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
