## 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.
We don’t care about titles or ticking every box. We care about what you build and the perspective you bring, so if your profile is different, apply anyway.
### **Job Summary:**
This internship is at the core of our operations.
The objective is to take ownership of the **full operational payload workflow** , from mission preparation to client delivery, while contributing to the **continuous improvement of payload systems and data pipelines** based on real operational feedback.
You will be involved in **all operational phases** of an inspection mission : mission planning, remote payload operations, data analysis, and client reporting and will use this hands-on experience to support the **payload and data development roadmap**.
### **The Mission:**
**End-to-End Operational Scope**
Operations Preparation
- Prepare mission parameters and payload configurations
- Test our config to be sure we acquire all data we need
Live Payload Operations
- Operate payloads remotely from the control room during live missions
- Control gimbal and sensors in real time
- Ensure data capture quality (LiDAR and imagery) throughout the mission
Data Analysis & Validation
- Process LiDAR point clouds, imagery, methane sensing
- Analyze collected data to identify defects or points of interest
- Validate data completeness and consistency
Client Delivery
- Prepare structured inspection reports and deliverables
- Ensure data quality meets client and internal standards
**Continuous Improvement & Roadmap Contribution**
- Improve flight preparation methods, payload presets, and operating procedures
- Support Lead Payload and Lead Data on embedded systems and data workflow optimization
- Contribute to tooling, documentation, or automation aligned with the development roadmap
### **Profile Sought:**
**Education:**
Currently enrolled in an **engineering school (4th or 5th year)**, **or** a **final-year Licence / Bachelor** in relevant backgrounds include embedded systems, computer science, mechatronics, robotics, applied physics, aerospace, or similar disciplines.
The following list of skills is exhaustive, while you may not perfectly fit with the profile, we highly value personal growth and development. We see our interns as potential future team leads at HyLight.
