About Brain Co.
Brain Co. is an applied AI startup founded by Elad Gil and Jared Kushner, backed by many of Silicon Valley’s leading builders—including Patrick Collison (CEO of Stripe), Andrej Karpathy (Cofounder of OpenAI), Mike Krieger (CPO of Anthropic), Kevin Weil (CPO of OpenAI), and Aravind Srinivas (CEO of Perplexity).
We build AI platforms and applications for the world’s most important institutions, delivering real impact on complex, real-world problems.
Our progress so far:
Automated construction permitting for a sovereign government → 80% faster, unlocking $375M+ in value
Optimized supply chains for a global energy leader → 30% lower cost, 99% reliability, preventing $100M+ in losses
Streamlined hospital patient care across national health systems → 40% better outcomes, 80% less admin work
Raised a $30M Series A from top-tier investors
Built a team of 40+ AI experts from Tesla, Google DeepMind, NVIDIA, and Databricks
At Brain Co., interns contribute to real production systems and see their work deployed at global scale.
About the Internship:
As an AI/ML Engineer 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 (sophomores and juniors) 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 sophomore or junior, 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 environmentEnjoy owning problems end-to-end with guidance and support
Internship Details & Benefits
Competitive internship compensation
Hands-on mentorship from experienced AI engineers and researchers
Opportunity to work on real production systems used globally
Potential return-offer consideration for future internships or full-time roles
Daily lunches (if onsite)
Why Intern at Brain Co.
Work on AI systems that have real-world impact, not toy projects
Learn directly from engineers and leaders with backgrounds at Tesla, DeepMind, Databricks, and more
Build practical experience with state-of-the-art AI and LLMs
Take ownership early and grow fast in a high-impact environment
Be part of a culture built on speed, curiosity, and responsibility
If you’re a current sophomore or junior eager to apply AI to meaningful problems at global scale, Brain Co. is a place to learn, build, and make an impact.
