Assembly, Integration & Testing (AIT) Intern

## About HyLight Power lines, gas pipelines and railways are still inspected the way they were 50 years ago: by helicopter. Expensive, noisy, and up to a tonne of CO₂ per flight hour. We built the alternative. The HyLighter is a 12-metre autonomous airship running on hydrogen. It flies for up to 10 hours, almost silently, and spots a 1 mm defect from 25 metres up. But the airship is only half the story. Every flight brings back massive amounts of LiDAR, imagery and methane data, and that’s where the value is.

Our AI turns it into what operators act on: 50+ types of defects detected automatically, and leaks pinpointed across their network. It’s not a prototype. HyLighters already fly missions for France’s largest energy and rail operators and have flown over the Palace of Versailles. Backed by Y Combinator, we just raised €13M to go from 4 airships to 15. **Working at HyLight** We design, build and fly every HyLighter, and turn its data into insight, all under one roof on a former airbase.

Which means: - **You own it all the way.** At a big aerospace company, you’d own a small piece of one subsystem. Here, you design it, test it, stand on the airfield when it flies, and see the client act on the data it brings back. - **Weeks, not years.** Ideas go from whiteboard to flight test in weeks. - **Responsibility from day one.** The founders’ average age is 27. Nobody here waits for permission. **Job Summary** As we ramp up production to build our next batch of HyLighters, the **Assembly, Integration & Testing (AIT) Intern** is the critical link between design engineering and real-world flight hardware.

Reporting directly to the Head of Production and collaborating closely with our mechanical and embedded systems engineers, you will work hands-on in the HyLight Base. Your core mission is to assemble, wire, integrate, and validate the mechanical, electrical, and avionics subassemblies of our airships, taking them from bare structural components to fully integrated, flight-ready ariship. **Duration:** 4–6 months ### **Key Deliverables & Responsibilities** - **Mechanical & Structural Assembly:** ### **Ideal Profile & Qualifications** **Academic Background:** Currently enrolled in a License, BTS, or BUT degree program in Mechatronics, Mechanical, Electrical, or Aerospace Engineering. - **Practical & Technical

Skills:

** **What We Offer:** - Real responsibility and mentorship. - Potential to become a shareholder in HyLight upon hiring. - 100% reimbursement of public transport pass (Navigo) or €800/year for sustainable commuting. - Bike provided for commuting. - Free lunch. - Bi-annual offsite trips with the whole team. ### **Location** Base 217, Brétigny-sur-Orge, accessible via RER C
