THE INTERNSHIP

Our summer internship is an 8-week program for exceptional students who have learned to find answers in messy, real-world data and want to become outstanding software engineers. You’ll join a small engineering team, work directly with our CTO, and build products that some of the most sophisticated investment firms in the world use.

Students who come to engineering through data science, statistics, or quantitative research bring a rare instinct: they move quickly through ambiguous data to an answer. We build on that instinct and teach the engineering discipline that turns fast analysis into reliable software. Our engineers average more than 16 years of experience, and teaching is part of how we work. Expect real code review, direct feedback, and mentorship that is hard to find at a company of any size.

WHAT YOU WILL BUILD

This is not a summer of bug tickets. Interns prototype new products, often directly with clients. Past interns built MCP integrations and insight dashboards in partnership with clients managing more than $1 billion in assets.

- Client-facing prototypes. Work with our team and our clients to turn a real problem into a working product, then iterate on their feedback.

- AI that works with fund data. Build MCP servers and LLM-powered workflows that let AI tools reason over real fund data, and measure where they succeed and where they fail.

- Insights investors act on. Build dashboards and analytics that help fund managers and their investors understand performance, exposure, and risk.

- Messy data made trustworthy. Fund statements, capital account reports, and general ledgers arrive as PDFs, spreadsheets, and emails in every format imaginable. Help turn them into structured data, with every number traced back to its source.

- A project you own. Every intern owns a project from first prototype to delivery, and presents it to the company at the end of the summer.

WHAT YOU WILL LEARN

- How production software gets built: version control, code review, testing, CI/CD, and running services people depend on.

- How to work in a modern TypeScript and Python codebase, with AI coding tools at the center of the workflow.

- How private markets actually work: funds, capital calls, NAV, and the accounting underneath them.

- How senior engineers think about correctness, design, and tradeoffs, by working alongside them every day.

WHAT YOU NEED

- Pursuing a bachelor’s degree in data science, statistics, computer science, mathematics, economics, or another quantitative field, graduating in 2028 or 2029.

- Strong Python and SQL, and real experience with messy data from research, coursework, a job, or your own projects.

- You’ve taken an analysis from raw data to an answer someone acted on.

- A real interest in becoming a software engineer.

- Available full-time for all 8 weeks, 4 days per week on-site in New York City.

NICE TO HAVE

- Experience with TypeScript, React, or building a web application.

- Research experience, a data competition, or a shipped side project.

- Interest in finance, investing, or how markets work.

- You use AI tools (Claude, ChatGPT, Cursor, or similar) in your daily work.

WHO YOU ARE

- You’re exceptionally bright and you learn fast.

- You’d rather ship something and improve it than wait for perfect.

- You care whether the answer is right, not just whether the code runs.

- You’re comfortable explaining your work to clients and teammates.

- You ask good questions and take feedback without ego.

- You want to be pushed, and you’re ready for a summer with real stakes.
