EXICOM TELE-SYSTEMS LTD.
Job Description
Position: Validation Engineer – EV DC Fast Charging (EVSE)
Location: Gurgaon, Haryana, India
Role Summary
Exicom is scaling its EV DC quick charging portfolio across 30 kW to 1000 kW power classes. The Validation Engineer owns end-to-end product validation for these chargers — spanning communication protocol conformance, power electronics performance, embedded firmware behaviour, environmental/reliability stress, and regulatory/certification readiness. This is a hands-on engineering role requiring the ability to independently design test strategies against system requirements, execute and automate tests, root-cause field and lab failures, and produce certification-grade validation reports.
Key Responsibilities
1. Test Strategy, Planning & Requirements Traceability
Develop validation test plans, test cases, and acceptance criteria directly from system/product requirement documents (SRD/PRD), ensuring full requirement-to-test traceability.
Define validation strategy across product lifecycle stages
2.



Communication Protocol & Interoperability Validation
Validate EV-EVSE communication per IEC 61851-1 (Control Pilot/Proximity Pilot states, PWM duty cycle), CCS2 physical layer, and HomePlug Green PHY (HPGP) SLAC matching (ISO 15118).
Conduct conformance and interoperability testing against ISO 15118, DIN SPEC 70121, including session setup, charge parameter discovery, power delivery, and session stop/error handling sequences.
Execute Plug & Charge (PnC) validation
Test OCPP 1.6J and OCPP 2.0.1 message flows between charger and CSMS
Characterize and validate SLAC timing, CP state gating, timeout/retry handling, and fallback behaviour (ISO 15118 → DIN 70121 degrade paths) for robust field interoperability across multiple EV OEMs.
3. Power Electronics, Firmware & Hardware Validation
Validate AC-DC power conversion modules
Conduct firmware validation of charger controllers
Validate internal communication interfaces — CAN 2.0B, RS232, RS
