Hardware Engineering Intern / Working Student

**About Aegiron** Aegiron is building the observability layer for Europe's critical infrastructure. Our software-defined sensor nodes enable operators to anticipate threats, identify vulnerabilities and strengthen their resilience against emerging threats. Backed by premier venture capital funds and angels. **The Role** We are looking for a motivated Hardware Engineering Intern or Working Student to support our core team in building and iterating on physical sensor node prototypes. You will get hands-on experience across the full hardware development cycle — from sourcing components and 3D printing enclosures to testing sensors in real-world conditions. You do not need to be an expert; you need to be eager to learn and comfortable getting your hands dirty. **What You'll Work On** * **Prototyping \& Fabrication:** 3D printing enclosures, assembling sensor nodes, and iterating on mechanical designs based on test results. * **Sensor Testing:** Setting up test rigs, running measurements, and documenting sensor performance (range, FoV, environmental behaviour). * **CAD Support:** Assisting with enclosure and mounting designs in Fusion 360, SolidWorks, or equivalent. * **Component Sourcing:** Researching sensors and electronic components, comparing datasheets, and managing orders from distributors like Mouser and DigiKey. * **Integration Support:** Helping connect sensors to our edge compute platform and troubleshooting hardware-software interfaces alongside the engineering team. **What We're Looking For** * Currently enrolled in a degree in mechanical engineering, electrical engineering, mechatronics, industrial design, or a related field. * Some hands-on experience with 3D printing (FDM or SLA) — personal projects, university labs, or maker spaces all count. * Basic familiarity with a CAD tool (Fusion 360, SolidWorks, Inventor, or similar). * Ability to read a datasheet and understand basic electronics concepts. * Curiosity, initiative, and a bias toward building things rather than just reading about them. **Nice-to-Haves** * Experience with basic electronics (soldering, breadboarding, Arduino/Raspberry Pi). * Exposure to sensor systems (cameras, radar, microphones, LiDAR). * Familiarity with interface protocols (SPI, I²C, UART, USB). * Personal projects or a portfolio that shows you like to make things. **Why Join Aegiron** * **Learn by doing:** Work directly with the founding team on a real product, not a side project that lives in a drawer. * **Ownership from day one:** Your prototypes will ship — not sit in a report. * **Cutting-edge stack:** Get hands-on time with multimodal sensors, NVIDIA Jetson, and edge AI systems. * **Path to full-time:** Outstanding interns will have a direct path to a founding engineering role.
