Reliability Test Engineer Alameda, CA

Reliability Test Engineer

Rondo Energy’s mission is to eliminate 15% of global CO₂ emissions in 15 years.

To accomplish this mission, Rondo is deploying low‑cost, zero‑carbon Rondo Heat Batteries to accelerate the deployment of renewable energy and to significantly decarbonize industrial processes that are commonly thought of as "difficult‑to‑decarbonize." Our Heat Batteries charge from intermittent renewables to provide high temperature, continuous heat for customers safely, reliably, at an unprecedented 98% efficiency—and at a cost point that is lower than any other method.

We are looking for an experienced Reliability Test Engineer to join our team and drive innovation in testing thermal and heat transfer systems for industrial heat applications  will be responsible for designing, building, and commissioning custom test rigs and executing tests to demonstrate the reliability of Rondo components and systems.

• Perform and operate tests for accelerated life testing (ALT), highly accelerated life testing (HALT), and highly accelerated stress screening (HASS).
• Develop SCADA/HMI screens and dashboards for custom equipment.
• Write test automation code, via Ignition, Python or similar.
• Assist in conceptual design of custom test equipment.
• Integrate and calibrate various process sensors (temperature, heat flux, power measurement, etc.) to support accurate and reliable testing of thermal systems.
• Prioritize safety by implementing and adhering to safety protocols and industry standards throughout testing processes.
• Assist in building test equipment and fixtures for mechanical, electrical, and thermal testing.
• Analyze test data and provide reports to key stakeholders.
• Assist in developing reliability metrics and lifetime assessments.

• Bachelor’s or Master’s degree in Mechanical/Electrical Engineering, Mechatronics, Thermal Engineering, or a related field.
• 5+ years of experience in operating test equipment and testing systems and components.
• Experience with low voltage control panel design and PLC programming.
• Familiarity with medium voltage and high voltage wiring and customized equipment.
• Proficiency in standard laboratory equipment (oscilloscope, multimeters, power meters, thermocouples, etc.).
• Experience with different sensor types and data acquisition systems.
• Good laboratory practices (GLP) with operating and handling materials involving electromechanical and high temperature applications.
• Familiarity with HALT, reliability testing.
• Good understanding of heat transfer principles and thermal systems testing methodologies.
• Strong analytical and problem‑solving skills, with attention to detail in testing and validation.

• Experience with high‑temperature materials testing (above 1000 °C).
• Knowledge of medium voltage systems and components.

• Life Insurance and ADD.
• Up to 13 paid holidays per year, plus a company week‑long holiday in December.
• Flexible time off policy.
• Catered lunches on‑site.
• 401(k) plan with company match.
