Validation Engineer - EV Charger

Exicom; Gurugram District; On-site; INR 800,000 - 1,200,000; Full time

Job summary

Exicom is scaling its EV DC fast charging portfolio and seeks a Validation Engineer to own end-to-end product validation for 30 kW to 1000 kW chargers. You will design test strategies from SRD/PRD, execute automated tests, and drive certification readiness.

This hands-on role requires experience with IEC 61851, ISO 15118, OCPP, CAN, RS232/RS485, and lab instrumentation; you will analyze results, generate reports, and collaborate with cross-functional teams to ensure robust field interoperability

Qualifications

• 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.

Responsibilities

• Develop validation test plans, test cases, and acceptance criteria from SRD/PRD, ensuring full traceability.
• Define validation strategy across product lifecycle stages.
• Validate EV-EVSE communication per IEC 61851-1, CCS2 physical layer, and ISO 15118.
• Conduct conformance and interoperability testing against ISO 15118, DIN SPEC 70121, including session setup and parameter discovery.
• Execute Plug & Charge (PnC) validation and test OCPP 1.6J & 2.0.1 message flows between charger and CSMS.
• Test protection and safety functions per IEC 61851 and functional safety concepts.

Job description

Role Summary

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.

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 to 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

Required Qualifications & Experience

• 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.
