We create data that drives the global clean energy transition. Our team pioneered extended reliability and performance product testing that unlocks investments in solar power. We are passionate about our work because it makes an impact – and we have fun doing it!

Kiwa PVEL is the leading reliability and performance testing lab for downstream solar project developers, financiers, and asset owners around the world. As part of the larger Kiwa Group, Kiwa PVEL’s integrated services for the solar supply chain offer technical solutions for mitigating risk, optimizing financing and improving solar and energy storage systems performance throughout the project lifecycle. For over a decade, Kiwa PVEL’s Product Qualification Program (PQP) has been globally recognized for replacing assumptions about PV module performance with quantifiable metrics.

Related data and consulting services offered by Kiwa PVEL provide vital procurement intelligence to a network of downstream solar buyers.

The Role:

As a Calibration Engineer at Kiwa PVEL, you will play a critical role within our Engineering team, ensuring the accuracy, reliability, and operational readiness of laboratory and field equipment essential to PV module testing. Based onsite in Napa, CA, you will serve as our primary dedicated calibration resource, independently managing calibration activities, equipment verification, troubleshooting, and quality documentation to maintain the technical standards required for accurate, defensible test results.

This is a highly independent, hands-on position requiring strong technical judgment, initiative, and accountability. You will take ownership of calibration-related challenges, proactively identify and resolve equipment issues, and manage competing priorities to minimize disruptions to laboratory operations, testing schedules, and data integrity.

While collaborating closely with Engineering, Quality, and Laboratory Operations, you will be the primary point of accountability for a function essential to our laboratory's success. Your work directly supports the delivery of trusted testing data, strengthens our laboratory's credibility, and contributes to informed global clean energy investments.

• Verify and calibrate equipment (e.g., power supplies, flash testers) to maintain performance within specification.
• Maintain calibration schedules and primary references to ensure equipment readiness.
• Validate test setups and ensure data is properly collected and stored.

Quality Systems & Documentation

• Update and maintain work instructions and test procedures.
• Support quality initiatives and resolve equipment-related quality issues.
• Draft and refine Standard Operating Procedures (SOPs) and Work Instructions.

Testing Support

• Support module reliability testing under PVEL’s Product Qualification Program (PQP).
• Troubleshoot and resolve test excursions and data acquisition issues.
• Ensure testing equipment is operational and aligned with test plans.

Data & Reporting

• Review, analyze, and validate test data.
• Contribute to the development of analysis scripts and reporting templates.
• Address technical questions from clients and support visits/inquiries.
• Assist in designing and implementing new engineering tools and systems.
• Support software development in Python for instrumentation and analysis.
• Provide repair and maintenance support for lab equipment and coordinate subcontractor services.
• Work closely with Quality, Operations, and Client Services teams.
• Travel occasionally to support our Davis test site and other lab locations.
• Other duties as needed.

Skills to be successful:

• Strong attention to detail with a commitment to high-quality work.
