Join our dynamic teams designing and developing next-gen energy technologies and help drive a sustainable future!

We're looking for a skilled software developer lead to establish and maintain our software development processes using a framework, ensuring high-quality product delivery and efficient team collaboration. The ideal candidate will have experience in developing and implementing software frameworks for hardware manufacturing test, setting up development workflows, version control, and issue tracking.

This role at Enphase requires working onsite 3 days a week, with plans to transition back to a full 5 day in office schedule over time.

Enphase has multiple high-volume manufacturing and test setups globally. You will support the manufacturing test setup globally and ensure they meet the highest reliability and quality standards in the industry. You will work closely with all production sites to monitor, maintain, and improve test hardware and software. You will also work with the NPI and design teams to successfully introduce new products into production.

The job consists of understanding, supporting, and improving the test technology, strategy, hardware, and software to be deployed at Enphase's various production facilities. Enphase's products often carry a relatively long warranty in the field; therefore, our manufacturing process and test must support the quality required. This often results in unique product features, disciplined manufacturing processes, and rigorous testing.

What You Will Do

• Collaborate with global cross-functional teams (Hardware, Software, Manufacturing, and Quality) to support test systems
• Develop, enhance, and maintain manufacturing test hardware & software for production environments
• Partner with NPI teams to successfully introduce new products into manufacturing
• Design and implement robust, fault-tolerant test systems in collaboration with manufacturing software teams
• Monitor, debug, and support test systems across high-volume global production sites
• Define and document test processes, calibration plans, and preventive maintenance routines
• Drive yield improvement and reliability through test gap analysis and closed-loop feedback from field/RMA failures

What You Bring and Who You Are

• Bachelor's/Master's degree in Electrical/Electronics Engineering or related field
• 4+ years of experience in manufacturing test development (Python, LabVIEW, C/C++)
• Strong expertise in power electronics and test system architecture
• Experience working in high-volume manufacturing environments with test system support
• Proficiency in tools like JIRA, Bitbucket (or similar version control & project management tools)
• Knowledge of SPC/DOE, yield improvement, and manufacturing process optimization
• Strong problem-solving, failure analysis skills, and effective communication across global teams
