Fluid Components Engineer

Long Wall Company was created in 2024 to accelerate missile defense technology for the U.S. and our allies. We specialize in ballistic missile defense and are developing Cyclops, a low-cost, mass-producible interceptor. We also produce containerized launchers and offer low-cost targets for threat replication. The future of global security depends on defensive technology that redefines cost, magazine depth, and distribution to deter and defend against evolving threats. Join us.  

WHAT WE LOOK FOR

Mission-Driven Problem Solvers – The problems in missile defense demand 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.

Fluid Components Engineer 

Aerospace components require operation in extreme environments – high temperature, low temperature, high pressure, high vibration, high shock – and they must operate with absolute certainty. Whether it be a separation mechanism between stages or a solenoid valve controlling engine operation, Long Wall designs, produces, and tests the majority of its components in-house, and requires top talent to do so.    

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 related design or development role.
