Enphase Energy New Zealand — Summer Internship 2026/27

Power Your Summer with Purpose

Want real experience that actually matters? Enphase Energy is opening applications for our Summer Internship Program: 400 hours over 10 weeks, running mid-November to mid-February. You'll need to be available for the full 10 weeks.

At Enphase, we're on a mission to advance a sustainable future for all. This internship is your chance to be part of that work, not just watch from the sidelines.

Seven internship projects are open now. find your fit below!

How to Apply

• Cover letter: tell us which project(s) you're interested in (you can list more than one)
• Resume + transcripts: combine your most recent academic transcripts with your resume into a single document (there's no separate upload for transcripts)
• Applications that don't follow these instructions won't move forward to review, so double-check before submitting.
• Deadline: 8 October 2026

Available Projects

1. Improved Loss Management of Power Transformers: Advance transformer knowledge by evaluating high-frequency core loss mechanisms. Simulate ferrite core losses in FEMM across different core geometries, then hand-prototype physical replicas to test simulation accuracy and identify which core dimensions most affect losses.

2. AI-based Resource Planner: Build an AI-based resource planner using LLM reasoning to generate valid, auditable engineering resource plans from incomplete or ambiguous briefs, integrated with live Jira data. Explore whether LLM outputs can be made deterministic and verifiable enough for commercial use.

3. Custom Switching Device Development: Develop and evaluate an integrated Grid Switch solution through testing, CAD, concept development, and prototyping. Ideal for a Mechanical or Mechatronics student wanting hands-on product development experience.

4. Infrared Test Platform: Design, build, and validate a configurable IR thermal testing platform that simulates real-world rooftop installation conditions. Suited to Mechanical or Mechatronics Engineering students.

5. Magnetics Grinding: Test whether low-cost automated benchtop grinding can produce accurate, dimensionally consistent ferrite core gaps for controlling leakage inductance in IQ-series transformers, a relationship currently uncharacterized for this material and geometry.

6. 2D Optical Inspection of PCAs: Develop a computer-vision-based Automated Optical Inspection (AOI) program to detect component presence and placement defects on low-volume prototype PCB assemblies.

7. NTC Emulation Box: Design and build a device that emulates thermistor behaviour for repeatable testing, combining hardware design, PCB development, and Python test automation for Enphase's safety-critical energy systems.

Who We're Looking For

3rd-year engineering students

Computer Engineering, Software Engineering, Mechatronics, Mechanical or Electrical Engineering majors

Ambitious self-starters comfortable working independently, testing ideas, and learning through experimentation; while knowing when to ask for guidance

Students who haven't previously completed a 400-hour internship

People who enjoy practical, hands-on engineering work

What You Can Expect

A supportive mentor team with access to subject matter experts across the business

Equipment and resources to support your project

Mentorship from experienced engineers throughout your project

* The opportunity to present your findings and recommendations to the engineering team at the end of the internship
