Propulsion Engineer

Job Description

Job Description

SPACEWORKS 

SpaceWorks Enterprises is an Atlanta-based aerospace R&D company pushing the boundaries of what's possible in high-speed flight systems, space operations, and advanced vehicle design. We work across the aerospace industry, from early-concept studies and multidisciplinary analysis to hardware prototyping and commercial software development. Our team delivers thoughtful and creative engineering solutions to customers including NASA, the Department of War, and leading commercial space organizations.

A DAY IN THE LIFE

The Propulsion Engineer will work within a small, multidisciplinary team of engineers on the design, analysis, development, and evaluation of advanced propulsion systems across a wide range of applications. The role spans the full product lifecycle, from early conceptual studies and trade space exploration through ground testing and flight system development. The balance of work shifts between analytical/design tasks and hands-on hardware activities depending on program phase and need. The successful candidate brings strong fundamentals in propulsion physics, fluid mechanics, and thermodynamics, and is comfortable moving fluidly between high-fidelity modeling at their desk and direct hardware support in the lab or at the test site. The position is full-time and will be located at our facilities in Atlanta, GA.

• Conduct conceptual and advanced propulsion design studies, including cycle analysis, performance trades, and system architecture assessments that may not progress to hardware
• Design, analyze, and evaluate propulsion system components — including thrust chambers, ignition systems, valves, insulation, and seals — from paper studies through fabrication and test, as program phase dictates
• Develop full-vehicle and subsystem thermal models capturing external heating environments, structural conduction, and internal temperature response
• Support mechanical, electrical, and fluid integration of propulsion system elements, including liquid propulsion systems, propellant tanks, and pressurization systems
• Participate in ground testing activities — including procedure development, execution, and data reduction — with hands-on involvement scaled to program needs
• Perform propulsion performance modeling and model validation against experimental data
• Communicate effectively with external suppliers, partners, and customers through written and verbal channels
• Brief customers across industry and U.S. government on program status, system performance, technical progress, and development roadmaps

• Must be a U.S. citizen and eligible to obtain a DoD Secret Security Clearance
  

BONUS POINTS IF YOU HAVE...  

• MS degree in Aerospace Engineering, Mechanical Engineering, or similar background
• 5+ years of relevant work experience in launch vehicle, aircraft, or spacecraft systems
• Hands-on experience in liquid rocket engine integration and testing
  
• Fundamental understanding of dynamic environments including shock, vibration, and acoustic loads
• Experience designing structures compatible with cryogenic and non-cryogenic fluids
• Experience with pipe/tube routing and/or flexibility analysis
• Proficiency with transient fluid network modeling including tools such as GFSSP and/or ROCETS
• Familiarity with modeling in Python, C/C++, Fortran and/or MATLAB
• Familiarity with aerospace fluid components (fittings, check valves, solenoid valves, relief valves, regulators, etc.)
• Familiarity with measurement devices (pressure transducers, thermocouples, RTDs, strain gages, etc.)
• Experience with GD&T per ASME Y14.5
• Desire to lead and manage individual contributors
