Gearbox Design Engineer

Job Title

Gearbox Design Engineer

Company Overview

Preet Group is a leading Indian equipment manufacturer, specialised in heavy-duty gearboxes, gear drives and rolling-mill equipment. Their Gear & Gearbox division develops custom gearboxes (worm, parallel shaft, helical, bevel-helical) for steel mills, cement, power, marine, etc.
As part of the team you will design, analyse, validate and support manufacturing of gearbox units to meet high performance, reliability and industrial-service conditions.

Key Responsibilities

• Conceptualise gearbox architectures to meet application requirements (torque, speed ratio, input/output shafts, mounting, service conditions, space constraints).
• Generate 3D CAD models and detailed drawings of gearbox assemblies, including gears, shafts, bearings, housings, seals and lubrication systems.
• Perform gear geometry design (e.g., helix angles, module, face width), strength & rating calculations, bearing life calculations, shaft design, housing strength and lubricant system design.
• Analyse stresses, deflections, thermal behaviour, lubrication, noise & vibration aspects of the gearbox design; perform FEA or other simulation as needed.
• Ensure designs conform to industry standards (gear standards, bearing standards, ISO/AGMA, etc) and internal quality/reliability benchmarks.
• Collaborate with cross-functional teams: manufacturing, quality, procurement (components/gear blanks), test & validation, service & maintenance.
• Support prototype build, testing, commissioning, troubleshooting and validation of gearbox units (including field service support where required).
• Create and maintain drawing packages, BOMs, specification sheets, test reports and design change documentation.
• Review and optimise existing gearbox products for cost, manufacturability, reliability and performance improvements.
• Provide technical support to customers/field team for gearbox issues, modifications, retrofits and upgrades.
• Maintain up-to-date knowledge of gear technology, materials, lubrication systems and manufacturing methods.

Required Qualifications & Experience

• Bachelor’s degree in Mechanical Engineering or equivalent; Master’s preferred for senior roles.
• Extensive years of experience in gearbox or power-transmission product design (in heavy-industrial, mining, steel-mill, marine or large-drive applications) — adjust based on level.
• Strong working knowledge of gear design (spur, helical, bevel, worm), gearbox architecture, bearings, shafts, housings.
• Proficiency in 3D CAD (e.g., SolidWorks, Creo, CATIA) and GA drawings, plus experience with simulation tools / FEA.
• Familiarity with rating calculations for gears/bearings, fatigue life, thermal and lubricant system design.
• Good understanding of manufacturing processes for gears/gearboxes (gear cutting, grinding, heat-treatment, shafts, housings) and cost-/manufacturability trade-offs.
• Strong analytical, problem-solving skills and ability to translate application requirements into robust design solutions.
• Team player with good communication skills, able to interface with manufacturing, procurement and field teams.
• Willingness to travel for prototype testing, field commissioning and troubleshooting (as required).

Preferred Skills

• Experience with large industrial gearbox systems (e.g., rolling mills, cement mills, wind turbines, marine reduction gearboxes).
• Knowledge of gearbox standards (AGMA, ISO), lubrication system design and NVH (noise/vibration) aspects.
• Experience with reverse engineering/upgrades of gearboxes.
• Exposure to manufacturing quality systems (e.g., ISO 9001) and project-based EPC or turnkey equipment design environment.
• Experience in end-to-end product development: from specification, design, manufacturing to commissioning.
