Mechanical Design Engineer - E+ES (Battery and Power Systems) Role Overview

Key Responsibilities

Concept Development & Engineering Solutions:

- Develop and compare concepts (architecture, packaging, mounting strategy, service access) and translate requirements into feasible engineering solutions.
- Generate layout options and trade studies (mass, cost, manufacturability, serviceability, thermal paths, sealing/IP, safety).
- Drive design decisions with explicit rationale, assumptions, and risk/mitigation plans.

Mechanical Design & Packaging:

- Create 3D CAD models for sheet metal, castings, extrusions, brackets, enclosures, and interfaces supporting batteries and power electronics.
- Develop 3D packaging layouts considering space claim, clearances, creep/clearance for HV, assembly sequence, and serviceability.
- Integrate cooling hardware (coolant pipes/plates), HV-LV harness routing provisions, protection features, and auxiliary components within the mechanical package.
- Select materials and isolations considering strength, thermal performance, electrical insulation interfaces, corrosion (including galvanic), and environmental exposure.

Design Definition, Controls & Release:

- Develop and maintain BOMs, part numbers, and design releases using Teamcenter PLM.
- Define interface control documents (ICDs) and support configuration management across development phases.

Design Verification and support:

- Define load cases and boundary conditions for defined operating, handling,



transport, and mounting scenarios.
- Perform medium to high fidelity simulations to support design decisions.
- Support test planning, instrumentation correlation (strain/vibration/thermal), and issue resolution based on test findings.
- Support resolving field issues by proposing and validating ICA and PCA

Manufacturing & Build Support:

- Implement DFM/DFA and process selection (sheet metal forming, welding, casting, molding) to ensure manufacturability and assembly robustness.
- Address variation, distortion, residual stress, and dimensional control with suppliers and internal manufacturing teams.
- Support DV/PV builds, prototype iterations, and lessons-learned incorporation into subsequent releases.

Design Reviews, Quality & Risk Management:

- Plan and execute structured design reviews (Concept/Architecture, Preliminary Design Review, Critical Design Review, drawing/design release reviews) with clear action tracking.
- Execute DFMEA/PFMEA and drive risk mitigation, validation evidence, and closure of open items.
- Drive APQP deliverables and support PPAP documentation as required.

Supplier Technical Engagement:

- Evaluate supplier capability for fabrication, welding, dimensional control, and quality; validate tooling and process capability.
- Lead technical discussions, drawing clarifications, and issue resolution to meet cost, quality, and schedule targets.

Required Qualifications :

- Bachelor’s/Master’s in Mechanical/Aerospace Engineering or similar.
- Proficiency with 3D CAD and drawing practices; experience with Teamcenter PLM for product data management and release processes.
- Working knowledge of HV packaging constraints (clearance/creepage), sealing/IP, and integration of thermal and harness routing provisions.

Additional Information: This job required 5days working from office.
