Hardware Simulator Engineer/Operator

Overview

We're seeking a Hardware Simulator Engineer / Operator to support the operation, troubleshooting, and sustainment of hardware simulators and hardware-in-the-loop (HIL) testbeds in both laboratory and field environments. You will be hands-on with real equipment, setting up systems, running test scenarios, collecting and validating data, and ensuring simulator availability for customer demos, developmental testing, and field events.

This role is ideal for someone who enjoys practical engineering, disciplined execution, and fast-paced troubleshooting, from cable-level issues and timing faults to configuration control and field logistics.

Pay Range $85,000 - $163,000

The pay range for this position is a general guideline only and not a guarantee of compensation or salary. Additional factors considered in extending an offer include (but are not limited to) responsibilities of job, education, experience, knowledge, skills, and abilities, as well as internal equity, alignment with market data, geographic location, and any applicable laws

Responsibilities

• Operate hardware simulators and HIL testbeds in the lab and during field deployments; execute test plans and scenarios safely and repeatably.
• Perform system setup and teardown: rack integration, power-up/power-down procedures, cabling/harnessing, configuration loading, and pre-test checks.
• Monitor simulator health during runs (telemetry, logs, built-in tests); identify anomalies and take corrective action to keep events on track.
• Troubleshoot hardware and integration issues across power, I/O, networking, timing, and sensors/actuators; coordinate fixes with engineering teams.
• Calibrate and verify simulator outputs/inputs using lab instruments (oscilloscope, logic analyzer, DMM, power supplies) and documented procedures.
• Maintain configuration control: versions, wiring diagrams, asset inventory, spares, and change tracking for lab and field baselines.
• Collect, label, and validate test data; produce run notes, quick-look results, and issue summaries for after-action reviews.
• Support logistics for field events: packing, transport, site setup, environmental checks, and compliance with customer/site safety rules.
• Contribute to documentation: operator checklists, test procedures, troubleshooting guides, and training materials.

Qualifications

• BS in Engineering/Engineering Technology/Computer Science (or equivalent practical experience).
• 2 years of experience
• Working knowledge of common interfaces and networks (Ethernet, serial/UART, CAN, GPIO; SPI/I2C a plus).
• Proficiency with Windows and/or Linux; comfortable with command line tools and basic scripting for setup/log collection (Python/Bash helpful).
• Experience troubleshooting with standard lab tools (DMM, oscilloscope, logic analyzer) and interpreting logs/telemetry.
• Comfort with cables/harnesses, connectors, rack equipment, and safe power practices; able to follow detailed procedures and checklists.
• Strong documentation habits and communication skills; able to produce clear run notes and concise issue reports.
• Ability and willingness to travel for field events and work flexible hours during test windows (including early/late shifts or occasional weekends as required).

Nice to have

• Experience with HIL environments, automated test stands, or simulator operation for complex systems.
• RF/EW/sensors experience; familiarity with timing/synchronization, data acquisition, or telemetry systems.
• Hands-on electronics skills: reading schematics, basic rework/repair, harness fabrication, connector pinouts.
• Scripting/automation to streamline operations (Python, Bash, PowerShell) and basic data triage/quick-look plots.
• Experience with environmental and field constraints (mobile racks, generators, shelters, ruggedized equipment).

Field readiness

• Ability to lift/carry up to 50 lbs and safely handle racks/cases with appropriate equipment and team support.
• Ability to work outdoors or in varying environments during field tests (temperature, dust, noise).
• Valid driver's license.

Security requirements

• Citizenship: U.S. citizenship required
• Clearance: Active Secret required
