Embedded Engineer

 
Job Purpose: 
The R&D Embedded Engineer will be responsible for designing, developing, and 
testing embedded control systems for welding and cutting equipment, such as MMA, MIG, TIG 
welders, plasma cutting machines, and inverter-based power electronics equipment. The role 
includes firmware development, hardware interface testing, safety compliance, and supporting 
new product development. 
 
Key Responsibilities: 
 Develop and maintain firmware for welding and plasma cutting machines. 
 Work on microcontrollers (STM32, DSP, PIC, ARM Cortex, etc.). 
 Implement control algorithms for voltage, current, PWM, soft start, and feedback loops. 
 Develop device drivers for displays (LCD/LED/TFT), sensors, and communication modules. 
 Support PCB bring-up, debugging, and parameter tuning. 
 Work with the test team to evaluate arc characteristics. 
 Perform current/voltage waveform analysis for weld quality. 
 Support field trials, reliability testing, and certification. 
 Participate in concept design, prototyping, and pre-production runs. 
 Prepare engineering change notes (ECN) and release firmware versions. 
 Prepare firmware architecture documents, test reports, and release notes. 
 Follow ISO, safety standards (IEC 60974 preferred), and internal SOPs.
