Charging Test Engineer

Purpose

Execute the DC fast charging (DCFC) acceptance test plan within the planned schedule, and repeat the same process for future charging equipment

Responsibilities

Test execution

• Execute test cases by priority (P0, then P1, then P2) on any vendor's charging equipment: functional, power delivery and sharing, interoperability, thermal, efficiency, fault response, back-end (OCPP), and reliability tests
• Coordinate vehicle availability with Ops and run tests with fleet vehicles or EV/battery emulators, as the test plan specifies
• Collect measurement data (power analyzer, thermal camera, thermocouples, charger, vehicle, and OCPP logs) and report pass/fail results with evidence in the standard report template
• Log defects with reproduction steps and data, follow them through vendor root-cause analysis and fixes, and run regression tests
• Track uptime, connectivity, and session-success KPIs against their targets

Test automation

• Write scripts to automate repeatable test cases in the test plan, for example OCPP-driven session sequences, multi-session power-sharing runs, endurance cycles, and KPI calculation
• Build data-processing tools that merge instrument and log data and compute results against pass/fail limits
• Keep tools vendor-agnostic, version-controlled, and documented

Test site bring-up (secondary)

• Support setup of new test sites for the selected hardware: instrumentation installation and calibration, network and data-logging setup, and witnessing vendor commissioning
• Maintain a reusable bring-up checklist and test setup diagrams

Safety

• Follow high-voltage safety procedures, lockout/tagout, and site rules, and stop any test that is unsafe.

Qualifications

Required

• BS in Electrical, Electronics, or Computer Engineering, or equivalent experience.
• 3+ years of hardware test or validation experience with power electronics, EV charging, or energy systems.
• Safe hands-on work with high-voltage DC and 480 VAC three-phase equipment.
• Experience using power analyzers, oscilloscopes, current and voltage probes, thermal cameras, and data acquisition (DAQ) systems.
• Python or similar scripting for test automation and data analysis; experience with Git.

Preferred

• Experience with DCFC protocols and standards: CCS, NACS (SAE J3400), ISO 15118 / DIN 70121, OCPP, and UL 2202 / IEC 61851.
• Experience with EV/battery emulators or CharIN conformance testing.
