Mechanical Engineering Internship
About the role
Mechanical Integration and Test Intern role at HyLight, focused on bridging mechanical design with operational flight readiness for HyLighter autonomous airships.
Responsibilities
- Creative Design: Contribute to the conceptual design of new mechanical subsystems and airframe evolutions. Transform ideas and prototypes into functional products through rapid iteration (CAD, 3D printing, machining).
- Reliability & Lifecycle Management: Support fatigue models and design accelerated life tests (HALT/HASS) to predict End of Life and maximize fleet availability. Improve drone design for reliable operation in challenging conditions.
- Root Cause Excellence: Support the implementation of Root Cause Analysis processes for field failures, ensuring rapid design updates and a strong feedback loop between engineering and operations.
Qualifications
- Final-year Master's degree (or equivalent) in Mechanical Engineering, Aerospace Engineering, Materials Engineering, Product Design Engineering, or related field.
- Previous internship(s), academic projects, research experience, or hands-on work involving mechanical design, prototyping, testing, manufacturing, or mechanical integration.
- Experience with mechanical systems, aerospace structures, robotics, drones, automotive, or other complex physical systems.
- Willingness to alternate between design and hands-on work; strong shop floor mindset.

About HyLight
Small unmanned hydrogen airships for long range monitoring
HyLight builds and operates autonomous airships for long range monitoring. We focus on detecting methane leaks on pipelines and defects on power lines. Our innovation, the HyLighter, is a crossover between drone and airship technology. Like a drone, it is easily controllable and transportable. And, like an airship, it is extremely energy-efficient, enabling it to fly for up to 10 hours at slow speed (22mph) for optimal data collection which represents a range of 220miles. Today, energy infrastructure operators struggle with conducting inspections that are simultaneously: massive and precise. HyLight offers a solution to precisely detect issues on the infrastructure at an industrial scale, and all of this without emitting GHGs. We are 3 co-founders experienced in hardware and energy companies with Masters in Mechanical Engineering, Computer Science and Business from the best Engineering and Business School in France. We have developed 5 different flying aircrafts and signed 5 pilots programs with major energy infrastructure operators. We also have LOIs worth over $3.5M.
