Senior Internet of Things Engineer

KEY RESPONSIBILITIES

The current opening is for Embedded Engineer, wherein the member is responsible for designing, developing and maintaining embedded hardware and firmware, ensuring device connectivity and coordinating with production and backend teams for IoT integration.

Roles & Responsibilities :-

1. Design embedded systems from concept to production, including schematics, PCB layout and board bring-up.

2. Develop FreeRTOS-based firmware using FSM architecture for robust and maintainable systems using C/C++.

3. Integrate LTE, GPS, Wi-Fi, BLE as well as other sensors based on communication protocols (UART, SPI, I2C, CAN)

4. Implement OTA updates and system reliability mechanisms.

5. Coordinate with PCB manufacturers and vendors for fabrication, assembly, and component sourcing.

6. Implement device-to-cloud communication using MQTT and JSON-based data formats.

7. Perform field debugging, root-cause analysis and production issue resolution.

8. Collaborate with backend/IoT teams on protocols, APIs and data handling.

9. Maintain comprehensive hardware and firmware documentation.

HARDWARE REQUIREMENTS

1. Hands-on experience with PCB schematic design and layout (upto 4 layers) on KiCad/Orcad, including projects developed for IoT systems.

2. Hands-on design of LDOs, buck/boost regulators and protection circuits.

3. Strong understanding of ESP32 integration and related peripheral interfacing.

4. Hands-on experience integrating LTE (EC200), GPS or similar modules.

5. Experience with USB Type-C implementation and SD card hardware integration.

6. Understanding of antenna placement, impedance matching and basic RF/EMI principles.

7. Practical experience with DSO, CAN tool, logic analyzer and multimeter for debugging.

SOFTWARE REQUIREMENTS

1. Proficient in C/C++ development using ESP32 SDKs (ESP-IDF, PlatformIO) and Arduino framework.

2. Hands-on experience with FreeRTOS, including tasks, mutexes, semaphores and FSM-based firmware design.

3. Require in-depth understanding of CAN and MQTT protocols.

4. Understanding and hands-on experience with Wi-Fi, BLE, UART, SPI, I2C protocols.

5. Hands-on experience using AT commands for LTE, GPS or other peripheral modules.

6. Experience in implementing OTA (Over-the-Air) firmware updates for ESP32 over LTE.

7. Basic understanding of JSON data format for device-to-cloud data exchange.
