About the role
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.
