Mechanical Design Engineer (m/f/d)

Design and develop innovative mechanical systems for advanced unmanned helicopter platforms, focusing on structural performance, reliability, and aerospace engineering excellence.

Your Role & Responsibilities

• Design and develop mechanical systems for unmanned helicopters, including structural components, landing gear, propulsion systems, and control mechanisms

• Contribute to the design and development of composite structures or rotating machinery components such as rotor heads, turbines, and propellers

• Apply expertise in composite materials to optimize weight, strength, and durability of aerospace components

• Perform mechanical analysis and simulations, including hand calculations and simplified finite element analysis (FEA), to evaluate structural integrity and performance

• Support the design and testing of rotating systems while ensuring reliability, vibration control, and mechanical performance

• Conduct dynamic load assessments and fatigue analysis for rotor systems and gas turbine components

• Collaborate with manufacturing and testing teams to build prototypes and execute validation testing activities

• Ensure designs meet performance, safety, and operational requirements through testing and verification processes

• Prepare and maintain engineering documentation including design specifications, testing procedures, and maintenance documentation

• Work closely with electrical, aerodynamic, and software engineering teams to ensure integrated system performance

• Ensure compliance with relevant industry standards, safety regulations, and internal quality requirements

• Contribute to continuous improvement initiatives by applying advancements and best practices in mechanical engineering and UAV technologies

• Support international projects and travel as required

Requirements

Required Technical & Professional Expertise

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related field with a minimum of 3 years of industry experience (Master’s degree with 2+ years considered equivalent)

• Proven experience in mechanical engineering, preferably within the manned helicopter, UAV, or aerospace industry

• Hands-on experience with either composite structures or rotating machinery and mechanical components is required

• Strong understanding of mechanical design principles, materials science, and manufacturing processes

• Proficiency with CAD software, preferably CREO, and mechanical simulation tools

• Knowledge of structural analysis, mechanical simulations, and engineering calculations

• Strong analytical, technical, and problem-solving capabilities

• Excellent communication and interpersonal skills with the ability to collaborate across multidisciplinary teams

• Good English language skills (written and spoken); German is desirable

• Eligibility to work in Switzerland (Swiss or EU citizenship required)
