Job description

1. Roles and Responsibilities

• Hardware & Firmware Development: Design, develop, test, and maintain embedded software and firmware using C/C++ for microcontrollers and microprocessors (e.g., STM32, ESP32, PIC, ARM Cortex-M, Raspberry Pi).
• Circuit & Hardware Integration: Collaborate with hardware teams to interface sensors (temperature, accelerometer, gas, light), actuators, analog/digital IOs, and power management modules; assist in schematic reviews and PCB debugging.
• IoT Connectivity & Protocols: Implement and optimize communication protocols for IoT devices, including MQTT, CoAP, HTTP/HTTPS, BLE, Wi‑Fi, LoRaWAN, Zigbee, SPI, I2C, UART, and CAN bus.
• Edge & Cloud Integration: Connect edge IoT devices seamlessly with cloud platforms (AWS IoT Core, Azure IoT Hub, Google Cloud IoT, or custom MQTT brokers); secure telemetry data transmission using TLS/SSL encryption.
• System Testing & Debugging: Perform low-level hardware debugging and firmware testing using logic analyzers, oscilloscopes, multimeters, and JTAG/SWD debuggers; troubleshoot signal integrity, memory leaks, and timing constraints.
• Power & Performance Optimization: Optimize firmware code and power consumption profiles to ensure ultra-low power states, battery longevity, and efficient execution on resource‑constrained embedded systems.
• OTA & Security Implementation: Design and maintain Over-The-Air (OTA) firmware updates and implement device security standards, including secure boot, cryptographic hardware keys, and hardware root of trust.
• Documentation & Compliance: Create comprehensive technical documentation, including system architecture diagrams, API specifications, testing procedures, and support compliance with industry safety and EMC standards.

2. Preferred Candidate Profile

Education:

• Bachelors or Master’s degree in Electronics & Communication Engineering (ECE), Electrical Engineering (EEE), Embedded Systems, Computer Science, or related technical disciplines.

Work Experience:

• 2 to 6+ years of hands‑on experience in embedded firmware design, microcontrollers, and end‑to‑end IoT product deployment.

Technical Skills:

• Proficiency in Embedded C/C++ programming and real‑time operating systems (FreeRTOS or Embedded Linux).
• Strong working knowledge of hardware interfaces (SPI, I2C, UART, ADC) and wireless stacks (Wi‑Fi, BLE, LoRaWAN, Cellular/NB‑IoT).
• Direct experience with cloud IoT platforms (AWS IoT Core, Azure IoT) and data serialization formats (JSON, Protobuf).
• Familiarity with hardware tools (oscilloscope, logic analyzer, solder station) and IDEs (Keil, STM32CubeIDE, ESP-IDF, VS Code).

Soft Skills:

• Strong analytical and hardware‑software co‑debugging skills.
• Good communication and collaboration skills to work across cross‑functional hardware, cloud, and QA teams.
