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 (e.g., 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
Qualification
Required
Bachelor's degree in Electrical Engineering, Computer Engineering, or closely related field
Minimum five (5) years of experience
Embedded programming experience in C/C++ on microcontrollers or embedded Linux (device bring-up, drivers, peripherals, timing)
Experience developing or integrating hardware + firmware systems, including board-level interfaces and real-world debugging
Comfort with common digital interfaces (SPI/I2C/UART/CAN/Ethernet) and using test equipment to validate signals and timing
Ability to work from requirements to implementation: scoping, designing, building, testing, and documenting
Preferred
Experience with hardware-in-the-loop (HIL), simulators, emulators, or automated test stands for complex systems
FPGA familiarity (even at an integration level), high-speed interfaces, or mixed-signal design (ADC/DAC selection, anti-aliasing, clocking)
Device driver development, kernel modules, or low-level Linux performance/timing optimization
Familiarity with at least one embedded environment: bare-metal, RTOS (e.g., FreeRTOS), or embedded Linux
Experience with networking and time synchronization concepts (PTP, NTP), data logging pipelines, or telemetry protocols
