Validation Engineer - EV Charger

EXICOM TELE-SYSTEMS LTD.

Job Description

Position: Validation Engineer – EV DC Fast Charging (EVSE)

Location: Gurgaon, Haryana, India

No of position: 1

 

Exicom is scaling its EV DC fast 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.

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, RS485, Modbus RTU.

•      Test protection and safety functions: insulation monitoring, earth leakage/RCD behaviour, over-voltage/over-current/over-temperature protection, emergency stop, and isolation/contactor sequencing per IEC 61851 and relevant functional safety concepts.

•      Perform PCB-level and sub-system testing, including bring-up validation of new hardware revisions.

4. Test Automation & Tooling

•      Develop and maintain Python-based automated test scripts/frameworks for regression, protocol conformance, and endurance testing across the charger fleet.

•      Build log capture/analysis tooling to accelerate root-cause diagnosis.

5. Documentation & Cross-Functional Collaboration

•      Produce clear validation test reports, test summaries, and executive-level status updates

•      Work closely with CFT team throughout the product development lifecycle

•      B.Tech / Diploma in Electrical, Electronics, Power Electronics, or related engineering discipline.

•      2 – 4+ years of experience in power electronics, or embedded systems validation.

•      Demonstrated hands-on experience testing EV DC fast chargers

•      Proficiency in Python for test automation; familiarity with log parsing and data analysis workflows.

•      Experience with lab instrumentation — DC electronic loads, power analyzers, oscilloscopes, insulation testers, EV simulators/emulators.

•      Strong analytical and structured problem-solving ability

•      Ability to work independently under program timelines while maintaining rigorous documentation discipline.

•      Clear written and verbal communication for cross-functional and customer/lab-facing reporting.

•      Process orientation with working knowledge of QMS/validation documentation practices.

•      Proficient in MS Office
