Hardware Engineer Intern

🎯 Mission At Vizzia, we design video surveillance units deployed in the field to help secure cities. Around these units, many strategic hardware projects revolve: solar panels, test benches, high-capacity batteries, accessories, consumables, and specific subsystems. Your mission: accelerate the development of these technical building blocks by rapidly transforming ideas into functional prototypes, and then into robust, industrialized systems. You step in where structure, execution, and momentum are needed. From concept to POC. From POC to pre-series. With a strong focus on quality, reliability, and documentation. 🛠️ Responsibilities You will contribute to a full Hardware project (to be defined depending on priorities) - from idea to pre-series. Concretely, this may include: Translating product needs into a functional electronic architecture (component selection, constraints, schematics) Designing production-ready multi-layer schematics and PCBs with zero critical errors Developing structured embedded firmware in C (ESP32, STM32, Arduino-class) Integrating mechanical constraints (form factor, connectors, thermal dissipation) from the design phase Assembling, soldering, debugging, and bringing up prototypes independently Designing test benches Preparing a pre-series (~10 units): BOM stability, supplier files, manufacturability Producing clear and reusable documentation 👉 In short: you can work on everything — from the first schematic to a product ready for replication. ✅ Profile Engineering student specialized in electronics or embedded systems (gap year or final internship) Able to design a complete PCB independently (schematic + layout) Comfortable with embedded C (interrupt handling, I2C, SPI, UART, debugging) Hands-on hardware prototyping experience (Arduino, ESP32, Raspberry Pi, etc.) Understanding of industrialization basics (BOM structuring, DFM, small production runs) Structured, rigorous, capable of root cause analysis Strong learning ability and autonomy Nice to have: Experience in a robotics club DIY 3D printing Benefits 🏡 Hybrid work 🏝 Mandatory internship agreement from your school (1 day off per month) 💻 A Mac or PC depending on your preferences 🍜 60% coverage of meal vouchers worth €9 per worked day 🚃/🚲 Sustainable mobility allowance 💼 Offices located in central Paris (9th arrondissement) ☀️ Annual offsite with the whole team and plenty of company events If you've read this far, you're probably very interested in the role and/or Vizzia. We'd like to hear from you even if you feel ou don't check every box.
