Mechanical Engineer

The position covers all aspects of mechanical engineering: design of parts in metal, plastic, and composite; system sizing and simulation; technical drawings and plans; system assembly and hands-on work; and the setup of test benches to validate mechanical strength.The mission: Working closely with theHead of Mechanics, you will contribute to all mechanical design and improvement efforts for the HyLighter: propulsion system design, light-weighting, and enhancing the robustness of existing components. You will have the opportunity to lead a project from itsinitial concept to full integrationinto the steerable drone. This is a hands-on role whereresourcefulness is key, and you'll have a unique opportunity to learn a lot.Mechanical design iscore to our Tech team, and this role comes withhigh-stakes responsibilities. The team is tackling major developments: new systems, new steerable drones, new ground installations, and many improvements ahead.Personal Note from Josef (CTO):This is a cross-functional, hands-on role that touches all areas of hardware development. You'll have a strong impact on HyLight's growth. We're looking for someone who can quickly take on responsibility toboost the reliabilityof our airship drone and be involved in all new improvement topics. With a team still at a human scale (17 people), this is a unique opportunity to make a big impactProfile SoughtKey Technical Skills:Solid CAD experience (>1 year) using Solidworks, Onshape or Catia, with experience designing lightweight parts for vibration/rotational constraintsStrong hands-on experience in rapid prototyping, 3D printing, CNC, and laser cuttingExperience creating ISO-standard technical drawingsEngineering education with major in mechanical engineeringSupplier management: sourcing and negotiationBroad knowledge of: topological optimization; integration of motors, servos, and control boards; torque and power electronicsExperience managing R&D product development projects, already build real stuff by yourselfDon't have all these skills?
