite launch campaigns or in-orbit anomaly resolution.
