Job summary

Thermon seeks a Senior Embedded Systems Engineer to join the R&D Controls and Accessories Team. You will own firmware from schematic review through production release for industrial control devices operating in harsh environments.

You will collaborate with hardware engineers, debug at the signal level, and implement robust interfaces, real-time control loops, and secure firmware practices. This role emphasizes ownership and cross-functional collaboration.

Qualifications

• 5+ years of professional embedded firmware experience.
• 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 (TouchGFX, LVGL, emWin, Embedded Wizard, or Qt for MCUs).
• 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.

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 factory acceptance test (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.
