We are seeking a versatile and hands-on Electronics & IoT Embedded Engineer to join our R&D team. In this role, you will be responsible for the end-to-end design, prototyping, testing, and deployment of smart embedded hardware, sensor nodes, and automation systems.
You will work on multi-disciplinary hardware systems combining ultra-low-power edge devices, wireless telemetry, real-time sensor/actuator integration, and localized control logic.
Key Responsibilities
Hardware Design & Prototyping:

• Design, simulate, and lay out multi-layer PCBs (schematic capture and PCB layout) for mixed-signal, power management, and microcontroller-based boards.
• Perform hands-on bench assembly, SMD/THT soldering, wire harnessing, and component-level debugging using oscilloscopes, multimeters, and logic analyzers.

Embedded Firmware & Industrial Protocols:

• Develop robust, modular firmware in C/C++ for various microcontrollers (e.g., STM32, ESP32, Nordic nRF, ARM Cortex-M).
• Implement, configure, and debug Modbus (Modbus RTU / Modbus TCP) master/slave communication for industrial interfacing and system integration.
• Develop peripheral drivers and communication buses: I2C, SPI, UART, RS485, ADC/DAC, and PWM.

IoT Communication & Telemetry Protocols:

• Integrate and optimize short- and long-range wireless communication modules (BLE, LoRa / LoRaWAN, Wi-Fi, Cellular / NB-IoT).
• Implement lightweight data transmission protocols (MQTT, HTTP/REST, CoAP, WebSockets) for edge-to-gateway or edge-to-cloud connectivity.

Sensors, Actuators & Control Systems:

• Interface, filter, and calibrate diverse analog and digital sensors (environmental, motion/IMU, electrical power/current, optical, etc.).
• Design driving and switching circuits for actuators (relays, solid-state switches, drivers, analog outputs 0–10V / 4–20mA).
• Implement real-time control algorithms and feedback loops (PID, state logic, event-driven triggers).

Power Optimization & System Reliability:

• Architect and tune circuits and firmware for ultra-low power consumption, battery management, and deep-sleep duty cycling.
• Ensure hardware resilience against noise, voltage spikes, and harsh operating conditions.

Qualifications & Requirements

• Bachelor’s or Master’s degree in Electrical Engineering, Electronics, Embedded Systems, Mechatronics, or Computer Hardware Engineering.
• Minimum 3 years of hands-on industrial or commercial product development experience in electronics and embedded IoT systems.
• Proficiency in ECAD software (Altium Designer, KiCad, or Eagle).
• Strong practical lab skills: precision soldering (SMD packages down to 0603/QFN), rapid board modification, and hardware debugging.

Embedded & Connectivity Skills:

• Strong proficiency in Embedded C/C++.
• Practical experience with Modbus RTU / TCP over RS485/Ethernet.
• Proven experience deploying wireless IoT stacks (LoRaWAN, BLE, Wi-Fi, or Cellular) and communication protocols (MQTT).
• Practical understanding of power profiling and low-power hardware design.
• Strong analytical problem-solving skills and attention to hardware reliability.
• Ability to document schematics, bill of materials (BOM), and firmware architectures cleanly.

Nice-to-Have

• Experience with CAN bus or other industrial fieldbuses.
• Basic 3D CAD modeling (SolidWorks/Fusion 360) for mechanical fit and enclosure prototyping.
• Experience with Design for Manufacturing (DFM) and transition from prototype to small-scale production.
