Electrical Engineer – Embedded Programming (Hardware Simulators / HIL Testbeds)

Overview

We’re seeking an Electrical Engineer with strong embedded programming skills to design, build, and maintain hardware simulators and hardware-in-the-loop (HIL) testbeds used to validate real-world systems before they reach the lab, range, or field. You’ll work at the intersection of electronics, firmware, and test automation; creating simulation hardware, interface boards, and real-time control / monitoring software that makes system testing faster, safer, and more repeatable.

If you enjoy hands-on lab work, debugging across hardware + firmware boundaries, and building tools that other engineers rely on every day, this role will feel right.

Pay Range $104,000 - $182,000

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

• Design and integrate hardware simulators that replicate real equipment behavior in a lab environment.
• Develop embedded software / firmware to control simulator hardware, generate stimuli, capture telemetry, and implement real-time behaviors.
• Build and maintain HIL testbeds : wiring, configuration management, automated bring-up, calibration, and test execution workflows.
• Create test utilities and automation (Python / C / C++ preferred) to run scenarios, log data, generate reports, and support regression testing for hardware.
• Design interface circuitry and harnessing for common buses and I / O (., SPI / I2C / UART / CAN, Ethernet, GPIO, ADC / DAC, PWM, discretes).
• Use lab instrumentation (oscilloscope, logic analyzer, spectrum analyzer) to debug timing, signal integrity, and protocol-level issues.
• Author clear engineering artifacts : schematics, interface control docs, test procedures, software readmes, and troubleshooting guides.
• Collaborate with systems, software, and test teams to translate requirements into simulator capabilities and verification coverage.
