Design Engineer Intern - Drone Propulsion

AP LUX S.A. is a Luxembourg-based technology startup developing advanced electromechanical systems for drone and next-generation mobility applications. Operating at the intersection of propulsion, aerodynamics, and product innovation, we are building cutting-edge solutions for the future of autonomous aerial systems. 

To support upcoming R&D projects in drone propulsion, we are looking for a highly motivated engineering intern to join our team in Luxembourg and contribute to the development of BLDC motor and propeller systems for light and medium-sized drones. This hands-on internship offers direct involvement in electromechanical design, aerodynamics, prototyping, testing, and real-world product development within a fast-paced and technology-driven environment. 


Key Responsibilities

  • Develop CAD models and support mechanical design iterations  

  • Participate in prototyping, testing, and validation activities  

  • Support the design and optimisation of BLDC motors for drone applications  

  • Contribute to propeller design and aerodynamic optimization (geometry, pitch, efficiency)  

  • Perform basic electromagnetic, mechanical, and aerodynamic calculations  

  • Contribute to simulation activities (motor performance, structural behaviour, airflow)  

  • Analyse test data and propose design improvements  

  • Collaborate with R&D and engineering teams on multidisciplinary topics 

Required Skills and Competencies

  • Passion for engineering and willingness to learn are valued more than prior industry experience 

  • Currently pursuing a bachelor’s or master’s degree in mechanical engineering, Aerospace Engineering, Mechatronics Engineering, or a related field 

  • Solid understanding of engineering fundamentals (mechanics, physics, mathematics) 

  • Interest or basic exposure in one or more of the following areas: 

    • Electric motors / electromechanics (BLDC principles) 

    • Aerodynamics and propeller systems 

    • Structural mechanics and strength of materials 

  • Familiarity with engineering tools such as: 

    • CAD software (e.g. SolidWorks, CATIA, or similar) 

    • MATLAB / Simulink, Python, or equivalent 

  • Strong analytical and problem-solving mindset 

  • Hands-on attitude and willingness to work on real engineering challenges 

Nice to Have

  • Exposure to simulation tools (ANSYS, Motor-CAD, CFD tools such as Fluent or OpenFOAM)  

  • Basic understanding of motor control (e.g. ESC, FOC)  

  • Experience with prototyping or experimental testing  

Personal Attributes

  • Curious, proactive, and eager to learn  

  • Strong attention to detail and engineering rigor  

  • Ability to work on open-ended problems  

  • Good communication skills in an international environment  

What We Offer

  • Direct contribution to real drone propulsion development projects 

  • Hands-on involvement from concept to prototype and testing 

  • Fast-learning environment with high technical exposure 

  • Close collaboration with experienced engineers and founders  

  • Paid internship with competitive compensation  

  • Opportunity to grow into a long-term engineering role 

Practical Information

  • Location: Luxembourg 

  • Internship duration: 6 months 

  • Start date: ASAP / Flexible 

  • University internship agreement preferred
