We have an exciting opportunity available for a seasoned spacecraft thermodynamics/fluids engineer to support our team located in Englewood, CO. The Senior Spacecraft Thermodynamics/Fluids Engineer will support the development of satellite systems with the responsibility of developing technical solutions for the long-term objectives of the Division, while serving as a mentor and thought leader for our growing team of engineers

This Thermodynamics/Fluids Engineer will support all phases of assigned engineering programs from inception through completion. The successful candidate will be able to navigate disciplines outside of thermodynamics engineering and must collaborate effectively with technical staff, program managers and engineering management. Strong and confident decision-making ability is essential.

DUTIES AND RESPONSIBILITIES:

• Ability to analyze spacecraft, aerospace or mechanical components
• Analysis of gas/liquid propulsion monopropellant and bi-propellant components/subassemblies into gas and liquid propulsion subsystems.
• Lead the analysis and optimization of spacecraft fluid systems, with a focus on propulsion, slosh dynamics, plume impingement and aerophysics.
• Perform advanced simulations and modeling of fluid behavior in spacecraft environments, including zero-gravity, extreme temperature variations, and vacuum conditions.
• Develop and validate fluid system designs for both current and future spacecraft, considering mission-specific needs and operational challenges.
• Leverage mechanical engineering background within the fundamental areas by designed aerospace vehicle structures and spacecraft.
• Provide technical leadership in the design and testing of fluid systems, including defining requirements, selecting materials, and developing test plans.
• Mentor junior engineers and provide technical guidance to enhance team performance and knowledge.
• Prepare detailed reports, technical documentation, and presentations for stakeholders and management.
• Stay up-to-date with the latest developments in fluid dynamics, spacecraft technologies, and industry standards.

We recognize and appreciate the value and contributions of individuals with diverse backgrounds and experiences and welcome all qualified individuals to apply.
