Job Description

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

Role Overview

Mechanical Design Engineer responsible for concept-to-release mechanical design and product realization of battery systems and power electronics for energy and power applications. The role focuses on robust packaging, structural integrity, manufacturable designs, and compliance with electrical safety and environmental requirements, working closely with cross-functional teams through structured design reviews and NPI gateways.

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: Apply GDT (ASME Y14.5) and perform tolerance stack-ups for critical interfaces and sealing features.
- 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 lo
