Senior Power Electronics Engineer

Location: Niles, ILOur client is seeking a Senior Power Electronics Engineer to play a pivotal role in expanding an in-house power electronics design capability within a sophisticated product engineering organization. This is an opportunity for an experienced LED driver designer to own meaningful circuit development work, influence future product platforms, and become a go-to technical resource for a broad range of power conversion challenges. The engineer will combine hands-on design with supplier collaboration, product improvement, troubleshooting, and technical mentorship, while working in an environment that offers substantial engineering ownership and exposure to varied technologies. This Role Offers: Broad technical exposure across power conversion architectures, dimming and control technologies, battery-powered products, and varied electronic form factors. Potential long-term advancement into engineering leadership. Flexible daily start and end times within a fully onsite work environment. Competitive compensation, plus a target bonus. Comprehensive benefits, including heavily employer-subsidized medical coverage, dental and vision options, retirement benefits, and paid time off. Focus: Personally design and develop LED driver circuitry for new products, taking concepts through detailed power electronics development, prototyping, testing, and refinement. Engineer switch-mode power conversion solutions using architectures such as Buck, Boost, Flyback, and LLC, selecting approaches based on application-specific electrical and performance requirements. Solve practical circuit challenges involving EMI, thermal behavior, component performance, dimming behavior, efficiency, reliability, and manufacturability. Partner with external engineering and manufacturing resources when a product calls for co-development rather than a fully internal design. Evaluate and improve existing power electronics designs to strengthen performance, reliability, functionality, and cost effectiveness. Conduct bench-level troubleshooting and failure analysis using oscilloscopes, electronic loads, power measurement equipment, and other laboratory instrumentation. Support qualification and validation activities for power supplies, control electronics, and related components against applicable performance and safety requirements. Serve as a senior technical resource who shares design knowledge, guides less-experienced engineers, and helps strengthen the team's overall power electronics expertise. Skill Set: Demonstrated recent experience personally designing LED drivers at the circuit level. Experience limited to selecting, integrating, testing, or qualifying commercially available drivers is not sufficient for this position. Approximately 3 to 5 or more years of strong hands-on LED driver or closely aligned power supply design experience, ideally including meaningful design work within the past five years. Deep practical knowledge of switch-mode power electronics, including Buck, Boost, Flyback, and LLC architectures, with the ability to explain design tradeoffs and solutions encountered in real hardware. Strong understanding of EMI mitigation, power supply reliability, qualification, circuit debugging, and root cause analysis. Experience using circuit simulation tools such as PSpice or LTspice to support design decisions and troubleshooting. Familiarity with lighting dimming or control technologies such as phase-cut, 0-10V, DALI, or DMX is valuable, but specialized experience with every protocol is not required. Technical degree preferred, particularly in Electrical Engineering, although substantial current LED driver design expertise is more important than a specific degree path. Self-directed senior-level engineer who can own technical work independently, communicate effectively with internal and external partners, and help develop the capabilities of other engineers.
