Job description

Role & responsibilities

• Support board bring-up of prototype PCBs power-up sequencing, rail voltage and current-draw verification.
• Execute functional, circuit-level and performance tests as per ATP under the senior engineers guidance.
• Flash firmware and perform integrated hardware + firmware testing (ST-Link, STM32CubeProgrammer, MPLAB IPE).
• Debug at component level using schematics; verify I2C, SPI, UART, RS232, RS485, CAN and USB on DSO / logic analyzer.
• Bring up and test Linux-based boards serial console, boot log and dmesg analysis, peripheral checks from userspace.
• SMD and through-hole soldering, desoldering and rework on prototype and returned boards.
• Assist in RCA and PCB failure analysis; log defects with clear repro steps and measured data.
• Prepare test reports, test cases, SOPs and checklists; maintain instrument calibration records and ESD discipline.

Must-Have Skills

• Hardware schematic reading, analog & digital fundamentals, LDO / buck / boost regulators, power sequencing, component-level fault isolation.
• Instruments DSO, multimeter, LCR meter, programmable power supply, function generator; thermal imager exposure.
• Protocols I2C, SPI, UART, RS232, RS485, CAN, USB at signal level.
• Linux comfortable on the Linux command line serial console, U-Boot and kernel boot logs, dmesg, image flashing (eMMC / SD), device nodes, i2c-tools, GPIO, can-utils, USB and Ethernet checks; basic shell scripting.
• Controllers STM32 / PIC microcontrollers and ARM Linux boards (i.MX6 or similar).
• Rework SMD (0402 and above) and through-hole soldering.
• Documentation — test reports and test cases in MS Word / Excel; clear written English.
