We are seeking a Special Test Equipment (STE) Designer responsible for the full lifecycle of interceptor test systems — from requirements analysis and qualification strategy through physical design, hardware build, and Low-Rate Initial Production (LRIP) deployment.

This role owns the realization of the interceptor test ecosystem across:

• Development benches
• Qualification fixtures
• Hardware-in-the-loop (HIL) systems
• Production acceptance stations

You will ensure that test systems provide rigorous requirements verification while also being physically robust, scalable, maintainable, and aligned with production rate targets. This is not solely a test planning role. It is a design–build–deploy ownership role
.

• Test Requirements & Architecture Ownership
  • Derive test equipment functional requirements from system and subsystem specifications.
  • Establish traceability between interceptor requirements and test coverage.
  • Define:
    • Subassembly test strategies
    • Qualification test configurations
    • Production acceptance test philosophy
    • Fault-injection and edge-case coverage approaches
  • Develop interface control documents (ICDs) between product and test systems.
  • Balance verification rigor with cycle time, cost, and rate considerations.
• Physical STE Design & Hardware Realization
  • Design complete STE hardware systems including:
    • Mechanical fixtures
    • Electrical interface panels
    • Breakout harnesses
    • Load simulators
    • Signal conditioning hardware
    • Test racks and enclosures
    • Generate full technical data packages:
      • Schematics
      • Wiring diagrams
      • Harness drawings
      • Mechanical CAD models
      • Assembly documentation
  • Select and integrate instrumentation (DAQ, power supplies, RF equipment, environmental interfaces).
  • Design safe high-voltage, high-current, and energetics-compatible test interfaces as required.
• Hands-On Build & Integration
  • Lead and directly support:
    • Rack assembly
    • Panel wiring
    • Harness fabrication
    • Fixture assembly
    • Hardware bring-up and debug
  • Conduct bench-level integration of hardware and automation software.
  • Debug electrical, mechanical, and software integration issues.
  • Validate signal integrity, power distribution, and system stability.
  • This role is expected to be present at the bench and on the floor during integration.
• Automated Test & Production Deployment
  • Develop automated test software (e.g., LabVIEW, Python, C++, etc.).
  • Architect production test stations optimized for:
    • Throughput
    • Repeatability
    • Operator simplicity
    • Error-proofing
  • Define takt-aligned test cycle times in coordination with Industrial Engineering.
  • Integrate STE into MES for data capture and traceability.
  • Lead factory installation and commissioning of LRIP test stations.
  • Drive rapid iteration and refinement during pilot and early production builds.
• Qualification & Environmental Test Support
  • Design and build fixtures and instrumentation for:
    • Vibration
    • Thermal
    • Shock
    • EMI/EMC
  • Support qualification campaigns with robust data acquisition strategies.
  • Lead root cause analysis of test anomalies.
  • Update STE configurations as designs mature.
• STE Lifecycle & Rate Scaling
  • Manage configuration control and revisions of test systems.
  • Improve test cycle time and reliability as production scales.
  • Establish maintenance, calibration, and sustainment strategies.
  • Drive cost-down efforts for production-deployed test systems.
  • Plan replication of test stations as rate increases.

• Bachelor’s degree in Electrical Engineering, Mechanical Engineering, Aerospace Engineering, or related discipline.
• 5+ years experience designing and building custom test equipment for aerospace,…
