Job description

LTTS India

Job Description

The Mechanical Design Engineer - Shafts, Bearings, Sumps & Oil Systems is responsible for the mechanical design, integration, and lifecycle development of rotating support and lubrication systems within gas turbine propulsion architectures. This includes bearing chambers, sump structures, oil feed/scavenge lines, sealing interfaces, and associated thermal and structural design considerations.

Key Responsibilities

• Mechanical design of bearing compartments, sump housings, oil nozzles, scavenge features, and support structures for rotating shafts and modules.
• Develop and manage 3D CAD models and 2D detailed drawings of:
• Oil feed and scavenge systems (tubes, fittings, manifolds)
• Bearing supports and retention systems
• Sump pressurization and ventilation elements
• Design and integrate dynamic sealing systems (labyrinth, brush, carbon face seals) between sump chambers and core flow paths.
• Implement Design for Manufacturability (DFM) across forged, cast, and machined housings and plumbing assemblies.
• Define tolerances, interfaces, and joining techniques for complex assemblies.
• Participate in engine build, test preparation, and integration reviews.

Qualifications & Experience

• Aerospace, Mechanical Engineering degree or a related field.
• Strong background in gas turbine propulsion, mechanical design, integrity and heat transfer.
• Fluent in English
• Experience: 5-15 years or more.
• Experience in one or a combination of the activities, not limited to
• Design of gas turbine externals and accessories i.e., fuel pump, oil pump, bleed lines.
• Design and sizing of disks, shafts, couplings, connection elements.
• Design and sizing of accessory gearbox, shaft power off-take
• FRACAS (Failure Reporting, Analysis, & Corrective Action System) activities.

Skills

• Technical skills in one or a combination of stated topics.
• Proficient in one of design packages such as Solidworks, Siemens NX or similar.
• Experience in PLM tools such as Teamcenter, Windchill or similar.
• Experience in FEA, or lower order simulation methods.
• Experience in programming using C, Matlab/Simulink or similar.
• Awareness on the state-of-the-art technologies in materials, aerodynamics, and structural mechanics to link with mechanical design for gas turbine propulsion
• Good communication and presentation skills to interact with team members, clients, and vendors.
• Ability to solve problems, prioritize tasks and delegate when necessary
