Firmware Engineer

Job Summary

The role is responsible for hands-on coding, debugging, hardware coordination, and developing new firmware concepts. You will work closely with the hardware, validation, and production teams to ensure the smooth functioning and reliability of the product.

Key Responsibilities

Firmware Development

Develop firmware in Embedded C for 8/16/32-bit microcontrollers (e.g. PIC, Nuvoton etc..)

Develop & optimize Firmware for GSM/GPRS/IOT Modules.

Implement OTA updates, error handling, power management

Work with cloud platforms (MQTT/HTTP APIs) for IoT data communication

Interface with hardware peripherals: GPIO, ADC, PWM, Timers, UART, I2C, SPI, etc.

Implement communication protocols and control logic

Write modular and well-documented code using best practices

Use version control for firmware

New Concept / Feature Development

Support development of new product features and prototypes

Create proof-of-concept firmware for early-stage idea validation

Collaborate with team during features planning

Suggest improvements based on real-world application needs

Testing & Debugging

Perform unit-level and integration testing of firmware modules

Use tools like oscilloscope, logic analyzer, UART terminals, and IDE debuggers (e.g., MPLAB, Keil)

Assist validation team in real-time testing and application simulation

Identify and resolve firmware bugs and performance issues

Support hardware-firmware integration testing

Hardware Coordination

Understand hardware schematics, pinouts, and datasheets

Work closely with hardware engineers during initial Board power ON

Identify whether an issue is firmware-related or hardware-related

Ensure correct peripheral configurations and timing

Documentation & Release

Create documentation: flowcharts

Maintain firmware version history and release notes

Participate in design reviews and code walkthroughs

Provide firmware loading guides for production/QA teams

Failure Analysis & Support

Support field testing and production debug

Assist in Root Cause Analysis (RCA) of software-related failures

Implement firmware corrections and validate fixes

Provide debug logs, issue reports, and traceability support for CAPA

Skills Required

Technical Skills

Proficient in Embedded C programming
