Summer 2027 Internship- Software Engineering

About Pacific Fusion Pacific Fusion was founded in 2023 with the mission to power the world with abundant, affordable, clean energy. We are rapidly designing and building a pulser-driven inertial fusion system to achieve net facility gain (more fusion energy output than stored energy input). In parallel, we are developing the key components required to build affordable fusion systems. Our plans are ambitious. We have raised over $900M so far from incredible investors, resourcing us to deliver on these plans. We are bringing together the best scientists, engineers, and operators from the fusion community, hard tech industry, and other sectors. We are united by a shared sense of urgency to provide clean power for the world, particularly managing climate change while meeting growing global energy demand. You can read more about us in this letter from our founders. Why This Role Matters As a Software Engineering Intern, you will help build the user interfaces and backend software systems that allow engineers, scientists and operators to run the fusion demonstration facility. You will work closely with controls engineers, scientists, and operators to develop software that presents real-time system state, manages configuration and data, and supports safe facility operations.

What You'll Do

Develop and improve web-based user interfaces for

System status and health monitoring Experiment or facility configuration Alerts, events, and diagnostics

Assist in building backend services that

Serve real-time and historical facility data Manage configuration, metadata, and system state Interface with controls systems and data pipelines

Support integration between

UI applications, backend APIs, and facility systems Write clear, maintainable code and contribute to code reviews Help test, debug, and validate software used in live environments What You Bring Pursuing a degree in Computer Science, Software Engineering, or a related field (Junior, Senior, or graduate student preferred)
