AI Summary

Designs, produces, and tests aerospace fluid components for missile defense systems, ensuring they operate reliably in extreme environments from ideation through field support.

About this role

Long Wall Company was created in 2024 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.
What we look for
Mission-Driven Problem Solvers. The aerospace frontier demands ingenuity. We want Team members 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 staff and engineers who take full responsibility for contributing to and delivering flight-ready work while recognizing that no one succeeds alone. The best engineers, corporate professionals, and technicians 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

  • Total ownership of Long Wall components, from ideation through design, manufacturing, qualification, and field support.
  • Ensuring launch vehicle, interceptor, and ground system design utilizing components properly consider the environmental and performance bounds of those components.
  • Mentorship of less experienced engineers and coworkers, both within and without the components group, to ensure all have the correct toolset for design and use of components at Long Wall.

    • 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 and Experience

  • 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.

    • 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
