Key Responsibilities

• Assist in designing and developing end-to-end AI applications, from prototype through deployment
• Build and iterate on AI agents, workflows, and tool integrations (e.g., MCP servers, agentic pipelines)
• Contribute to production-grade forecasting or classification systems with attention to latency, scalability, and robustness
• Help develop full-stack AI applications with both frontend and backend components
• Work with proprietary research data to train, evaluate, and improve ML or GenAI models
• Participate in code reviews, design discussions, and cross-functional collaboration with analysts and investors

Academic & Experience Requirements

• Currently pursuing a Master’s or Bachelor’s degree in Computer Science, Machine Learning, Data Science, or a related field

• Familiarity with cloud platforms (AWS preferred—SageMaker, Bedrock, or similar)
• Comfort with Git, containerization basics (Docker), and command-line workflows
• Interest in or experience with agentic coding tools (e.g., Claude Code, Codex) and AI workflow frameworks

Nice to Have

• Experience with LLM application development (prompt engineering, RAG, fine-tuning)
• Familiarity with agent frameworks, MCP integrations, or multi-agent architectures
• Experience building data pipelines or working with large-scale datasets
• Contributions to open-source projects or a strong personal project portfolio

What You’ll Gain

• Hands-on experience building AI systems that directly impact investment decisions in breakthrough medical and climate technologies
• Mentorship from senior engineers and exposure to a proven team of analysts and investors
• Access to extensive proprietary datasets and real-world AI/ML challenges at production scale
• A collaborative, sandbox-style environment where our work feels like play—and when our investments succeed, people live longer, healthier lives

Additional Requirements

• Excellent English communication skills for collaboration with team members and stakeholders
• Strong problem-solving abilities and investigative mindset
• Ability to work in a collaborative, mentorship-driven environment
• Must be authorized to work in the United States for the duration of the internship
• Must be able to work out of our Boston office this summer
• Ability to join us on June 1st and commit full-time for 10-12 weeks
