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.
