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.
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
Requirements & Tech Stack
- Pursuing a degree in Computer Science, Software Engineering, or a related field (Junior, Senior, or graduate student preferred)
- Coursework or experience in:
- Software development fundamentals
- Web or backend programming
- Familiarity with at least one of:
- TypeScript / JavaScript
- Go or Python
- Basic understanding of:

- Data visualization or real-time systems
- Exposure to:
- Containers (Docker)
- Time-series or telemetry data
- At least 6 months of previous internship, co-op, or academic project experience outside of normal classes
- GPA of 3.5 or above
- Basic experience with CAD Software, MATLAB, Python, or Excel
What We Offer
- Real resume-building engineering experience
- Mentorship from experienced engineering professionals
- Exposure to the full product development lifecycle
- A collaborative and learning-focused work environment
- Daily catered lunch and unlimited snacks provided
- An unforgettable summer!
