Electrical Engineer

Job Responsibilities

• Perform and supervise the testing of new designs, processes, warranty improvements, and cost reductions, including coordinating the activities of technical R&D support personnel.
• Design and develop main power electronics architecture for arc welding machines, including DC-AC inverters, AC-DC rectifiers, DC-DC converters, and magnetic components (transformers, chokes).
• Design, prototype, and test PCB circuits, layouts, and electromagnetic devices required for arc welding equipment and battery management systems using PCB design tools (Altium, PADS and Mentor Graphics) and by conducting FMEA (Failure Mode Effects Analysis) and WCA (Worst-Case Circuit Analysis).
• Implement fault detection, sensing circuitry, thermal runaway protection, shortcircuit protection, and overcharge/discharge safeguards to ensure isolation, EMI/EMC compliance design, and fail-safe/redundancy mechanisms for compliance with functional ISO 26262 and IEC 61508 safety standards.
• Implement real-time control algorithms, PWM (Pulse-Width Modulation) generation techniques, ADC (Analog-to Digital Converter) and DAC (Digital-to-Analog Converter) interfacing and digital communication protocols including CAN (J1939 and I2C) for system communication for hardware development, diagnostics, and firmware validation testing.
• Perform thermal modeling, lifetime prediction, and aging analysis of electronic components and battery systems using simulation tools including Mathcad, MATLAB, and Simulink.
• Perform UL/CE/EMC compliance, functional safety, automated testing, and validate system- level hardware using Python, RSLogix, and LabVIEW. Validate system-level hardware and firmware design through HIL (Hardware-in-the-Loop) testing environmental stress testing, and automated test setups using Python, RS Logix, and LabVIEW.
• Use firmware development software such as C/C++ and Linux-based systems for diagnostics, logging, and remote firmware updates. Develop test specifications for production use.
