Internship new opennings

  • INTERN1FY25: IoT / AI training model

    Reference: INTRN1FY25

    Type: Internship

    Duration: 5–6 months

    Internship  MSEE / Embedded Systems & Artificial Intelligence


    As part of an ambitious R&D initiative at the intersection of industrial IoT and Artificial Intelligence, we are offering a graduate-level internship opportunity for an MSEE or final-year engineering student.


    The internship focuses on the implementation of an AI engine designed to interpret data from a proprietary embedded system. The AI model will be deployed and executed on a secure private cloud server (e.g., AWS), using a customized Foundation Model (FM) pipeline.


    The intern will contribute to:

    • Modeling and interfacing with a real-world electronic system
    • Structuring and processing data collected from the system for training purposes
    • Training and integrating a Foundation Model on a cloud-based environment
    • Creating a feedback loop between AI-driven interpretation and the physical connected object
    • Evaluating the relevance and accuracy of AI responses in the context of real system behavior

    This project offers a unique opportunity to explore the full implementation stack of an embedded AI engine—from data acquisition and RTOS-based firmware to server-side AI analysis and real-time system feedback.

    Why We Insist on a Strong Electronics Background


    As a company specialized in the design and testing of advanced electronic systems, we place strong emphasis on recruiting interns with solid electronics fundamentals. While this project includes high-level AI, cloud, and software aspects, its success depends on a solid grasp of how real circuits behave, how they are modeled, and how they interact with embedded intelligence.


    We value candidates who demonstrate a firm understanding of:

    • Transistor fundamentals (MOSFETs, BJTs, diodes)
    • Circuit theory (Ohm’s law, impedance, filtering, etc.)
    • Basics of RTL design and FPGA logic
    • Use of laboratory instruments (oscilloscopes, multimeters, signal generators)
    • Exposure to electronic simulation tools (e.g., Spectre, ADS, LTSpice, or equivalent)
    • A strong academic track record (high GPA) in electronics and programming disciplines

    Candidate Profile

    • MSEE/Engineering school post-graduate student (final year). Undergraduate students may be considered with a limited scope
    • Good programming skills (Python, C/C++, etc.)
    • Experience with microcontrollers and solid knowledge of MCU architecture, memory management, operating systems, and communication protocols
    • Mastery of basic electronic circuits
    • Experience with electrical circuit simulation tools
    • Comfortable with physical modeling using CAD tools
    • Very good English communication skills (spoken and written)
    • A strong will to learn and push boundaries
    • Ability to work in structured, project-based environments
    • Familiarity with version control systems (Git) is a plus
    • PCB design experience is a plus
