Purpose of the Role

This role owns the hands-on design, development and delivery of the Over-the-Air (OTA) software update and Remote Diagnostics capabilities within Tata Motors' Connected Vehicle Platform. The engineer builds and integrates the cloud services, vehicle-side interfaces and diagnostic workflows that enable software updates, remote diagnostics, repair diagnostics and fleet health monitoring across the vehicle portfolio.

The person is accountable for end-to-end feature delivery — from campaign design and diagnostic session orchestration through cloud backend implementation, automotive protocol integration, testing and production rollout. They work closely with platform architects, vehicle E/E teams, Tier-1 suppliers and cloud engineers to deliver secure, reliable and scalable OTA and diagnostics services that meet engineering, quality and business targets.

Job Responsibilities :

OTA & Diagnostics Feature Development

- Develop OTA software update workflows (FOTA/SOTA), including campaign creation, targeting, delta packaging, rollout and rollback logic.
- Implement remote and repair diagnostics services covering diagnostic session management, DTC read/clear, ECU identification and health reporting.
- Build cloud-native backend services and APIs on AWS for update orchestration, fleet targeting and diagnostics data handling.
- Integrate SOVD-based diagnostics alongside classic UDS workflows to support next-generation service tooling.
- Develop and maintain campaign management logic, entitlement checks and pre-conditions for safe in-field updates.

Vehicle Integration & Automotive Protocols

- Integrate OTA and diagnostics services with the Telematics Control Unit (TCU) and in-vehicle ECUs over telematics interfaces.
- Implement and debug automotive diagnostic protocols — UDS, DoIP, SOVD, SOME/IP and CAN — across cloud and vehicle boundaries.
- Handle vehicle signal and service modelling, ECU addressing and update-package delivery to target controllers.
- Validate end-to-end update and diagnostic flows on vehicle test benches, HIL setups and pilot fleets.

Security, Reliability & Quality

- Implement secure update delivery using PKI, signing, mTLS and certificate management aligned to UNECE R155/R156 and ISO/SAE 21434.
- Deploy services within CI/CD pipelines, using Infrastructure-as-Code (Terraform/CDK) and container orchestration.
- Establish monitoring,



logging and alerting for update campaigns and diagnostic sessions; drive reliability and rollback safety.
- Define and track feature KPIs — update success rate, campaign latency, diagnostic coverage — and act on regressions.

Collaboration & Process

- Work in an Agile / CI-CD-CT environment; support sprint planning with technical estimates and delivery commitments.
- Collaborate with platform architects, vehicle E/E teams and Tier-1 suppliers to align interfaces and integration timelines.
- Review technical specifications, contribute to design reviews and support resolution of field and SOP issues.
- Document designs, APIs and diagnostic workflows to engineering and ASPICE process standards.

Desired Candidate Profile

- B.E./B.Tech in Electronics, Electrical or Computer Science (Telecommunications / Automobile Engineering secondary).
- M.E./M.Tech or relevant cloud/automotive certifications desirable. AWS certification preferred
- 5–10 years total, with hands-on experience in connected car / vehicle diagnostics product development and delivery.
- Minimum 3 years working on OTA, remote diagnostics or repair diagnostics products.

OTA & Vehicle Diagnostics
