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 Senior 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
