Senior-Principal Embedded Systems Engineer – Hardware - Firmware

At Panduit, we don’t just offer a job, we offer a career where your contributions directly impact on our customers, the environment, and our company’s success. You’ll have the opportunity to grow, innovate, and be part of an inclusive team that celebrates both individual and collective achievements.

The Senior Embedded Systems Engineer develops the embedded hardware and firmware that enables Panduit’s advanced power-electronics prototypes and proof-of-concept systems. This hands-on role owns embedded firmware development for prototype control, sensing, communications, protection, diagnostics, and system operation, while also contributing to analog/digital circuit design and hardware bring-up. The engineer works closely with the Power Electronics team to develop, integrate, debug, and demonstrate complete working prototypes.

What You Will Do

• Develop embedded firmware in C/C++ for microcontrollers used in power-electronics prototypes and proof-of-concept systems.
• Develop and integrate low-level drivers and interfaces for ADCs, PWM/timers, GPIO, SPI, I2C, UART, CAN, Ethernet or single-pair Ethernet, and other required peripherals.
• Implement prototype control sequencing, state machines, communications, telemetry, diagnostics, protection, and fault-management functions.
• Develop firmware and simple software tools needed to bring up, operate, characterize, and demonstrate power-electronics prototypes.
• Work directly with Power Electronics Engineers to integrate firmware with PFC, DC/DC, sensing, protection, load-sharing, communications, and system-control hardware.
• Design embedded and mixed-signal hardware including MCU circuitry, analog sensing, signal conditioning, isolation, communications interfaces, auxiliary supplies, and board-level protection.
• Perform tolerance, accuracy, noise, bandwidth, timing, and worst-case analyses for sensing and control circuits.
• Create schematics and work with PCB designers on grounding, partitioning, isolation, signal integrity, power integrity, EMI/EMC, and design-for-test.
• Lead board bring-up and debug hardware-firmware interactions using oscilloscopes, logic analyzers, debuggers, trace tools, DMMs, programmable supplies, and related laboratory equipment.
• Develop diagnostic firmware, test utilities, scripts, or simple PC-based tools as needed to accelerate prototype development and system troubleshooting.
• Support prototype characterization, fault injection, design reviews, test-plan development, and documentation of firmware, hardware interfaces, test results, and design rationale.
• Collaborate closely with U.S. R&D Team and local team members to resolve system-level issues and deliver reliable, demonstrable PoC systems.

What You Will Bring

• Bachelor’s degree in Electrical Engineering, Electronics Engineering, Computer Engineering, or a related discipline.
• Typically 8+ years of embedded systems development experience with substantial hands-on firmware responsibility.
• Strong hands-on embedded firmware development experience using C/C++ on microcontrollers, including peripheral drivers, real-time control, communications, diagnostics, and hardware-firmware debugging.
• Experience developing firmware around ADCs, PWM/timers, GPIO, SPI, I2C, UART, CAN, Ethernet-class interfaces, or similar embedded peripherals.
• Strong practical knowledge of analog and mixed-signal circuits, including op-amps, comparators, signal conditioning, filtering, sensing, ADC/DAC interfaces, protection, and isolation.
• Experience designing MCU- or processor-based hardware and integrating firmware with custom electronic hardware.
• Experience with professional ECAD tools such as Altium Designer or equivalent.
• Hands-on experience with oscilloscopes, logic analyzers, DMMs, programmable supplies, JTAG/SWD debuggers, and prototype rework/debug methods.
• Ability to independently develop, bring up, troubleshoot, and document embedded hardware and firmware for complex prototypes.
• Strong analytical, communication, documentation, and teamwork skills.

Preferred Qualifications

• 10+ years of embedded systems, embedded firmware, or mixed-signal product-development experience.
• Experience developing embedded control and diagnostics for power converters, industrial equipment, energy systems, or other electrically noisy environments.
• Experience with RTOS-based systems, bootloaders, firmware update mechanisms, or embedded communications stacks.
• Experience with digital power control, PWM generation, high-speed ADC sampling, protection logic, or state-machine development for power-electronics systems.
• Experience with galvanic isolation, high-voltage sensing, precision current measurement, or safety-related diagnostic circuits.
• Experience with Ethernet, CAN, RS-485, single-pair Ethernet, or other industrial communications.
• Experience with Python or similar scripting for test automation, diagnostics, or data analysis.
• Experience with EMI/EMC troubleshooting, functional-safety concepts, or hardware/firmware fault-injection testing.
