A day in the life
As a Reliability Engineer, you'll drive cell-package interactions and module-level reliability, addressing the unique challenges of a first-generation technology moving from concept through certification and towards manufacturing.
On a typical day, you might schedule and execute reliability tests on tandem mini-modules and full modules—spanning environmental, thermomechanical, and accelerated life tests such as damp heat, thermal cycling, UV, and outdoor exposure—then evaluate the results. You might perform failure analysis on tandem modules, design a non-standard accelerated stress protocol to reproduce a field failure, or coordinate third-party testing with external labs.
You'll contribute a reliability perspective, collaborate with the Product Management team on lifetime modeling, and develop hypotheses you communicate clearly to the Materials R&D, Process Engineering, and Product Development teams. As an early hire, you'll help shape how the reliability function operates as the team grows and interacts with every part of the company along the way.
You might be a good fit if you…
- Have 3–5 years of experience in PV module reliability, spanning from R&D to third-party validation and certification.
- Have a demonstrated ability to diagnose failure mechanisms and translate findings into data-driven insights for cross-functional teams.
- Have experience working with external testing labs to define and complete testing.
- Have a solid understanding of PV cell and module device physics.
- Have a proven ability to work well with cross-functional teams (R&D, Product Development, Engineering, Manufacturing), showing strong communication and empathy.
- Are proficient in statistical analysis software (e.g., JMP) and the application of statistics to reliability analysis.
A strong candidate might bring
- Experience with more than one PV cell type.
- Experience developing non-standard accelerated testing protocols for a first-generation technology.
- Familiarity with reliability engineering tools (e.g., FMEA, 8D, RCA, DFR).
- Experience sourcing reliability test equipment.

Compensation: Competitive package including salary, equity, and benefits
Expected Pay Range: $110,000 - $150,000 per year. The actual offer, reflecting total compensation and benefits, will be determined by factors such as relevant experience, skills, and other qualifications.
Ideal start date: July-August 2026
What you'll love
- Work with purpose on advancing solar energy technology.
