Portalsystems
Senior Spacecraft Propulsion Test Engineer
Portalsystems, Bothell, Washington, United States, 98021
We are seeking a highly skilled Propulsion Engineer with extensive experience in spacecraft propulsion systems, particularly in analysis and testing within high-vacuum environments. The ideal candidate will have expertise in testing systems using storable propellants. Proficiency in propulsion modeling software, including ROCETS, TDK, and other industry-standard tools, is preferred.
Responsibilities
Design, analyze, and optimize spacecraft propulsion systems with a focus on storable propellants.
Conduct and oversee testing of propulsion systems in high-vacuum environments, ensuring system performance, reliability, and safety.
Utilize propulsion modeling software (e.g., ROCETS or TDK) to simulate and validate system performance.
Work with storable propellants in test and operational environments.
Develop and execute test plans, procedures, and data analysis for propulsion system development, qualification and acceptance.
Collaborate with test facility teams to ensure safe and efficient handling of hazardous propellants.
Support system-level trade studies, mission planning, and anomaly resolution related to propulsion performance.
Prepare and present technical reports, documentation, and findings to stakeholders, including internal teams and external partners.
Mentor junior test engineers and technicians.
Basic Qualifications
Master’s, or Ph.D. in Aerospace Engineering, Mechanical Engineering, or a related discipline.
Proven experience in spacecraft propulsion system design, analysis, and testing, specifically with storable propellants.
Expertise in propulsion modeling and simulation tools (e.g., ROCETS, TDK, or other).
Strong understanding of fluid dynamics, thermodynamics, and combustion processes in spacecraft propulsion.
Hands-on experience with high-vacuum test facilities and propellant handling procedures for hazardous chemicals.
Knowledge of thruster performance evaluation, reaction control systems (RCS), and main engine applications.
Strong ability to work in cross-functional teams and communicate complex technical concepts effectively.
Preferred skills & Experience
Experience with electric propulsion, hybrid propulsion systems, or green monopropellants.
Knowledge of mission design, orbital mechanics, and spacecraft system integration.
Familiarity with regulatory standards, safety protocols, and industry best practices for hazardous propellant handling and spacecraft propulsion.
