Autonomous Drones Engineer Internship

About HyLight:

HyLight’s mission is to help society become more resilient to climate change by improving the observation and inspection of infrastructure.

We build HyLighters, airships that collect data across vast distances with zero emissions.

Our activities include:

• Detecting methane leaks from gas infrastructures (4% of global GHG emissions)

• Inspecting power lines to prevent outages and wildfires

By 2030, we aim to become the global leader in aerial monitoring.

In just 3 years, we have pushed the realm of possibilities as we have:

• Developed 8 iterations of the HyLighter

• Logged over 300 flight hours

• Secured our first inspection contracts with Europe’s largest infrastructure operators

• Joined the world’s top startup accelerator, Y Combinator

• Raised €6 million

HyLight is aiming for a diverse and included team. If your profile doesn't fit all the description but you can bring a diverse point of view, push it forward, it will be highly appreciated.

We’re well-funded and backed by top investors, providing the resources you wish you had when building your own business. We don’t care about traditional roles or titles—just that you’re smart, proactive, and bring the same founder-level ownership and drive to help us build something massive.

Job Summary:

This internship encompasses all subjects related to the Guidance, Navigation, and Control of our autonomous airship, the HyLighter. GNC is paramount to guaranteeing the perfect execution of our flights. Your mission is to contribute to enabling HyLight to operate pilotless airships in diverse conditions while proving their robustness to regulatory authorities. This is a high-impact internship that will involve close collaboration with the entire Technical and Regulatory teams.

A Note from Amine (GNC Lead)

"We have a massive challenge ahead of us: building from scratch the reliable control systems for a completely new type of aircraft, an airship. This role requires a rare balance. You need the analytical, mathematical, and scientific depth to develop complex control laws and implement them in code, alongside a natural intuition for flight dynamics and aerodynamics. At the same time, you must remain incredibly pragmatic, with the ability to be on the ground, testing rapidly, and debugging driver or electronic issues in the field."

The Mission:

Under the guidance of our CTO and in collaboration with the GNC and Embedded teams, your responsibilities will include:

• Modeling & Control: Understand and model airship dynamics to design and implement control and guidance laws for mission execution.

• Robustness & Safety: Contribute to the development of flight strategies for difficult conditions and design risk mitigation strategies for degraded modes.

• Hardware Integration: Debug embedded systems and implement flight computers, actuators, and various types of sensors.

• Testing & Documentation: Define and participate in flight tests and simulations, ensuring thorough documentation of implemented models and control laws.

• Future Innovation: Improve the performance of existing airships while actively participating in the design of future flight solutions.

Profile Sought:

Education: Final-year Master's degree (or equivalent) in Aerospace, Mechanical, or Electrical Engineering.

Experience: Previous internship(s), research experience, academic projects, or hands-on work in Guidance, Navigation & Control, Flight Dynamics, Robotics, Aerospace, Automotive, or Autonomous Systems.

Background: You have worked on GNC, Flight Dynamics, or Control Systems through internships, university projects, research, student teams, or personal initiatives. Experience with drones or autonomous vehicles is a strong plus.

The following list of skills is exhaustive. While you may not perfectly fit the profile, we highly value personal growth and development. We see our interns as potential future team leads at HyLight.

Technical Skills:

This is an exhaustive list of sought-after skills. While you may not have experience in all of them, we're looking for strong fundamentals, curiosity, and a willingness to learn.

• Systems Mastery: Knowledge of modeling and control with exposure to Simulink and solid theoretical foundations in dynamics and automation.

• Programming: Good skills in Python and C/C++, with experience using MATLAB/Simulink through coursework, research, or personal projects.

• Embedded Software: Understanding of microcontrollers, actuators, drivers, and embedded software concepts, with hands-on experience through academic or personal projects.

• Tools (Plus): Knowledge of PX4, MAVLINK, and QGroundControl (QGC) is a significant advantage.

• Data Analysis: Able to extract insights from simulation or flight data.

Soft Skills:

• Entrepreneurial Mindset: Methodical but enterprising, with strong curiosity, self-motivation, and the ability to learn quickly.

• Project Management: Ability to organize your work, manage priorities, and independently drive assigned tasks.

• Communication: Excellent interpersonal skills to interact effectively with internal staff and external partners.

• Enjoys hands-on work (prototyping, setup, field testing).

Languages:

• English (fluent – internal communication and documentation)

What We Offer:

• 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

• Excellent work environment: international team, team events, beautiful offices on a former airbase

Why You Should Join:

• Founder Mentality: We value extreme ownership and want people who think like founders—fast decision makers, natural problem solvers, and executers.

• Ground Floor Opportunity: You’ll be helping to shape and grow a revolutionary company with the resources to back it.

• Impact & Speed: Work in a fast-paced environment where your contributions will have immediate, tangible effects on the company’s success.

Interview Process:

• Introductory phone call (20 min)

• A 1-hour technical case study followed by a debrief with team members

• On-site meeting with the team (1h)

Location:

Office: Base 217, Brétigny-sur-Orge, accessible via RER C.

• Lab and Warehouse access

You’ll work side-by-side with experts in embedded, aerospace, and hydrogen propulsion systems—where your impact matters from day one
