In-Space Propulsion Lead

Key responsibilities

• Define the propulsion architecture for the group's products: thrust, Isp and mass trades, propellant and propulsion-class selection, feed system approach, dwell and refuelability.
• Lead build-versus-acquire-versus-partner decisions for propulsion: technical and production diligence on suppliers and acquisition targets, cost and schedule models, and a recommendation to the leadership team.
• Own the design, analysis, manufacturing plan, test plan and qualification of the selected propulsion systems, from thrusters through feed system, tanks and pressurization.
• Own propellant management over the mission life: thermal control, pressurization, leakage and propellant budgets.
• Establish propulsion test capability, from component to system-level hot fire, using existing Stoke infrastructure where it fits and specifying new capability where it does not.
• Provide propulsion inputs to mission design and vehicle architecture trades partnering with various leads to develop the full system.
• Lead root-cause investigations, risk mitigation, schedules and budgets for propulsion development.
• Help grow the propulsion team as the product matures.

Minimum qualifications

• Bachelor's degree in mechanical, aerospace or chemical engineering, physics or a related field.
• 10+ years of propulsion experience, including in-space propulsion flight hardware you were accountable for from design through qualification and flight.
• Hands-on experience with at least one class of in-space propulsion (chemical or electric) carried through qualification, and working knowledge of the others.
• Experience leading a propulsion team or program, with accountability for its technical output, schedule and budget.
• Strong fundamentals in combustion, heat transfer, fluid flow, and pressurization and propellant management systems.
• Experience owning test campaigns, from test plans through hot fire and anomaly resolution.
• Demonstrated ability to make rapid, well-reasoned propulsion architecture decisions with incomplete information.
• Excellent written and verbal communication skills.
• Ability to lead and to follow.

Preferred qualifications

• Experience across more than one propulsion class or thrust regime: high-thrust chemical (storable, green or cryogenic), electric, or multi-mode combinations.
• Propulsion for long-duration spacecraft (GEO, cislunar, multi-year LEO) where propellant management over the mission life drove the design.
• Experience with refueling interfaces, propellant transfer or depot concepts.
• Experience building and managing a propulsion engineering team, including hiring and standing up test and manufacturing capability.
• Master's degree or PhD in aerospace or mechanical engineering or a related field.
