Description

Location: The ePlane Company, IIT Madras Discovery Campus, Chennai – 603103 Experience Level: 2–5 years (hands-on design & development experience) About the Role: We are looking for a highly capable Mechanical Engineer with hands-on experience in CAD and detailed mechanical design to join our electric Powertrain Team. The role involves working on the design, modeling, and integration of propulsion components, with a specialized focus on rotating machinery such as motors, inverters, and gearbox transmissions for advanced aerial mobility platforms and eVTOL aircraft. Key Responsibilities (Mechanical Focus) ● Create and manage 3D CAD models and 2D drawings of powertrain components, with a focus on rotating assemblies (e.g., motor shafts, rotor/stator housings, high-speed gear sets, complex gearbox casings, bearings, and sealing systems). ● Develop gearbox layouts, transmission systems, and perform detailed tolerance stack- up analyses to ensure component interaction and function. ● Apply Geometric Dimensioning and Tolerancing (GD&T) and DFM/DFA principles to ensure robust manufacturability and assembly feasibility. ● Perform load, stress, and deflection calculations for critical rotating parts (e.g., shafts, gears, bearings) to determine safety factors and material requirements. ● Conduct mechanical design activities for electric motor development, including structural design, containment analysis, and support for rotor dynamics analysis. ● Collaborate with electrical and thermal teams for mechanical-electrical-thermal integration, including liquid/oil cooling flow path design within motor/inverter enclosures. ● Provide CAD support for FEA/thermal simulations and iterate designs based on analysis feedback (e.g., vibration, fatigue, and thermal stress). ● Work with suppliers and vendors on prototype manufacturing, precision machining, and assembly of complex powertrain components. ● Participate in design reviews and documentation control for aerospace compliance. ● Support test and validation activities, including prototype assembly, rig testing, and troubleshooting for high-speed rotating systems. Required Skills & Qualifications ● B.E./B.Tech/M.E./M.Tech in Mechanical, Automotive, or Aerospace Engineering. ● 2–5 years of relevant experience in mechanical design, with a strong preference for EV, aerospace, or automotive powertrain. ● Proven relevant work experience in Rotating Machinery/Equipment (e.g., transmissions, compressors, high-speed pumps, or electric motors). ● Strong proficiency in CAD tools (SolidWorks, CATIA, NX, Creo, or equivalent). ● Expert knowledge of gearbox/transmission design, bearing systems selection, and sealing technologies. ● Expertise in GD&T, detailed tolerance analysis, and familiarity with standards (e.g., ISO/AGMA gear standards). ● Demonstrated ability to perform mechanical load, torque, and stress calculations for motor and gearbox components. ● Exposure to thermal management systems (liquid/oil cooling, heat exchangers) specifically for high-power electric components. ● Understanding of manufacturing processes – precision machining, casting, and additive manufacturing. Preferred (Good to Have) ● Experience with high-power electric motor/inverter packaging (200 kW+). ● Exposure to FEA/CAE tools (ANSYS, SimScale, etc.) for structural, thermal, and dynamic analysis. ● Knowledge of aerospace/aviation standards (RTCA DO-160G, DO-254, MIL-STD). ● Hands-on involvement in prototype assembly, balancing, and rig testing of rotating equipment. What We Offer: ● Opportunity to work on cutting-edge eVTOL propulsion technology. ● Dynamic environment at IIT Madras Discovery Campus. ● Competitive compensation with career growth opportunities. ● Exposure to end-to-end design, development, testing, and certification workflows in aerospace mobility.
