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
