Job description

Enphase Energy is a global energy technology company and a leading provider of solar, battery, and electric vehicle charging products. Founded in 2006, our innovative microinverter technology revolutionized solar power, making it a safer, more reliable, and scalable energy source. Today, the Enphase Energy System enables users to make, use, save, and sell their own power. Enphase is also one of the most successful and innovative clean energy companies in the world, with more than 80 million products shipped across 160 countries.

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

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.

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.

Key responsibilities include designing and implementing software development processes, developing reusable frameworks and libraries, and ensuring best practices in coding, testing, and deployment. The candidate should have strong problem‑solving skills, attention to detail, and excellent collaboration and communication skills.

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

• Working with geographically dispersed teams consisting of Electronics Hardware Engineers, Software Engineers, and Engineering Technicians.
• Supporting changes and upgrades to Enphase production test hardware and software.
• Coordinating with the NPI, Manufacturing and Quality teams at contract manufacturing sites.
• Developing and documenting test system processes and maintenance routines, including calibration, replacement schedule, repeatability test, etc.
• Coordinating closely with the Mfg. SW Development Team to design and ensure a fault‑tolerant test system.
• Maintaining, debugging, and supporting the production facilities where the test systems are deployed.

What You Bring And Who You Are

• B.E/M.Tech. in Computer Science or Electrical Engineering, or other suitable educational background or work experience.
• 3+ years of experience in software development using Python in Manufacturing Domain.
• ATE Framework Software Development: Design and develop Automated Test Equipment (ATE) software framework for production testing wherein need to develop reusable Python framework and libraries.
• Application Development: Develop applications with Python that integrate with various instruments and systems.
• Architecture/System Design: Create system designs and architectures for desktop application and cloud (optional).
• Multi-Threading: Implement multi‑threading techniques for concurrent execution of tasks.
• Design Patterns: Apply design patterns for scalability, maintainability, and performance in software development.
• SQL/HTTP/PyQt: Work with SQL databases, develop RESTful APIs, and create GUI applications using PyQt.
