Job summary

Thermon Industries, Inc is seeking a Senior Embedded Systems Engineer to join the R&D Controls and Accessories Team to build next‑gen industrial control hardware and IIoT devices.

You’ll own firmware from schematic review through production release, work with hardware teams, and tackle signal-level debugging to ensure reliability in harsh environments. Expect hands‑on firmware in ARM Cortex‑M targets, RTOS, and modern connectivity stacks.

Qualifications

• 5+ years of professional experience developing embedded firmware for production hardware products.
• Strong proficiency in C and C++ for microcontroller targets (ARM Cortex-M, STM32, or similar) and Python for test.
• Hands-on experience with RTOS environments (FreeRTOS, Zephyr, or equivalent) and GUI Toolkits.
• Solid understanding of embedded fundamentals: interrupts, timers, DMA, GPIO, UART/SPI/I2C, ADC/DAC.
• Experience debugging hardware-firmware issues using oscilloscopes, logic analyzers, and JTAG/SWD debuggers.
• Familiarity with industrial communication protocols (Modbus, CAN Bus, RS-485, BACNet).
• Experience reading and reviewing schematics and PCB layouts (Altium Designer or equivalent).
• Understanding of firmware release processes, version management, and manufacturing handoff.
• Bachelor's degree in Electrical Engineering, Computer Engineering, or related field.

Responsibilities

• Develop and maintain production-quality firmware in industrial control devices.
• Collaborate with hardware engineers during schematic review, board bring-up, and design validation.
• Debug hardware-firmware interaction issues at the signal level (scoping, logic analysis, fault isolation).
• Implement and maintain user-friendly and highly responsive user interfaces, real-time control loops, watchdog circuits, and safe operating state machines.
• Integrate and extend support for industrial communication protocols (Modbus RTU/TCP, CAN Bus, MQTT, RS-485) as well as Ethernet, USB, and common 2.4GHz wireless stacks.
• Develop and maintain production test firmware and FAT tooling for manufacturing handoff.
• Manage firmware releases through version control.
• Contribute to system documentation and architectural clarity.
• Drive best practices through code reviews, mentorship, and continuous improvement on a cross-functional team.
