Job Description

Who We AreThermon is a global industrial technology leader and the world's foremost provider of mission-critical heating solutions. From power generation and semiconductors to oil & gas and food processing, our systems keep essential industries running safely, efficiently, and reliably.We don't just make heaters, we deliver complete, end-to-end solutions that include design, installation, controls, and monitoring. Our people and products transfer the warmth needed to make life work.Headquartered in Austin, Texas, and operating in 18 countries, Thermon is built on the values of Care, Commit, and Collaborate. We're a team of innovators and problem-solvers, united by our mission and driven by a culture of ownership and impact. Who We WantWe're looking for a Senior Embedded Systems Engineer to join our R&D Controls and Accessories Team and help build the next generation of industrial control hardware and IIoT-connected devices. Our products operate in harsh industrial environments around the world, where reliability isn't a feature, it's a requirement.This role is ideal for someone who lives closest to the metal, fluent in C/C++ and real-time firmware, comfortable reasoning about signal integrity, power budgets, and hardware-software boundaries, but who can also bridge up to communication protocols and connectivity layers to shape how our devices integrate into modern IIoT platforms. You'll own firmware from schematic review through production release. You'll thrive here if you:· Want to make a real impact on a small, empowered team.· Enjoy building a product that solves real-world problems and improves continuously through customer feedback.· Are energized by the challenge of integrating industrial controls hardware into a modern software platform.· Love designing elegant systems and modeling complex data.· Take pride in writing clean, maintainable, and performant code.· Leverage modern AI tools and workflows as a force multiplier, using them to move faster, reduce rework, and raise the quality bar from the first commit. What You'll Do· 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. What You Bring· 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) as well as 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.· Bachelor's degree in Electrical Engineering, Computer Engineering, or related field. Bonus Points For· Experience with hardware certification processes (CSA, UL, CE, EMC/EMI testing).· Familiarity with IIoT connectivity and cloud integration (MQTT, Azure IoT Hub, AWS IoT Core).· Experience with Altium Designer for PCB design review or DFT feedback.· Knowledge of functional safety principles (UL60730, UL61010) or hazardous location (HazLoc UL60079) design requirements.· Experience developing factory acceptance test/production test.· Familiarity with containerization and DevOps tooling (Docker, Jenkins, CI/CD pipelines).· Experience with bootloader development and secure firmware update (OTA) mechanisms. Why You'll Love Working at Thermon· Team Impact: Small, agile team where your contributions ship to real products in the field.· Global Reach: Your work will power critical infrastructure around the world.· Full Product Ownership: Work from concept validation through certification and manufacturing release.· Collaborative Culture: Cross-functional teams that value engineering rigor, creativity, honest feedback, and continuous improvement.· Comprehensive Benefits: Competitive salary, health coverage, 401(k) with match, and more.· Austin-Based: Work in one of the most vibrant tech hubs in the country. Join us!
