Machine Learning Engineer, Applied AI Co-Op Intern, Winter 2027

Why Now

Brain Co. is entering its next phase of production deployments on a national scale with an elite team built from Palantir, Google, Meta, and Nvidia, and a growing footprint across government, insurance, health, and financial services.

Joining now means shaping both the company and a new category of applied AI. Every project here ships to production and is expected to create measurable customer value and impact.

You'll work alongside exceptional peers on some of the hardest problems in applied AI. It’s the kind of work you'll still be proud of in ten years from now.

About the Co-Op:

As an AI/ML Engineer Co-op Intern, you’ll work alongside experienced engineers and researchers to help design, build, and deploy machine learning systems that solve high-impact problems in healthcare, government, and energy.

This internship is designed for current undergraduate students (juniors and seniors) who want hands-on experience applying modern AI techniques—especially large language models—to real-world challenges. You’ll gain exposure to the full ML lifecycle while receiving mentorship and ownership over meaningful projects.

What You’ll Do

* Assist in designing and deploying LLM-powered applications to automate complex, real-world workflows

* Build and improve data pipelines and support model training, evaluation, and optimization

* Work with structured and unstructured data (e.g., text, documents, logs)

* Help prepare models and systems for production deployment and monitoring

* Collaborate closely with senior engineers, AI researchers, and product teams

* Learn best practices through code reviews, design discussions, and hands-on mentorship

* Gain exposure to customer-facing and real-world constraints, including working with public-sector institutions

You Might Be a Good Fit If You

* Are a current undergraduate student, specifically a junior or senior, pursuing a degree in Computer Science, Machine Learning, Data Science, or a related field

* Have experience programming in Python

* Have coursework or project experience in machine learning or AI

* Have exposure to or interest in large language models and GenAI applications (e.g., agents, RAG, reasoning workflows)

* Have used or are eager to learn frameworks such as PyTorch, JAX, or TensorFlow

* Have strong fundamentals in data structures and algorithms
Are curious, proactive, and excited to learn quickly in a fast-paced environment

* Enjoy owning problems end-to-end with guidance and support
