Senior Electrical Engineer - Power Electronics

Who We Are

Thermon 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.

We're looking for a Senior Electrical Engineer with deep power electronics expertise and full-stack PCB design capability to join our R&D Controls and Accessories team.

Our products, field‑deployed industrial controllers operating
-40°C to +85°C in explosive atmospheres, represent the state of the art in harsh‑environment power and control. Our roadmap pushes into territory where the easy reference designs don't exist: novel custom magnetics, and the certification burden that comes with deploying power switching and conversion hardware into hazardous locations.

This is an ownership role. You'll drive the full hardware arc from architecture through schematic, layout, bring‑up, DVT, and manufacturing handoff on a small team where every engineer's work ships to real products in the field.

• Are energized by power electronics problems that don't have a clean reference design to copy, where you have to reason from Maxwell's equations and magnetic simulation to a working transformer.
• Can own a board from blank schematic to production release without hand holding, and debug hardware failures at the signal level when bring‑up doesn't go as planned.
• Understand that industrial certification isn't a paperwork exercise, it's a design constraint that has to be baked in from schematic review, not bolted on at the end.
• Want to work on technology that's genuinely novel— not re‑implementing a reference design for the fifth time, but solving power extraction and conversion problems that have no off‑the‑shelf answer.
• Use AI tools as a force multiplier— for simulation cross‑check, datasheet mining, magnetics first‑pass, documentation— while applying rigorous engineering judgment to anything that touches a physical product.

• Power electronics architecture:
  Own the design of isolated power conversion systems—flyback, SEPIC, forward, resonant topologies—for microcontroller‑based industrial control hardware. Define the architecture from requirements, not from a reference design.
• Magnetic design:
  Design custom magnetics—transformers, coupled inductors, current transformers—including core selection, winding strategy, leakage inductance management, and thermal design. Validate in simulation and on the bench.
• Novel power extraction and conversion:
  Lead the investigation and productization of unconventional power source topologies— including coupler design, impedance matching, control strategy, and the full Haz Loc certification path for the resulting hardware.
• Analog and mixed‑signal design:
  Design isolated signal conditioning, precision current and voltage sensing, ground fault monitoring, analog front‑ends for RTD/thermocouple/4‑20mA inputs, and relay output stages that meet industrial operating requirements.
• PCB design:
  Own complete PCB designs in Altium Designer—schematic capture through layout— with proper attention to high‑voltage creepage/clearance, switching node containment, thermal dissipation, EMC, and IPC workmanship standards.
• Bring‑up and debug:
  Own board bring‑up from first power‑on through full functional verification. Debug switching converter instability, magnetics saturation, ground loops, EMC failures, and hardware‑firmware interface issues— with the right instrument and a systematic approach.
• Certification:
  Collaborate with the certifications team through CSA, UL, ATEX, and EMC testing. Understand what drives failures, propose design…
