* Perform gear train design and optimization (helical, spur, bevel) including: o Gear ratios, torque transmission, efficiency o Noise, vibration, and harshness (NVH) o Fatigue life and reliability calculations * Design gearbox housings, shafts, bearings, seals, lubrication systems, and mounting interfaces.
* Ensure compliance with railway operational duty cycles, shock loads, thermal expansion, and environmental conditions. 2. Materials Engineering (Critical Focus)
* Select appropriate materials for gears, shafts, housings, bearings, and fasteners, based on: o Fatigue strength o Wear resistance o Toughness o Corrosion resistance o Thermal performance
* Define heat treatment processes, such as: o Carburizing, nitriding, induction hardening o Quenching and tempering processes for gears and shafts * Evaluate and recommend advanced materials and surface treatments, including: o Alloy steels (e.g., CrMo, NiCrMo, etc) o Cast irons and cast steels o Aluminium alloys (where applicable) o Coatings (shot peening, DLC, anti-scuffing, corrosion protection, etc)
* Collaborate with materials and metallurgical teams on failure analysis and root cause investigations. 3. Manufacturing Processes & DFM/DFA
* Ensure Design for Manufacturing (DFM) and Design for Assembly (DFA) principles are applied throughout development.
* Define and validate manufacturing routes for gearbox components, including: o Forging, casting, machining, grinding o Gear cutting (hobbing, shaping, grinding, etc) o Heat treatment and distortion control
* Work closely with suppliers and manufacturing plants to: o Review manufacturability risks o Optimize cost and lead times o Resolve production quality issues * Support process validation, pilot builds, and series production ramp-up. 4. Engineering Analysis & Validation * Perform or guide strength, fatigue, and thermal calculations for gearbox systems. * Use or review FEA and analytical methods to validate design of gearbox components, Gears, Housings, Shafts, Bearings, etc. * Define test plans for type testing, endurance testing, and validation per railway standards. * Analyse test results and implement design improvements. 5. Standards, Compliance & Safety * Ensure designs comply with applicable international and regional railway standards, such as: EN, IEC, ISO; UIC; AAR * Apply RAMS (Reliability, Availability, Maintainability, Safety) principles. * Ensure gearbox designs meet life-cycle requirements (typically 30-40 years). 6. Cross-Functional Collaboration * Collaborate with: o Vehicle integration teams (bogie, traction motor, suspension) o Manufacturing and supply chain o Quality, testing, and validation teams * Provide technical guidance to junior engineers and designers. * Support customer discussions, technical clarifications, and design reviews. Key Skills & Competencies * Deep knowledge of: o Gear design theory and calculations o Failure modes (pitting, scuffing, tooth breakage) o Bearings and lubrication systems * Strong understanding of: o Metallurgy and heat treatment o Manufacturing tolerances and distortions o CAD expertise (any of the following): CATIA, Creo, NX, or SolidWorks * Familiarity with FEA tools (ANSYS, Abaqus, or equivalent) * GD&T and technical drawing standards * Strong analytical and problem-solving skills * Ability to take technical ownership of complex systems * Effective communication with cross-functional and international teams * Mentoring mindset and technical leadership orientation Added Advantage Skills & Competencies * Experience with noise and vibration reduction techniques. * Knowledge of condition monitoring and predictive maintenance concepts. * Exposure to cost engineering and value optimization. * Prior experience with metro, high-speed rail, or heavy haul locomotives. Key Interface * Internal Engineering Teams (Bogie, Traction, Validation) * Manufacturing & Supply Chain * Quality and Reliability Engineering * External Suppliers and Partners * Customers / Certification Bodies. Required Qualifications * Bachelor's degree in Mechanical Engineering, Production Engineering, or Materials Engineering * Master's degree is preferred * 10+ years of experience in railway gearbox or heavy drivetrain design * Proven experience with materials selection and manufacturing process definition * Experience working with global railway OEMs or Tier-1 suppliers is highly desirable.
