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 Product 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 teams.
- 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 unit level 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 and 8+ years of experience for a staff role
- 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 60V high-voltage DC and 277/480V three-phase AC voltages is a plus
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.
