Charging Systems Engineer

At Tata Technologies we make product development dreams a reality by designing, engineering and validating the products of tomorrow for the world’s leading manufacturers. Due to our continued growth we are now recruiting for a Embedded Charging Systems & EV Power Electronics Engineer to be based at our customer’s site in Warwickshire.

Our Embedded Systems Solutions department (ESS) encompasses all activities outlined under the Automotive SPICE (ASPICE) process framework, including systems engineering, software engineering, coding, and all levels of functional testing. Beyond core development, ESS also integrates critical supporting processes such as project management, risk assessment, functional safety, and cybersecurity, ensuring compliance with ASPICE standards and delivering reliable, secure, and high-quality embedded systems & solutions.

To lead validation, testing, diagnostics, and continuous improvement activities across DCDC converters, onboard chargers (AC and DC), EV charging systems, and vehicle high voltage (HV) electronics. The role requires hands on expertise with test equipment, CAN based diagnostics, HV systems, and cross functional collaboration to support vehicle programs.

• Execute validation and verification for:
• CCS, CHAdeMO, Type2, GB/T, NACS, Type1/Type5 charging protocols
• Chargingrelated
  
  BMC/HV release features for multiple vehicle platforms
• Perform functional, performance, and robustness testing for EV charging systems.
• Develop test plans, test cases, and test scripts based on system requirements.
• Conduct vehicle leveltesting, including EVSE checks, charging simulations, power analysis, and diagnostic tools usage.
• Capture logs, analyse data, andidentifyroot causes for charging failures or communication issues.
• Verify SIMS/AMS/BUGS issue fixes on vehicles/HIL/VIL setups.
• Work withcross functional teams (software, hardware, systems, diagnostics) to resolve defects.
• Ensure compliance with standards (ISO 15118, IEC 61851, DIN 70121, ISO 26262).
• Prepare detailed test reports and present findings to engineering leadership.
• Contribute to continuous process improvement and validation lifecycle enhancements.

• Hands‑on experience with EV charging systems, power electronics, or vehicle HV electrical systems.
• Strong understanding of CAN, LIN, PLC communication, Ethernet, and diagnostic tools (Vector
  
  CANoe/CANalyzer).
• Experience with charging protocols (CCS Combo, CHAdeMO, GBT, Type2, Type1/Type5).
• Ability to interpret schematics, wiring diagrams, and system/vehicle requirements.
• Strong analytical and problem‑solving skills.
• Experience with test equipment:
  • Multimeters
  • Charging simulators
• Ability to work independently in a fast paced environment.
• Experience working in lab and vehicle test environments.
• Experience with high voltage systems (400V / 800V).
• Knowledge of standards: ISO 15118, IEC 61851, DIN 70121, ISO 26262.
• Experience with vehicle level diagnostics and fault analysis.
• Understanding of safety procedures & risk assessments.
• Hands‑on experience with Vector/ETAS tools.
• HVAC or SPA knowledge (preferable).
• EV/EVSE Class3 driving permit (as required by project).
