IoT Firmware Intern

Job Description - IoT Firmware Intern


Role Summary

We are looking for a resourceful and self-driven intern to join our firmware team working on IoT gateway products. This role is ideal for students who have a foundation in embedded systems and industrial automation, and who are eager to bridge embedded firmware with PLC-based industrial control systems.


Our team currently has strong embedded firmware expertise but limited hands-on experience with PLC systems and industrial interfaces. This internship is designed to explore, prototype, and document how modern PLC systems integrate with IoT gateways, helping us close that knowledge gap.

Main Tasks

Embedded Firmware Development



  • Assist in developing and maintaining embedded firmware in C for IoT gateway products

  • Work with microcontrollers, peripherals, and communication interfaces (UART, SPI, I²C, Ethernet)

  • Support debugging, testing, and validation of firmware features


PLC & Industrial Automation Exploration



  • Research PLC fundamentals, architectures, and programming models

  • Explore common PLC programming standards (e.g., IEC 61131-3)

  • Investigate PLC-to-IoT gateway integration methods, such as:

    • Modbus (RTU/TCP)

    • OPC UA

    • Industrial Ethernet protocols (basic understanding)




Prototyping & Integration



  • Build simple proof-of-concept integrations between PLCs and embedded systems

  • Develop small demo applications (e.g., PLC data ingestion → IoT gateway → cloud)

  • Test interoperability with real or simulated PLC environments


Research & Knowledge Transfer



  • Independently explore industry practices, tools, and architectures

  • Evaluate different PLC vendors, tools, and ecosystem approaches

  • Document findings clearly for the firmware team (technical notes, diagrams, demos)

Experience



Required Qualification





  • Currently pursuing a Bachelor’s or Master’s degree in:

    • Electrical / Electronics Engineering

    • Computer Engineering

    • Mechatronics

    • Industrial Automation

    • Embedded Systems (or related fields)



  • Programming foundation in C

  • Basic understanding of embedded systems concepts:

    • Microcontrollers

    • Memory, interrupts, peripherals



  • Academic exposure to industrial automation or control systems






Nice to have skills





  • Hands-on experience or coursework in PLC programming

    • Ladder Logic (LD)

    • Structured Text (ST)

    • Function Block Diagram (FBD)



  • Basic knowledge of industrial communication protocols
