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
