Duties & Responsibilities

• Oversee the design and development of high-performance power supplies for welding & plasma

systems, focusing on power conversion (AC/DC, DC/DC, DC/AC). * Design robust and efficient power control circuits, including inverter systems, to deliver stable
current and voltage for welding processes (e.g., arc welding, MIG/MAG, TIG). * Ensure compliance with industry standards and safety requirements for high-power systems.

• Optimize power delivery systems for different welding processes, ensuring reliability, thermal

management, and operational efficiency. * Implement advanced control algorithms (e.g., pulse-width modulation, digital control) to improve
welding performance. * Continuously improve energy efficiency and power factor correction (PFC) to meet evolving
market demands * Lead R&D efforts to explore new technologies in power electronics (e.g., GaN/SiC devices) for the
next generation of welding power supplies. * Drive innovation to reduce the size, weight, and cost of welding power supplies while increasing
performance and durability. * Oversee system-level testing and validation of power electronics designs, ensuring conformance
to performance specifications. * Collaborate with test engineering teams to define validation protocols for thermal performance,
electromagnetic interference (EMI), and reliability. * Manage project timelines, budgets, and resource allocations, ensuring on-time delivery of power
electronics solutions. * Engage with stakeholders (product managers, customers) to understand market needs and align
project goals accordingly. * Ensure designs meet relevant standards and certifications (e.g., CSA, CE) for industrial welding
equipment. * Address power quality, electromagnetic compatibility (EMC), and safety regulations in the
product design process. * Lead and manage a team of power electronics engineers, driving development from concept
through production. * Provide technical guidance and mentorship to the team in the design and optimization of power
systems for welding equipment. * Collaborate with cross-functional teams (mechanical, software, systems engineering) to integrate
power electronics into the final product. * Lead and manage a team of power electronics engineers, driving development from concept
