• Knowledge of thermodynamic principles, compressible flow dynamics, and structural design.

• Experience with commercial 3D design software such as SolidWorks, NX, Creo, or others.

• Proficiency in GD&T and basic manufacturing principles.

• Experience working with common propulsion/fluid system components including, but not limited to, valves, regulators, pressure transducers, pumps and tanks.

• Experience developing and working with plumbing and instrumentation diagrams.

• Strong verbal and written communication skills.

• Ability to work in an entrepreneurial, fast-paced, and matrixed cross-functional environment.

• Willingness to learn and adapt to new technologies and processes.

What makes you stand out:

• 5+ years of experience with spacecraft fluid systems design.

• Hands-on experience with high-pressure, high-energy or hazardous fluid systems.

• Experience with spacecraft propulsion, including green or non-green storable propellants.

• Advanced thermal or fluid analysis experience (e.g. ANSYS, Thermal Desktop).

• Experience with fluid component ownership, including for example thrusters, valves, regulators, pumps or combustion devices.

• Basic knowledge of satellite operations and subsystems.

Benefits:

• Health insurance (100% coverage for individuals, 80% for families).

• Vision & Dental Insurance.

• Company paid life, AD&D, and disability insurances.

• Voluntary Life Insurance.
