Mechanical Transmission & Rotary Coupling Engineer

We're Hiring: Mechanical Transmission & Rotary Coupling Engineer Full-Time | Core Team LAT Aerospace | STOL Aircraft At LAT Aerospace, we’re building a clean-sheet Short Take-off and Landing (STOL) aircraft to transform regional air mobility in India. We’re looking for a Mechanical Transmission & Rotary Coupling Engineer to design, analyse, and validate the mechanical power transmission system between the engine and generator – from precision couplings to lightweight gearboxes, optimized for aircraft environments. What you’ll do - Design shaft couplings, torque-transfer interfaces, and rotary joints for engine–generator mechanical integration. - Develop gearbox concepts to match the different RPM and torque requirements of the engine and generator. - Perform structural, fatigue, modal, and dynamic FEA for rotating machinery. - Define tolerances, alignment strategy, bearing selection, lubrication paths, and balancing requirements. - Support prototype fabrication, build test rigs, and perform hardware validation. - Work with engine, generator, motor, and structural teams to ensure seamless system-level integration. - Optimise all transmission components for aerospace constraints such as weight, vibration limits, and reliability. - Maintain detailed drawings, technical documentation, DFM notes, and test reports. What we're looking for - 3+ years of experience in mechanical transmission, drivetrain systems, or rotating machinery design. - Strong understanding of gear trains, torsional dynamics, vibration analysis, fatigue, and high-speed rotation. - Proficiency in ANSYS for advanced structural, modal, fatigue, and thermal FEA. - Familiarity with precision manufacturing, GD&T, tolerance stack-up, shaft machining, and DFM practices. - Experience integrating couplings or gearboxes with engines, motors, or generators. - Bonus: exposure to aerospace lightweighting, high-speed couplings, or UAV drivetrain systems. Why LAT? - Core team opportunity at a high-conviction deep-tech startup. - Real aircraft, real flying hardware, real impact. - Build the future of sustainable aviation in India.
