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.
