  • Hands-on experience leading and executing component or subsystem tests, with a strong understanding of sensors, data acquisition systems, and control room operations, is required.
  • Experience writing test plans, developing test setups or fixtures, and performing structured post-test analysis is required.
  • Prior experience mentoring junior engineers or technicians, or serving as a technical lead, is required.
  • A strong understanding of safety processes, hazard analysis, and high-energy test operations is required.
  • The candidate must meet U.S. export control requirements as a U.S. citizen, permanent resident, asylee, or refugee.
  • The role requires working in an indoor manufacturing environment 70% of the time and outdoors 30% of the time.
  • The role requires travel among the Port of Long Beach (70%), El Segundo (20%), and other facilities (10%); occasional travel to other in-state and out-of-state sites may be required.
  • The role requires the ability to sit or stand for extended periods, use a computer to complete assignments, communicate with individuals and groups in person, by phone, and via telepresence, and pick up to 12 pounds.

Responsibilities

  • Lead development of test plans, procedures, instrumentation strategies, and data acquisition configurations for component, subsystem, and integrated system tests.
  • Design and refine test setups, fixtures, interfaces, and test stand elements in collaboration with mechanical, electrical, and guidance, navigation, and control teams.
  • Lead, mentor, and develop a small team of test engineers and technicians, providing technical guidance, feedback, and day-to-day support.
  • Assign and prioritize work across the team to meet program objectives and test schedules.
  • Build a culture of technical rigor, safety, ownership, and continuous improvement.
  • Oversee and participate in hands-on test execution, including setup, instrumentation, pre-test readiness, control room operations, teardown, and data review.
  • Ensure tests are executed safely and consistently through hazard analyses, procedural reviews, and operational readiness checks.
  • Validate test data quality and lead post-test analysis, reporting, and communication of results to engineering and program stakeholders.
  • Coordinate with engineering, manufacturing, and program teams to align test requirements, hardware readiness, and schedules.
  • Partner with test operations and facilities teams to ensure test stands, ground support equipment, and site infrastructure meet technical and operational needs.
  • Support anomaly investigations, root cause analysis, and implementation of corrective actions across test and engineering teams.
  • Drive continuous improvement in test documentation, procedures, and instrumentation reliability, including automation opportunities, data pipeline enhancements, and ongoing ground support equipment development.

Desired Qualifications

  • Experience with system-level, engine-level, or propulsion test campaigns.
  • Familiarity with real-time control systems, programmable logic controllers, automated test sequences, or custom data acquisition systems.
  • Experience designing or improving test stands, ground support equipment, or test site infrastructure.
  • Proficiency with Python, MATLAB, or similar tools for data processing and analysis.
  • Prior experience in a startup or high-growth hardware environment.
  • Experience with pyrotechnics, propulsion systems, hazardous operations, or flight test environments.
  • Knowledge of configuration management practices and structured test documentation systems.

About the Company

Long Wall

Produces hypersonic testbeds and defense interceptors

Long Wall repurposes its launch heritage to serve U.S. defense needs, building deployable space and missile-defense testing tools for the government. Its RSX is a hypersonic flight-test vehicle used as a test bed and threat-replication target, Ironwood is a containerized ground system for responsive launch, and Cyclops is a surface-launched interceptor designed to engage missiles in midflight. Unlike rivals pursuing commercial satellite launches, Long Wall focuses on U.S.-made defense hardware and offers an integrated set of launch/test and interception capabilities to shorten timelines and reduce costs. Its goal is to strengthen national security by providing ready-to-use, deployable defense testing and interception solutions for government customers.
