SRM Structures Design 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.

SRM Structures Design Engineer

DESCRIPTION

Long Wall is looking for an experienced Solid Rocket Motor (SRM) Structures Design Engineer to support the design, development, and production of SRMs for our interceptor system. This role is responsible for ensuring SRM motor cases, other primary structure, and secondary structure meet demanding missile interception requirements while maintaining manufacturability at scale. The SRM Structures Design Engineer serves as the technical authority for the design of SRM structural components. Responsibilities include design and analysis of motor cases, internal and external joints, raceways, flight equipment mounting, reviewing and interpreting static fire and flight test data, providing technical oversight and direction to suppliers, and defining requirements and verifying compliance throughout development and production. The successful candidate will establish rigorous design methods while driving efficient program execution. They will work closely with propulsion, ballistics, structures and dynamics, aerodynamics, guidance and control, manufacturing, and systems engineering teams to ensure structural design decisions remain aligned with system-level performance, technical baselines, and program objectives.

RESPONSIBILITIES:

• Design SRM structural components to meet technical requirements, including pressure vessels, vehicle primary structure, and secondary structures.
• Develop, refine, and validate design methods and tools for motor cases, igniter structure, and vehicle integration.
• Review and provide oversight to suppliers designing structural components for integration into the Cyclops vehicle.
• Review test data from component structural tests, including solid rocket motor static tests.
• Prepare, present, and explain technical results to government partners, customers, and suppliers.
• Other duties as assigned.

BASIC QUALIFICATIONS:

• Bachelor’s degree in engineering or a technical discipline, or equivalent experience in complex aerospace or defense development.
• 5+ years of experience with solid rocket motors or composite structures.

REQUIRED SKILLS AND EXPERIENCE:

• Proficiency with NX, Creo, or other parametric CAD software.
• Proficiency with product definition creation, including geometric dimensioning and tolerancing and engineering drawings.
• Experience with the design and development of filament-wound pressure vessels and other composite structures.
• Proven ability to operate effectively in fast‑paced environments that combine private‑investment‑driven development with government test requirements.
• Ability to interpret engineering artifacts, requirements, and configurations and convert them into actionable activities.
• Excellent organizational and communication skills; capable of aligning engineering teams, surfacing risks early, and maintaining clarity across disciplines.
• Demonstrated ability to partner closely across technical disciplines with technical authorities (chief engineering, systems engineering, mission assurance), customers, and suppliers to ensure disciplined technical execution.

PREFERRED SKILLS AND EXPERIENCE:

• Hands-on manufacturing experience with composite structures, including filament winding and hand lay-up.
• Proficiency in MATLAB, Python, C++, FORTRAN, or similar programming languages.
• Experience supporting missile defense, launch vehicle development, aerospace hardware integration, or other technically complex systems.
• Familiarity with requirements flow‑down, verification planning, ICD management, and configuration control.
• Prior experience working within a hybrid program environment (internal rapid development + government‑funded test campaigns).
• Ability to translate ambiguous technical requirements into executable work.

ADDITIONAL REQUIREMENTS:

• This position requires a national security suitability screening following offer acceptance.
• Ability to sit or stand for extended periods.
• Ability to use a computer for assignments and communicate effectively in person, via telepresence, and by phone.
• Ability to travel between Long Wall sites as needed.

ITAR Requirement This position requires access to information protected under US export control laws, including the International Traffic in Arms Regulations and/or the Export Administration Regulations. As such, US person status (including US citizens, U.S. permanent residents, individuals granted U.S. asylum status, or individuals admitted in U.S. refugee status) is a required qualification for this position. Equal Opportunity Employer We are an equal opportunity employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, national origin, protected veteran status, disability, genetics, or citizenship status (when otherwise legally authorized to work and access export-controlled data) and will not be discriminated against on the basis of such characteristics or any other status protected by the laws or regulations in the locations where we operate. We encourage applicants of all ages. National Security Suitability
Depending on the position, Long Wall may require the successful completion of a national security suitability screening in addition to its standard background check. Where required, the screening is conducted by Long Wall’s Facility Security Officer following offer acceptance and may include verification of any current or prior U.S. government security clearances or public trust positions. Information provided during the screening is used solely to determine suitability for the role and is held in confidence by Security. For positions subject to this requirement, any offer of employment is contingent upon a favorable suitability determination.
