ZERRO POWER SYSTEMS PTE. LTD. Hiring! Full Time Embedded Systems Engineer in North-east Region (Singapore), Earn up to SGD 5,500 - Ricebowl

Job Summary

Mid-Level Embedded Systems Engineer . In this hands-on role, you will design and develop microcontroller-based electronic systems, from writing firmware to creating simple custom PCBs.

Responsibilities

• Develop and debug firmware in C/Assembly for 8051, Arduino, and STM32 microcontrollers.

• Design simple, reliable application PCBs for microcontroller-based systems.

• Perform schematic entry, component selection, PCB layout, and basic design verification.

• Test and validate hardware + firmware integration.

• Support prototyping, troubleshooting, and minor design iterations.

Required competencies and certifications

• Bachelor’s degree (B.E./B.Tech or equivalent) in Electronics Engineering, Electrical Engineering, Computer Engineering, or a related field.

• 3–5 years of hands-on experience in embedded systems development, specifically with microcontroller-based projects.

• Strong proficiency in Embedded C (and basic Assembly where needed).

• Proven experience programming the following microcontrollers:

  • 8051 family (Keil μVision IDE preferred)

  • Arduino/AVR platform

  • STM32 (STM32CubeIDE, HAL/LL drivers, or STM32CubeMX)

• Experience designing simple application PCBs using common 8051-type or similar microcontrollers:

  • Schematic capture and PCB layout

  • Familiarity with at least one PCB design tool (KiCad, Eagle, Altium Designer, or EasyEDA)

  • Basic understanding of component selection, power supply design, and signal integrity for low-to-medium complexity boards

• Knowledge of common communication protocols (UART, I2C, SPI, etc.) and peripheral interfacing.

• Hands-on debugging skills using tools such as oscilloscopes, logic analyzers, multimeters, and in-circuit debuggers (JTAG/SWD).

• Ability to take a project from concept → schematic → PCB → firmware → testing/prototyping

Preferred competencies and qualifications

• Experience with soldering, prototyping, and board bring-up.

• Familiarity with version control (Git) and basic documentation practices.

• Knowledge of real-time operating systems (RTOS) or bare-metal firmware design.

• Any exposure to industrial, consumer electronics, or IoT projects.
