Senior Firmware Engineer (IoT Solutions) - Geylang

Responsibilities

• Design, develop, and optimize embedded firmware in C/C++ for microcontrollers and SoCs.
• Implement and maintain drivers for various peripheral components (e.g., sensors, actuators, radios).
• Integrate hardware interfaces including SPI, UART, I2C, GPIO, PWM, and ADC.
• Work within embedded frameworks such as Zephyr RTOS, FreeRTOS, andTensorFlow Lite Micro.
• Conduct unit, integration, and system-level testing to validate embedded software performance and stability.

• Collaborate in system architecture design for embedded solutions to meet functional requirements.
• Review and contribute to schematic designs for embedded subsystems; troubleshoot based on circuit diagrams and datasheets.
• Support debugging of hardware-firmware interactions using tools such as oscilloscopes, logic analyzers, and debuggers (e.g., JTAG/SWD).

• Support rapid prototyping and iteration of IoT devices with in-lab fabrication tools.
• Validate hardware designs by running firmware integration tests in early development cycles.

• Collaborate with cross-functional teams including cloud/backend, mobile app, and hardware design engineers.
• Document firmware architecture, configuration settings, communication protocols, and deployment processes.
• Mentor junior engineers and contribute to improving team development standards and workflows.

Requirements

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Embedded Systems, or a related field.

• Hands-on experience in embedded firmware development.
• Strong programming proficiency in C/C++ for resource-constrained environments such as microcontrollers.
• Demonstrated experience with hardware interfaces and embedded communication protocols.
• Hands-on experience with firmware debugging and testing tools (e.g., GDB, serial consoles, logic analyzers).
• Experience using schematic diagrams to identify signal paths, interface connections, and potential hardware faults during embedded development.

• Excellent problem-solving skills with a strong attention to detail.
• Ability to work independently as well as collaboratively in a fast-paced environment.
• Strong verbal and written communication skills, with the ability to document and present technical information clearly.

• Experience with RTOS, low-power system design, and wireless communication stacks (BLE, Wi-Fi, LoRaWAN, etc.).
• Comfortable with end-to-end PCB development — from schematic to fabrication and bench testing.
• Exposure to edge ML, MQTT/CoAP protocols, or cloud integrations (AWS IoT, Azure IoT Hub, etc.).
