Johannesburg West: Senior Power Electronics Engineer posted by Network Finance

We are seeking a highly skilled Senior Power Electronics Hardware Engineer to join our growing engineering team. In this role, you will lead the design, development, and validation of advanced power electronics systems and high-reliability hardware. You will be responsible for circuit design, PCB layout oversight, EMC compliance, and driving products from concept to production.
This is an excellent opportunity for an experienced engineer who enjoys solving complex electrical challenges, influencing architecture decisions, and mentoring junior engineers.

Key Responsibilities

• Lead the design and development of power conversion circuits (AC/DC, DC/DC, inverters, motor drives, etc.).
• Own schematic design, component selection, and hardware architecture.
• Drive high-quality PCB layout for power, mixed-signal, and high-density designs (high current, thermal constraints, creepage/clearance requirements).
• Ensure designs meet EMC / EMI compliance requirements; collaborate with test labs and perform pre-compliance testing.
• Support system integration, prototype bring-up, and hardware debugging using oscilloscopes, power analyzers, and other lab equipment.
• Lead root-cause investigations and implement corrective actions.
• Collaborate closely with firmware, mechanical, and manufacturing teams to ensure robust, production-ready designs.
• Mentor junior hardware engineers and review their design work.

Required Skills & Experience

• 5–10 years professional experience in power electronics hardware development.
• BEng degree
• Strong expertise in analog and power circuit design (topologies, magnetics, gate-drive design, thermal considerations).
• Proven experience with PCB layout for power and mixed-signal systems.
• Solid understanding of EMC/EMI design principles and regulatory compliance (EN/IEC/FCC).
• Hands-on experience debugging hardware using lab tools.
• Proficiency with ECAD tools (e.g., Altium Designer, KiCad, OrCAD, Mentor).
• Experience with design for manufacturability (DFM) and reliability engineering.
