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-perk 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
