About The Position

Miller Electric Mfg. LLC, a leading U.S. designer and manufacturer of welding equipment, is growing its Central Engineering team. We are looking for a Senior Power Electronics & Controls Engineer who's deep power electronics instinct is backed by solid control theory; someone who can model a plant, close a loop, and then prove it on the bench. This is advanced development: you will evaluate technologies, deliver proof-of-concept prototypes, and build the design libraries and reference architectures that our divisions turn into the products that welders depend on. The technologies and architectures you develop will become the foundation for future Miller welding platforms used by customers around the world. You will work elbow-to-elbow with electrical, software, mechanical, and weld engineers, and partner with division representatives to deliver what they need to delight our customers. Whether you prefer Milwaukee's urban energy or the exceptional quality of life, affordability, and outdoor access of Wisconsin's Fox Valley, you'll find a strong engineering community, room to make an outsized impact, and the freedom to spend less time commuting and more time building great technology. If building the platform behind the product is the kind of challenge that excites you, let's talk. If you're the sort of engineer who can turn theory into hardware and hardware into results, you'll fit right in. You don't need to check every box; if your strengths are rooted in controls, power conversion, and bringing ideas to life, we'd love to hear from you!

Requirements

• Hands-on mastery of multi-kW switch-mode conversion, including hard-switched full-bridge topologies, SiC and other wide-bandgap devices, gate drive, and magnetics.
• Fluency in feedback control, plant modeling, loop compensation, and analog and digital control.
• Implementing control laws on microcontrollers or DSPs with hands-on experience in hardware bring-up, ADC and PWM peripherals, and timing-critical firmware.
• Connecting control, power stage, thermal, EMC, and manufacturability so the whole technology wins, not just the loop.
• Trusting hard measurements over assumptions and proving a design in copper and silicon, not just in simulation.
• Self-directed, customer-focused, eager to learn, and ready to roll up your sleeves when the project calls for it.
• Bachelor's Degree in Electrical Engineering required.
• 5-10+ years of relevant control systems and power electronics experience, or 5+ years for an exceptional engineer who has been a key contributor across many successful designs.
• Demonstrated experience designing and stabilizing digital control loops for switch-mode power conversion.
• Proven multi-kW switch-mode design experience, including SiC or other wide-bandgap devices, full-bridge topologies, gate drive, and magnetics.
• A track record of taking concepts from modeling and simulation through working hardware and measured results.
• Working knowledge of PCB layout for power and mixed-signal designs, with familiarity with design-for-manufacturing and third-party standards such as UL, CSA, and CE.
• A self-starter with strong analytical instincts who thrives in a hands-on R&D environment.

Nice To Haves

• An advanced degree with a controls or power electronics focus is a plus.

Responsibilities

• Architect and model the control systems that define how the next generation of welding engines behave.
• Take new power conversion concepts from control simulation to working proof-of-concept prototypes that show what is possible.
• Create the reference designs that help our divisions reach the market faster and with less risk.
• Prove out emerging power conversion technology and define what it takes to make it robust, manufacturable, and repeatable.
• Partner with division representatives to turn their customer needs into the right technology bets.
• Mentor across the engineering community and raise the bar for control and power electronics design throughout Miller.

Benefits

• 401(k) match PLUS an additional retirement contribution
• 11 paid holidays, 5 sick days, and vacation time
• Company-Paid Insurance – Life, AD&D, Short-Term & Long-Term Disability insurance
• 4 weeks of paid parental leave and adoption reimbursement
• tuition reimbursement
• Relocation support is available for qualified candidates
