Job Title:Sr. Engineer BESS Battery Pack Design, Testing & Validation

Location: Bangalore

Job Type: Full time

Experience:3+ years preferred

About the Role:

We are hiring a Senior Engineer with in-depth expertise in the design, testing, and validation of battery packs for Battery Energy Storage Systems (BESS). This role will be responsible for developing protected, reliable, and high-performance lithium-ion battery pack systems—from cell selection and mechanical/electrical design to testing, validation,

and compliance.

The ideal candidate will work cross-functionally with R&D;, manufacturing, and QA/QC teams to deliver battery pack solutions that meet performance, safety, thermal, and regulatory standards for grid-scale, commercial and industrial applications.

Key Responsibilities:
Design battery pack architecture (cell-to-module, module-to-pack)

including mechanical layout, electrical schematics, and thermal systems.
Select appropriate cells (LFP, NMC, etc.) based on application-specific

performance and safety criteria.
Integrate and validate Battery Management Systems (BMS), thermal

protection, contactors, and fuse logic.
Collaborate with mechanical design teams on enclosures, structural

integrity, and thermal management.




Define and execute DFMEA, validation plans, and test protocols for pack-

level performance, lifecycle, thermal, and abuse tests.
Lead charge/discharge cycle testing, aging studies, and thermal runaway

simulations.
Coordinate with external labs for certifications (e.g., UL 9540A, UN38.3, IEC

62619, etc.).
Analyze test data for SoH, SoC, degradation, impedance, and thermal

characteristics.
Generate detailed design reports, validation reports, and compliance

documentation.
Work with component vendors (cells, BMS, thermal materials) for

specifications, sourcing, and testing.
Interface with internal engineering, field, and manufacturing teams to

integrate design feedback and optimize production feasibility

Required Qualifications:
B.E./B.Tech or M.E./M.Tech in Electrical, Electronics, Power Systems, or Mechatronics.
3+ years’ experience in battery pack design, thermal/electrical integration, and validation.
Deep understanding of Li-ion chemistry (LFP/NMC) , Li-ion cell behaviour, SoC/SoH metrics, and degradation mechanisms.
Solid knowledge of BMS design, CAN communication, and thermal runaway mitigation.
