Embedded Systems Engineer

Job Title: Embedded Systems Engineer (IoT & R&D)

Role Overview

We are seeking a highly skilled Embedded Systems Engineer with strong hands-on experience in IoT hardware, embedded firmware, networking, cloud integration, security, and power electronics.

The candidate will work end-to-end, owning the product lifecycle—from circuit design and firmware development to secure cloud connectivity and power-stage design.

Key Responsibilities

Hardware & Embedded Systems

• Design, develop, and debug embedded systems using ESP32, Arduino, STM32, Raspberry Pi, and similar platforms
• Interface and integrate sensors, actuators, relays, motors, displays, and industrial I/O
• Perform schematic design, component selection, and PCB design review
• Hands-on hardware debugging using oscilloscopes, logic analyzers, and multimeters

Firmware / Software Development

• Develop embedded firmware using C, C++, Python, or MicroPython
• Implement bare-metal and RTOS-based systems (FreeRTOS / Zephyr preferred)
• Develop and maintain device drivers for sensors, communication modules, and peripherals
• Perform power optimization, memory management, and performance tuning

Networking & Communication Protocols

• Implement and debug connectivity technologies:
• Wi-Fi, Bluetooth, BLE, Zigbee, LoRa, NB-IoT, Cellular (4G/5G)
• Application-layer protocols:
• MQTT, CoAP, HTTP/HTTPS
• Low-level communication protocols:
• I²C, SPI, UART
• Strong understanding of TCP/IP stack and network debugging

Cloud & Backend Integration

• Integrate devices with cloud platforms:
• AWS IoT, Azure IoT, Google Cloud IoT
• Implement REST APIs and WebSocket communication
• Handle telemetry, data ingestion, storage, and basic analytics
• Enable remote diagnostics, monitoring, and fleet management

Security & Reliability

• Implement device authentication and encryption (TLS, certificates, key management)
• Design and deploy secure OTA (Over-The-Air) firmware updates
• Apply IoT security best practices:
• Secure boot, flash encryption, secure key storage
• Design for high reliability, fault tolerance, watchdogs, and recovery mechanisms
