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 rapid 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 int
