Design & Development Engineer - Interior Trims

This is a Design & Development Engineer role in automotive interior design, working on interior trim parts for global OEM programs. You will design and develop parts such as pillar trims, headliners, door trims, consoles, instrument panel parts, air ducts, vents, grab handles and covers, including modifying existing parts for new vehicle variants. The work covers 3D CAD and 2D drawings for plastic and trim parts, packaging, DMU and virtual build checks, applying supplier DFM feedback and styling changes, updating DFMEA and DVP documents, and releasing changes through PLM. You will also support suppliers through technical discussions, tooling reviews and sample approval, making sure parts meet safety requirements such as head impact and airbag clearance. The ideal candidate has strong CAD skills in CATIA, 3DEXPERIENCE or NX, a good grasp of injection moulding, DFM and GD&T, and experience with the design release process.

Design and development

• Design and develop interior trim parts such as pillar trims, headliners, door trims, consoles, instrument panel parts, air ducts and vents, grab handles and covers.
• Create and modify 3D CAD models, assemblies and 2D drawings for plastic and trim parts, including attachments, clips and fasteners.
• Adapt existing or carry-over parts to new vehicle variants or markets, and update surrounding parts affected by the change.

Packaging and validation support

• Carry out packaging studies, DMU checks and virtual build analysis, including assembly sequence and tool accessibility.
• Check gaps, flushness, clearances and interfaces with adjacent trims, body structure and styling surfaces.
• Make sure interior parts meet safety and regulatory requirements, such as head impact and airbag deployment clearance.

Manufacturing and supplier coordination

• Apply DFM feedback from suppliers and design parts for injection moulding and assembly.
• Incorporate styling and quality changes within agreed review loops.
• Support supplier technical discussions, tooling reviews and sample approval, and follow open issues through to closure.

Documentation and release

• Prepare and update DFMEA, DVP and related design documents.
• Release engineering changes and data through the PLM system, following the OEM’s release process.
• Assess the impact of design changes on neighbouring parts and raise change requests where needed.

• B.E./B.Tech (or equivalent) in Mechanical, Automobile, Automotive or a related field. An M.Tech is a plus.
• 6 to 9 years in automotive interior or plastic part design and development.
• Strong CAD skills in CATIA V5, 3DEXPERIENCE, NX or equivalent, including assemblies, surfacing basics and 2D drawings.
• Understanding of injection moulding, design for manufacturing (DFM), tolerance analysis and GD&T.
• Working knowledge of DMU, packaging and virtual build reviews.
• Experience with DFMEA, DVP and the design release process.
• Familiarity with a PLM system such as Teamcenter or similar.
• Knowledge of interior safety and regulatory requirements, such as head impact and airbag clearance.
• Good communication skills for working with styling, CAE, suppliers and cross-functional engineers.
