EE Architecture Vehicle Design Engineer

Upstream EE Architecture

Location: Chennai: Onsite

Job Type: Permanent

Role Overview

Upstream EE Architecture role focused on upstream Electrical & Electronic Architecture definition, vehicle platform architecture, communication network strategy, power architecture, system integration, cybersecurity, functional safety, and scalable Software Defined Vehicle (SDV) architecture.

Key Responsibilities

EE Architecture Definition

• Define the EE architecture master plan:
• Selection of communication networks:
• Automotive Ethernet
• CAN FD
• LIN
• Centralisation of power:
• Transition from a conventional architecture to a zonal architecture
• Centralized architecture around supercomputers

Power Architecture Management

• Manage power distribution, which is crucial in electric vehicles:
• High-voltage architecture (400V / 800V) for traction
• Low-voltage architecture (12V / 48V) for accessories and control units

Architecture Specification & Functional Allocation

• Draft the Architecture Specifications (AS), which will serve as the technical bible for the development teams.
• Break down and assign the vehicle's functions to the appropriate components or control units
• Define the software and physical (inter-system) interfaces to ensure effective communication between the various control units.

Cybersecurity & Functional Safety

• Address cybersecurity from the early design stage.
• Ensure compliance with functional safety standards:
• ISO 26262
• ASIL
• ISO21434

Technology & Architecture Decisions

• Make technology choices at an early stage.
• Assess the cost-benefit ratio between a software update and the addition of a physical component (hardware).
• Perform architecture decision and trade-off analysis.

Physical Architecture & Optimization

• Work on the layout of electronic control units.
• Optimize cable harnesses for weight reduction.
• Support ECU layout and vehicle packaging optimization.

OTA & Scalability

• Ensure scalability:
• Design a scalable EE architecture
• Support OTA (Over-The-Air) remote updates
• Enable lifecycle software updates throughout the vehicle lifecycle

Upstream Activities: Upstream activities happen early in the development cycle, before detailed development and testing begin.

• Purpose is to define what needs to be built and how it should be designed.
• Typical Upstream Activities:
• Requirements Definition
• Architecture Design
• Risk Analysis
• Concept Development
• Planning & Governance
