Position: Electrification Reliability Engineer

Domain: Automotive

Job Type: Permanent/Contract

Location: Hybrid – Project Site Bangalore, India.

​

Key Responsibilities:

The Reliability Engineer for Traction Battery Systems is responsible for ensuring robust, durable, and safe performance of high‑voltage battery packs across the full development lifecycle. You will lead structured reliability analysis, define verification strategies, model degradation behaviour, and drive cross‑functional issue resolution. The role requires strong technical depth in battery systems, analytical rigour, and the ability to influence design teams through data‑driven reliability insights.

Design Reliability & Structured Analysis

- Lead and review DFMEA, DRBFM, FMA, and other structured reliability and risk‑assessment activities.
- Ensure reliability requirements, mitigations, and lessons learned are embedded into design releases.
- Provide early‑phase reliability input into system architecture, component selection, and design trade‑offs.

Verification Strategy & DVP Ownership

- Define, set, and maintain Design Verification Plans (DVPs) for battery packs, modules, and sub‑systems.
- Create detailed test procedures, acceptance criteria, and instrumentation strategies for reliability, durability, and abuse testing.
- Monitor reliability target assessment at successive development gateways, ensuring maturity progression and risk closure.

Failure Analysis & Mechanism Identification

- Lead root‑cause investigations for failures observed in CAE, validation, or field operation.




- Identify and model failure mechanisms including thermal, electrical, mechanical, chemical, and ageing‑related degradation pathways.
- Drive corrective actions and design improvements using structured reliability engineering methods.

Reliability Modelling & Prediction

- Develop and maintain reliability models (Weibull analysis, degradation modelling, life prediction, reliability block diagrams).
- Quantify reliability risks and forecast long‑term performance using physics‑of‑failure and data‑driven approaches.
- Support reliability target setting and compliance with internal and regulatory requirements.

Battery Degradation & Lifecycle Analysis

- Lead analysis of battery ageing, including calendar ageing, cycle ageing, SEI growth, impedance rise, and capacity fade.
- Validate degradation models with supplier data, CAE predictions, and physical test results.
- Provide insights to design, thermal, controls, and BMS teams to optimize battery life, warranty performance, and customer usage robustness.

Quality & Current Reliability Projects

- Own reliability deliverables for current production and development programmes.
- Drive cross‑functional quality improvement initiatives,



including field issue reduction, warranty analysis, and reliability KPIs.
- Represent reliability engineering in programme reviews, supplier discussions, and senior management forums.

​

Stakeholder Collaboration

- Work closely with Battery Design, CAE, Thermal, BMS, Safety, Manufacturing, and Supplier Quality teams.
- Act as the primary reliability interface for internal and external stakeholders, ensuring alignment across engineering and programme functions.

​​ ​

Skills, Knowledge & Experience:

​

- Degree or higher in Mechanical, Electrical, Automotive, or Reliability Engineering.
- Robust technical background in traction battery systems, cell chemistry, pack design, and BMS interactions.
- Proven experience in reliability or quality engineering within automotive or high‑reliability industries.
- Deep understanding of DFMEA, DRBFM, FMA, root‑cause analysis, and structured problem‑solving.
- Experience with reliability modelling tools (Weibull++, Reliasoft, Python‑based modelling, etc.).
- Knowledge of battery degradation mechanisms, ageing models, and validation methods.
- Strong analytical skills, attention to detail, and a rigorous approach to data interpretation.
- Excellent communication and presentation skills, able to influence senior stakeholders.
- Proactive, self‑driven, and able to manage multiple technical streams simultaneously.
- Knowledge of System Safety is highly desirable. Safety Standard ISO26262 Experience &/Or Certification
