Job Description: Li-ion  & BESS Electrical Integration Design Engineer

Role Overview

The Li-ion & BESS Electrical Integration Design Engineer will design, integrate, and validate electrical systems for Lithium-Ion Battery (LiB) packs and Battery Energy Storage Systems (BESS).

Key Responsibilities

• System Architecture: Develop electrical integration layouts for LiB modules, packs, and BESS systems.

• Design Validation: Conduct electrical simulations, short-circuit analysis, and fault-tree evaluations.

• Standards Compliance: Ensure designs meet UL, IEC, ISO, and UN 38.3 standards.

• Thermal & Electrical Integration: Collaborate with mechanical and thermal teams.

• Digital Tools: Use ECAD/MCAD, ANSYS, MATLAB/Simulink, digital twin methodologies.

• Cross-Functional Collaboration: Work with product design, manufacturing, and compliance teams.

• Failure Analysis: Investigate electrical failures and implement improvements.

• Documentation: Prepare design reports and compliance documentation.

Qualifications

• Bachelor’s/Master’s in Electrical Engineering, Power Electronics, or Energy Systems.

• 3–7 years of experience in Li-Ion battery pack design or BESS integration.

• Knowledge of high-voltage systems (up to 1500V DC).

• Working experience with simulation tools (ANSYS, MATLAB/Simulink, PSpice).

• Familiarity with manufacturing processes for battery modules.

• Understanding of safety standards and compliance requirements.

Key Skills

• Electrical integration & harness design

• High-voltage safety & protection systems

• Simulation & modelling (thermal, electrical, fault analysis)

• Standards compliance & certification readiness

• Cross-functional leadership in design-to-manufacturing transitions
