Crusoe's mission is to accelerate the abundance of energy and intelligence. We’re crafting the engine that powers a world where people can create ambitiously with AI — without sacrificing scale, speed, or sustainability.

Be a part of the AI revolution with sustainable technology at Crusoe. Here, you'll drive meaningful innovation, make a tangible impact, and join a team that’s setting the pace for responsible, transformative cloud infrastructure.

About the Role:

We are seeking a motivated Summer Intern to help build and experiment with custom agents, large language models, and next-generation cloud technologies. This is a learning-first role—you’ll gain hands-on experience in AI development, cloud workflows, and security tradecraft while contributing to meaningful projects.

This is a 12-week in-person program based in our Bay Area offices. While we have two locations- Sunnyvale and San Francisco, most events and programming will take place in San Francisco.

What you’ll do

• Assist in designing and implementing custom LLMs and fine-tuning models for specific tasks.

• Build and experiment with agent libraries and workflow orchestration frameworks.

• Explore neo-cloud technologies, containerized environments, and virtualized infrastructure.

• Learn and apply security and privacy best practices in AI pipelines and deployments.

• Collaborate with the team to document, test, and optimize agent behaviors and models.

• Participate in knowledge sharing and mentorship sessions, gaining exposure to AI, cloud, and security tradecraft.
