Parallel Systems is hiring a Vehicle Integration Test Engineer

About the Role

Parallel Systems is hiring a Vehicle Integration Test Engineer to own vehicle validation at the contract manufacturer and in the field. This role sits at the intersection of systems engineering, hardware validation, and factory operations, ensuring our systems meet performance, safety, and regulatory requirements before release.

What You'll Do

  • Own vehicle-level and subsystem validation activities, including factory vehicle checkouts, subsystem acceptance testing, site acceptance testing, and manufacturing support.
  • Plan and execute system integration and validation campaigns across mechanical, electrical, controls, and embedded software systems.
  • Work with Responsible Engineers to decompose top-level system requirements into actionable test requirements and verification plans.
  • Manage and maintain requirements traceability from system requirements through validation evidence using a structured requirements database.
  • Develop end-of-line factory test processes, tooling requirements, and documentation in partnership with Contract Manufacturer engineers.
  • Design, build, and maintain test stands and related validation infrastructure.
  • Define and document test procedures, test reports, and compliance artifacts with a high level of rigor and attention to detail.
  • Ensure hardware systems, including firmware and software interfaces, are tested correctly prior to vehicle release from the Contract Manufacturer.
  • Translate engineering and integration efforts into clear regulatory and safety documentation aligned with governing standards.
  • Collect, organize, and review vendor and manufacturing quality documentation.
  • Provide feedback across the design lifecycle to improve testability, reliability, and system robustness.

What We're Looking For

  • Bachelor’s or Master’s degree in Mechanical Engineering, Electrical Engineering, Robotics, Controls, Aerospace, Computer Science, or a related field.
  • 5+ years of experience working on complex hardware systems.
  • Direct experience testing electromechanical systems that integrate hardware, firmware, and software interfaces.
  • Strong foundation in electromechanical fundamentals and system integration.
  • Experience with system and subsystem validation such as acceptance testing, environmental validation, integration testing, and deployment testing.
  • Experience working in a hardware lab, fabrication, maintenance, or factory environment.
  • Demonstrated ability to create structured, audit-ready documentation for safety and compliance purposes.
  • Willingness to travel up to 50%.

Nice to Have

  • Experience with production end-of-line testing in a factory setting.
  • Experience with classical systems engineering practices including requirements management, functional architecture, and DFMEA.
  • Experience managing or administering a requirements database and maintaining verification traceability.
