Senior Manager Battery Application Engineering

Function: Battery Engineering | Experience: 8+ years | Location: Hyderabad | Reports to: Vice President Battery Systems & Engineering (or) DGM – Systems Engineering

Role Overview

Lead the Battery Application Engineering function responsible for system integration, commissioning, debugging and field resolution of HV Li-ion battery systems for automotive applications. Act as the key technical interface between Battery Engineering, BMS, Vehicle Engineering, Software, Testing, Manufacturing, Quality and customers to ensure rapid system bring-up and issue closure.

Key Responsibilities

- Own HV battery system integration and application engineering from prototype builds through validation, SOP and field support.
- Lead system bring-up, commissioning and debugging of battery packs integrated with VCU, BMS, inverter, charger, thermal systems and vehicle controls.
- Lead electronic handshaking and communication debugging using CAN/CAN-FD, UDS and related automotive protocols.
- Analyze CAN logs, DBCs, diagnostic messages, DTCs, alarms, protection events and BMS data to identify root causes.
- Troubleshoot complex HV, electrical, electronic, BMS, communication, thermal and system-level issues and drive permanent corrective actions.
- Own field issue resolution and customer escalations, including containment, root-cause analysis, 8D/5-Why and closure.
- Lead battery/system builds, prototype vehicle integration, commissioning and issue tracking across development programs.
- Support BMS application/calibration including SOC/SOH behavior, charge/discharge limits, protection thresholds, thermal derating and fault handling.
- Define application-level requirements, diagnostic strategies, test cases and acceptance criteria.
- Support bench, HIL, pack, dyno and vehicle-level testing, including issue reproduction and validation of fixes.
- Establish robust debugging methodologies, troubleshooting guides, diagnostic workflows and application engineering standards.




- Build and lead a high-performing Battery Application Engineering team, developing strong capabilities in HV systems, diagnostics and integration.

Required Qualifications & Experience

- Bachelor's/Master's degree in Electrical, Electronics, Automotive, Mechatronics, Controls or related engineering.
- 7+ years of hands-on experience in HV Li-ion battery application/system engineering, preferably in automotive/EV applications.
- Proven experience in HV battery integration, system commissioning, electronic handshaking, debugging and field troubleshooting.
- Strong knowledge of BMS architecture, VCU interaction, HVIL, contactors, pre-charge, isolation monitoring, charging and protection systems.
- Hands-on proficiency with CANalyzer/CANoe/CANape, Vehicle Spy or equivalent CAN tools.
- Ability to interpret CAN traces, DBC files, UDS diagnostics, DTCs, system logs and BMS parameters.
- Strong understanding of CAN/CAN-FD and automotive communication architectures; UDS and automotive Ethernet exposure preferred.
- Experience with prototype/system builds, vehicle commissioning and field failure investigation.
- Strong understanding of HV safety and secure working practices.
- Exposure to BMS calibration, embedded software, HIL and battery test systems is an advantage.

Leadership Profile

- Hands-on, analytical and highly execution-oriented problem solver.
- Strong ability to diagnose issues under pressure during builds, launches and field escalations.
- Excellent cross-functional, customer and supplier communication skills.
- Strong ownership, structured root-cause methodology and bias toward rapid closure.
- Proven ability to lead, mentor and develop application engineering teams.

Key Success Outcomes

Fast system bring-up | Robust electronic handshaking | Rapid debugging & issue closure | Reduced field failures | Successful vehicle integration | Strong customer satisfaction | Scalable application engineering processes

Preferred background: EV OEMs, battery manufacturers, BMS companies, Tier-1 automotive suppliers or battery/ESS companies with strong hands-on experience in HV battery integration, diagnostics, commissioning and field engineering.
