 * 7+ years in test or validation engineering, including 4+ years on embedded firmware and 2+ years leading or mentoring test engineers.
 * Strong Python skills and daily comfort in Visual Studio Code, plus Git and CI/CD tools such as GitHub Actions.
 * Proven track record designing firmware validation test cases and running structured regression programs.
 * Hands-on experience with embedded interfaces (UART, SPI, I2C, CAN, Modbus, or TCP/IP) and lab equipment such as oscilloscopes, power supplies, electronic loads, solar array simulators, and temperature chambers.
 * Advanced Jira skills and clear written communication for technical and non-technical audiences., * Background in solar PV, energy storage, BMS, inverters, or power electronics, including standards such as UL 9540, UL 1741, UL 1973, and IEEE 1547.
 * Experience building HIL test systems or using LabVIEW for instrument control.
 * Working knowledge of C/C++ for reading and debugging firmware source.
 * Experience with Jama or TestRail, IoT devices, or OTA update validation., Candidates must be authorized to work in the United States on a full-time basis without the need for current or future employer sponsorship.

## Description

* Turn requirements and firmware specs into traceable test plans covering functional, boundary, stress, power-cycling, and fault-injection cases.
 * Validate OTA updates, bootloaders, communication protocols, battery and power-management behavior, and safety features.
 * Build and maintain hardware-in-the-loop (HIL) benches and run environmental and inverter system-level testing on the Yotta Block.
 * Own the regression strategy (smoke, sanity, full), run cycles for every release candidate, and separate real defects from test or environment issues.

Team Leadership

 * Lead and mentor test engineers and technicians, set priorities, and support hiring and onboarding.
 * Set test standards and coding guidelines, and own lab organization, safety, 5S practices, and test fixtures.
 * Represent test in sprint planning, design reviews, and release go/no-go decisions.

Test Management & Collaboration

 * Manage the test backlog, sprints, and defect workflow in Jira, with traceability in Jama or TestRail and dashboards on release readiness.
 * Work with firmware, hardware, and field engineering to root-cause issues, including those reported from deployed sites.
 * Support certification testing (UL 9540, UL 1741, UL 1973, IEEE 1547) and document procedures and results in Confluence.
