Senior Engineer - Propulsion Systems

Impulse Space is building the next generation of in-space transportation. As a Senior Engineer - Propulsion Systems, you will lead the development of high-performance spacecraft propulsion systems from clean-sheet concept through on-orbit operations.

You will be the Responsible Propulsion Engineer for one of our in-space propulsion systems, which may include bipropellant thrusters, pressure vessels, fluid systems, mechanical hardware, electrical interfaces, and flight or ground software.

This is a highly hands-on, cross-functional role for an engineer who can set technical direction, make sound system-level decisions, and deliver hardware in a fast-paced environment. ## Responsibilities - Own propulsion system development across requirements, architecture, design, analysis, implementation, integration, test, and flight operations. - Lead system-level trades involving fluids, thermodynamics, heat transfer, materials, mechanical design, and operations. - Define system requirements, interfaces, verification strategies, and configuration baselines. - Plan and execute development, acceptance, and qualification test campaigns. - Define build and test scope, sequence of operations, readiness criteria, and technical milestones. - Review test and flight data, investigate anomalies, and drive corrective actions to closure. - Identify technical and programmatic risks and develop practical mitigation strategies. - Provide on-orbit support, including propulsion performance assessment and anomaly resolution. - Partner closely with manufacturing, integration, test, and mission operations teams to deliver reliable, integrated systems. - Communicate technical decisions, status, and risks to internal and external stakeholders. - Mentor engineers and raise the technical standard of the propulsion organization. ## Minimum Qualifications - Bachelor’s degree in engineering, physics, or a related technical discipline. - 5+ years of professional experience in aerospace propulsion or a closely related field for the Senior level; Staff-level candidates will typically have broader technical leadership experience. - Demonstrated experience developing bipropellant rocket propulsion systems . - Strong foundation in fluid mechanics, thermodynamics, heat transfer, mechanics, and materials. - Experience performing system-level engineering trades, including thermal-fluid analysis, materials selection, component selection, and operational analysis. - Experience owning technical work from requirements definition through implementation and verification. - Ability to lead effectively in small, highly collaborative, cross-functional teams. - Strong written and verbal communication skills. ## Preferred Skills and Experience - Experience serving as the responsible engineer or technical lead for a flight propulsion system. - Experience with spacecraft propulsion-system architecture. - Experience with pressure systems, propellant management, valves, regulators, tanks, thrusters, or feed systems. - Experience developing or executing propulsion development, acceptance, or qualification tests. - Experience supporting launch or on-orbit spacecraft operations. - Experience leading anomaly investigations, root-cause analysis, and corrective-action implementation. - Experience mentoring engineers or establishing technical processes and best practices. - For Staff-level candidates: a demonstrated record of setting technical direction, influencing across organizations, and delivering complex systems with limited oversight. ## Why Impulse Space?

You will have the opportunity to work on flight hardware that enables responsive, reliable movement in space - while solving challenging propulsion problems alongside a highly capable team. At Impulse, your work will directly influence spacecraft performance, mission success, and the future of in-space transportation. Compensation bands are determined by role, level, location, and alignment with market data.

Individual level and base pay is determined on a case-by-case basis and may vary based on job-related skills, education, experience, technical capabilities and internal equity. In addition to base salary, for full-time hires, you may also be eligible for long-term incentives, in the form of stock options, and access to medical, vision & dental coverage as well as access to a 401(k) retirement plan.
