高级固件DVT工程师 - BESS

Join our dynamic teams designing and developing next-gen energy technologies and help drive a sustainable future!

About the Role

This position sits within our Testing group, where you will work with a small team to develop fully functional prototypes that demonstrate new, advanced operation and control for autonomous grid connection, management, and regulation.

As a Senior Firmware DVT (Design Verification Test) Engineer, you will contribute to the verification and test of Enphase's inverter firmware, gateway, and cloud functions and communications - ensuring they meet engineering requirements, design specifications, and worldwide safety and grid standards.

What You Will Do

• Develop test strategies and plans to verify that Enphase's inverter firmware, gateway, and cloud functions and communications perform per engineering requirements and design specifications.
• Develop and execute test strategies to ensure safety and optimal functionality of Enphase's firmware to meet worldwide standards.
• Design and implement automated test systems in Python and Ruby, enabling continuous integration for the firmware development team.
• Validate firmware communication interfaces and protocols (e.g., Ethernet/TCP-IP, Modbus/TCP, I2C, SPI, UART, SMBus, and power line carrier) using protocol and logic analyzers.
• Collaborate with hardware and firmware engineers to ensure firmware is designed for test.
• Confer with Quality Assurance, Development, and Product Management on project planning, and ensure effective testing of Enphase's firmware within design constraints.
• Use test automation, power meters, oscilloscopes, DC supplies, and other lab test equipment to ensure complete functional, efficiency, and safety test coverage for Enphase's hardware and firmware.
• Coach and train new members of the technical staff on Enphase's test equipment, procedures, and automation software.

Who You Are and What You Bring

• BS/MS in Electrical Engineering, Electronics Engineering, and/or Computer Science.
• 5+ years of experience in a similar role as an embedded firmware test/DVT/QA engineer.
• Strong Python programming for controlling test equipment, test framework development, and test automation, including Python bindings for Linux and communication packages (TCP/IP sockets, SMBus, pyModbusTCP, PiCloud, etc.).
• Functional validation experience with Ethernet/I2C/SPI/UART/power line carrier-based communication systems, and use of protocol and logic analyzers.
• Experience across the stages of embedded firmware (preferably Linux/RTOS-based) design, implementation, test, deployment, and maintenance.
• Experience with firmware integration and testing.
• Experience with 800V-1500V high-voltage DC and 277/480V three-phase AC voltages.

What Will Make You Stand Out

• Basic knowledge of relevant worldwide standards such as IEEE 1547, 1741 SA, CA Rule 21, HECO SRD 1.1, AS/NZS 4777.2:2015, SAND2013-9875, UK G83/2, and Sandia standards.
• Knowledge of worldwide advanced grid functions and fault conditions.
• Familiarity with AC grid simulators and solar panel simulators.
