Propulsion Engineer

Long Wall
Long Beach, CA Full Time
POSTED ON 3/24/2025
AVAILABLE BEFORE 5/24/2025

Long Wall Company was created in 2025 to accelerate missile defense technology for the U.S. and our allies. Building on the RS1 and GS0 launch systems, Long Wall develops containerized, mass-producible missile defense systems and offers rapid, low-cost flight testing. We believe that the future of global security and stability require defensive technology that is lower cost, higher performing, better tested, and more broadly distributed than is possible today. Join us.


Propulsion Engineers at Long Wall ensure the reliable operation of rocket engines and pressurization systems, delivering robust designs that perform seamlessly through all phases of flight. Their scope spans propellant management, pressurization, attitude control, pneumatics, and engine systems. A successful Propulsion Engineer takes full ownership—driving their system from concept to flight, integrating design, analysis, testing, and production into a streamlined, high-performance solution

\n


What we look for
  • Mission-Driven Problem Solvers. The aerospace frontier demands ingenuity. We want engineers who approach challenges with curiosity, embrace failure as a learning opportunity, and stay focused on delivering the best solution for the mission.
  • Total Ownership. We seek engineers who take full responsibility for delivering flight-ready work while recognizing that no one succeeds alone. The best engineers make their teammates better, knowing that complementary skills create force multiplication and drive mission success.


Responsibilities
  • Own the development of critical engine components (e.g., chamber, injector, turbopumps) and/or systems (e.g., pressurization, attitude control).
  • Define top-level engineering requirements aligned with business and mission objectives.
  • Identify and evaluate design strategies, selecting optimal approaches to meet performance requirements.
  • Perform system sizing and analysis using hand calculations, custom scripts, and advanced simulation tools.
  • Develop streamlined workflows, processes, and tools to enhance design and production efficiency.
  • Execute detailed design work, considering manufacturing, operational, and reliability constraints.
  • Lead product development, testing, qualification, and integration.
  • Develop production methodologies and support initial hardware builds.
  • Design and fabricate test hardware and production tooling to validate designs


Basic Qualifications
  • B.S. in any engineering discipline from an accredited university
  • 5 years of industry experience in a design, development, or systems role


Preferred Skills and Experience
  • Proficiency in CAD design software (e.g., NX, CATIA, CREO/Pro-E
  • Strong analytical capability using hand calculations and finite element analysis tools (e.g., ANSYS, ABAQUS, NASTRAN)
  • Firm understanding of manufacturing processes, GD&T, and DFM principles.
  • Ability to develop scripts in Python or MATLAB for automation and analysis.
  • Strong understanding of compressible/incompressible flow dynamics and thermodynamics.
  • Experience designing, fabricating, and testing aerospace hardware, including fluid systems at high pressures and extreme temperatures.
  • Demonstrated ability to write and execute test procedures for complex hardware operations.
  • Strong technical writing and communication skills for design reviews, test plans, and system documentation.
