Senior Engineering, Test Engineering

Yotta Energy is the leading-edge solar storage solution. We simplify solar energy storage using decentralized, panel-level storage and optimize energy efficiency with intelligent software. Through our flagship product, SolarLEAF™ , we’ve pioneered a modular storage solution with smart thermal regulation that integrates behind each photovoltaic (PV) panel while maximizing the life and performance of the battery. Yotta Energy has since added YB-1 (Yotta Block) to our list of products.
Yotta Energy is looking for a Senior Test Engineer to lead test and validation for firmware and embedded systems that power our distributed solar + storage products. You will own the test strategy end to end: designing firmware validation and regression test cases, building and maintaining automated test scripts in Visual Studio Code, and guiding a small team of test engineers and technicians.
You will write code and run tests alongside your team, manage test work in Jira, and partner closely with firmware, hardware, and product teams to make sure every release ships with confidence. Build and maintain Python/pytest test scripts and frameworks in Visual Studio Code that drive devices over serial, CAN, Modbus, Ethernet, and wireless interfaces.
Build and maintain hardware-in-the-loop (HIL) benches and run environmental and inverter system-level testing on the Yotta Block.
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.
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.
Bachelor’s degree in Electrical, Computer, or Software Engineering, Computer Science, or a related field (or equivalent experience).

• 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.
• 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.
Lift, move, push, and pull 30-50 lb frequently (over 50 lb occasionally, with assistance).
Work outdoors in adverse weather, including hot and cold temperatures.
Opportunity to work on innovative clean energy technologies

• Career growth and professional development opportunities
• Exposure to cutting-edge energy management and cloud technologies
• Candidates must   be authorized to   work in the United States on a full-time basis without the need   for current or future employer sponsorship.
