Job Summary:

We are seeking a highly motivated and technically proficient Battery Management Systems (BMS) Engineer to design, develop, and validate BMS solutions for electric vehicles (EVs), energy storage systems (ESS), or battery-powered applications. The ideal candidate will have experience working with high-voltage battery systems, embedded control software, and battery safety protocols.

Key Responsibilities:

  • Design and develop Battery Management Systems (hardware & software) for lithium-ion and other advanced battery chemistries.
  • Define system architecture including cell monitoring units (CMU), battery control units (BCU/VCU), and power distribution.
  • Develop and validate SOC (State of Charge), SOH (State of Health), SOP (State of Power) estimation algorithms.
  • Interface with embedded software teams to develop firmware for real-time control, protection, and communication.
  • Work on thermal management strategies and battery pack protection mechanisms.
  • Develop and maintain CAN, SPI, UART communication protocols and diagnostics (UDS, OBD).
  • Integrate BMS with other vehicle systems such as inverters, chargers, and telematics.
  • Conduct simulation, HIL (Hardware-in-the-Loop), and bench-level testing for performance validation and fault analysis.
  • Ensure compliance with functional safety standards (ISO and battery certifications (UN 38.3, AIS 048, IEC
  • Work with cell vendors, pack designers, and external test labs to optimize system performance and reliability.
  • Create detailed technical documentation, test plans, and reports for internal and regulatory use.

Required Skills & Qualifications:

  • Strong understanding of Li-ion battery chemistry, cell balancing (passive/active), and battery pack architecture.
  • Experience with MATLAB/Simulink, Altium Designer, LTspice, or PSIM.
  • Proficiency in embedded C/C++, especially for automotive-grade microcontrollers (TI, ST, NXP, etc.).
  • Hands-on experience with CAN tools (CANalyzer, CANoe), ETAS INCA, and diagnostic protocols.
  • Experience with safety-critical system design, FMEA, ISO 26262, and ASIL levels.
  • Familiarity with battery testing equipment: cyclers, impedance analyzers, thermal chambers, etc.

Preferred/Bonus Skills:

  • Knowledge of Battery Cell Modeling and Electrochemical Impedance Spectroscopy (EIS).
  • Experience in EV architecture, working on VCU-BMS integration.
  • Exposure to cloud-based BMS monitoring systems (IoT for battery diagnostics).
  • Experience in automotive standards such as ISO 15118, ISO 21434, and AUTOSAR.
  • Knowledge of battery pack design, mechanical constraints, and thermal simulation tools (e.g., ANSYS, FloTHERM).
