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, technicians, and corporate professionals 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 those who take full responsibility for delivering flight-ready work while recognizing that no one succeeds alone. The best engineers, technicians, and corporate professionals 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.

PREFERRED SKILLS & EXPERIENCES:

Experience with aerospace component technologies, including spring-energized seals, bearings, and force balances, as well as test and qualification best practices.

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).

Familiarity with solenoid coil design processes and software (e.g., Maxwell).

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.

Demonstrated ability to write and execute test procedures for complex hardware operations.

Strong technical writing and communication skills for design reviews, test plans, and systems.

ADDITIONAL REQUIREMENTS:

Ability to sit or stand for extended periods of time

Ability to use a computer to complete assignments

Ability to communicate with individuals and groups in person, by phone, and telepresence

Ability to pick up to 12lbs

While performing the duties of this job, the employee will typically work in an office environment
