Test Engineer - Equipment & Cloud QA (Chinese-Speaking)

MyHR Partner, Inc•Langhorne, PA

3d•$70,000 - $90,000•Onsite

About The Position

Fortress Power designs and manufactures residential and commercial battery energy storage systems. As their Test Engineer for Equipment & Cloud QA, you will own quality control and validation testing across the full product lineup, from physical hardware (batteries, inverters, gateways, and firmware) to the Fortress cloud platform, portal, and mobile/web applications. This is a hands-on, self-directed role for someone who treats quality as a craft and takes full ownership of their domain. You will write and execute test cases, track results and defects in Jira, verify that products behave correctly before they reach customers, and drive issues to closure across firmware, hardware, and software releases. You will serve as the critical quality bridge between U.S. and China-based engineering teams, working in Mandarin to unify test procedures and resolve defects directly at the source.

Requirements

Bachelor's degree in Engineering (Electrical, Software, Controls, Mechanical, or related) or equivalent hands-on technical experience.
Professional fluency in Chinese (Mandarin), written and spoken, for technical defect discussions with overseas engineering and manufacturing teams.
2+ years in product testing, QA, or hardware/firmware/software validation, ideally in energy storage, power electronics, or a comparable hardware+software environment.
Hands-on experience authoring and running test cases, documenting defects, and tracking them to resolution in Jira (or a comparable tool).
Comfort testing across hardware, firmware, and software/cloud layers and comparing behavior between them, including basic log and telemetry analysis.
Authorized to work in the U.S. and able to work on-site in Langhorne, PA.

Nice To Haves

Direct experience with battery energy storage systems (BESS), inverters, or power electronics, including bench testing with lab instrumentation (e.g., multimeter, oscilloscope, power analyzer, programmable loads/sources).
Familiarity with communication protocols (Modbus, CAN bus, RS485, MQTT) and firmware/version management across embedded devices.
Awareness of relevant safety/interconnection standards (e.g., UL 9540, UL 1741, IEEE 1547) and their role in product validation.
Exposure to EMS/SCADA environments, cloud monitoring (e.g., Azure), or basic test automation/scripting.
Experience unifying test procedures across distributed or overseas (China-based) engineering teams.

Responsibilities

Author & run test cases: write, maintain, and execute standardized functional, integration, and system-level test cases against residential and C&I batteries, inverters, gateways, and firmware.
Edge & negative testing: test boundary conditions, fault handling, and error paths — not just the happy path — to surface defects before customers do.
Regression testing: re-run affected cases after firmware/software changes to confirm fixes hold and nothing previously working has regressed.
Bench & lab testing: validate battery, inverter, and gateway behavior on the bench using standard lab instrumentation; reproduce reported field issues in a controlled setup.
Firmware validation: verify ARM, DSP, and LCD firmware builds and version compatibility across products before release.
Log analysis & root cause: pull and analyze device logs and telemetry to isolate root cause and give engineering a reproducible defect.
Validate platform behavior: verify Fortress portal, cloud platform, Installer app, and Homeowner app behavior against device-level data so what customers see matches what systems are doing.
Find cloud/software defects: surface issues in data integrity, reporting, connectivity, and dispatch reflection, and confirm fixes before customer exposure.
Track in Jira: log, prioritize, and track test results and defects in Jira; keep tickets clear, reproducible, and current through to verified closure.
Release notes & QA sign-off: maintain release notes, publish version releases and product news, and provide final QA review before a build is released to production.
Release tracking: keep the test process and release-tracking system current so status is visible at any time.
Coordinate overseas: unify test steps between the China and U.S. teams and drive defect resolution directly with China-based engineering and manufacturing in Chinese (Mandarin).
