Job Description

Design, develop, and maintain embedded firmware for air conditioner control systems

(indoor and outdoor units).

? Implement and optimize control algorithms for expansion valve operations.

? Integrate firmware with hardware components such as sensors, motors, and inverter

drives.

? Collaborate with the hardware and mechanical teams for PCB bring-up and system

validation.

? Perform functional, performance, and endurance testing of control boards.

Identify and resolve software/hardware integration issues during prototype and

validation phases.

? Support EMI/EMC testing and implement required firmware countermeasures.

? Fine-tune control parameters to achieve better system efficiency, performance, and

reliability.

? Prepare and maintain design documents, test plans, release notes, and change logs.

? Ensure all development activities comply with company coding standards and quality

processes.

? Work closely with the testing, hardware, and production teams during development and validation.

Proficiency in Embedded C/C++ programming for real-time

applications.

? Strong hands-on experience with 8/16/32-bit microcontrollers

(Renesas, NXP, STMicroelectronics, Microchip, etc.).

? Expertise in communication protocols: UART, SPI, IC, RS485,

Modbus, CAN.

Experience with ADC/DAC, PWM, timers, interrupts, and

watchdog configuration.

? Proficiency with debugging tools (oscilloscope, logic analyzer,

emulator, JTAG).

? Familiarity with firmware version control tools (Git, SVN) and

build environments (Keil, IAR, MPLAB, etc.).

? Exposure to IoT and connectivity technologies such as Wi-Fi,

BLE, and cloud-based monitoring preferred.

? Understanding of PCB schematics, circuit behaviour, and basic

electronic components.

? Knowledge of firmware development lifecycle including

requirement analysis, design, implementation, testing, and

validation.

? Experience with firmware over-the-air (FOTA) updates, power

management, and secure bootloaders is an advantage.
