Full Job Description

Primary Responsibilities

  • Take a customer-designed physical DUT (electrical, mechanical, or electromechanical) and determine what must be proven about it
  • Connect and configure bench instrumentation (oscilloscopes, spectrum/power analyzers, signal/waveform generators, NI hardware, multimeters, power supplies) to the DUT
  • Write custom test automation and analysis software in Python and/or LabVIEW to control the test setup and interpret results
  • Develop hardware-in-the-loop (HIL) test environments and simulation to validate the DUT under realistic conditions
  • Build operator-facing GUIs so engineers or technicians can run the test
  • Establish and validate repeatable, calibrated, NIST-traceable test data
  • Maintain and improve existing automated test systems, fixtures, and instrument drivers
  • Support configuration management for test software and system architecture across platforms
  • Train engineers and technicians on running the automated test systems you build
  • Engage with customers to understand testing needs, demonstrate capabilities, and support business development
  • Document test procedures, system architecture, and requirements, including:
    • Test and inspection requirements documents
    • Multimedia/user documentation for the test system
    • System documentation for hardware and software components
    • Test program style guides and GUI/architecture updates for current and next-generation systems
  • Attend meetings and reviews; communicate with the program manager, engineers, and customer team members.
  • Communicate with external parties such as mission partners and vendors.

Required Qualifications:
  • Active TS/SCI; must be eligible and willing to upgrade to TS/SCI w/polygraph.
  • Bachelor of Science degree, preferably in an engineering field, and at least 8 years of relevant experience, or Master's with 6–10 years; at least 12 years of work experience can be used in lieu of degree/combined with education.
  • Demonstrated hands-on experience taking a physical DUT (electrical/mechanical hardware) and building a custom automated test system around it — not testing an existing software product.
  • Demonstrated experience with bench test equipment from Agilent, Keysight, HP, Tektronix, and National Instruments, including power supplies, multimeters, oscilloscopes, counters, power meters, signal & waveform generators, electronic loads, and audio/noise/signal/modulation/power analyzers.
  • Working knowledge of Python and/or LabVIEW used to write custom test automation, instrument drivers, and analysis for hardware.
  • Understanding of measurement traceability, calibration, and repeatable test data (NIST-traceable).
  • Demonstrated experience/training operating electronic devices such as transmitters, receivers, and power supplies.
  • Strong written/verbal communication skills, including the ability to document systems, train others, and work directly with customers.
  • Able to work well independently and as part of a team.

 

Desired Qualifications
  • Experience with hardware-in-the-loop (HIL) test environments and simulation
  • Experience building custom operator-facing GUIs or test dashboards for a DUT
  • Experience with FPGAs, embedded systems, or microcontrollers
  • Experience with test fixtures and custom instrument drivers
  • Knowledge of RF principles and hands-on RF test experience
  • Knowledge of cellular technologies and/or cellular testing experience
  • Experience writing scripts to test or interface with robotic systems
  • Background in manufacturing test, validation engineering, or a test and inspection (T&I) environment
  • Knowledgeable of electronics and electrical engineering principles (voltage, current, RF)
  • Experience with customer-facing roles, technical training delivery, or business development support
