Job description

WorldQuant develops and deploys systematic financial strategies across a broad range of asset classes and global markets. We seek to produce high-quality predictive signals (alphas) through our proprietary research platform to employ financial strategies focused on market inefficiencies. Our teams work collaboratively to drive the production of alphas and financial strategies – the foundation of a balanced, global investment platform.

WorldQuant is built on a culture that pairs academic sensibility with accountability for results. Employees are encouraged to think openly about problems, balancing intellectualism and practicality. Excellent ideas come from anyone, anywhere. Employees are encouraged to challenge conventional thinking and possess an attitude of continuous improvement.

Our goal is to hire the best and the brightest. We value intellectual horsepower first and foremost, and people who demonstrate an outstanding talent. There is no roadmap to future success, so we need people who can help us build it.

The Role:

We are looking for a Quant Developer Intern to join the Book Platform and Operations Teamteam. This is an ideal opportunity for a technically strong student who enjoys solving real problems and wants hands-on exposure to systems that directly support portfolio management operations.

You will work alongside expert developers and portfolio managers, contributing to systems, interfaces, and tools used in day-to-day portfolio management workflows. We value clear thinking, strong fundamentals, and a proactive attitude — we don't expect prior industry experience, but we do expect you to think rigorously and pick things up fast.

Strong performers will be considered for a full-time Quant Developer role upon graduation.

Key Responsibilities:

• Assist in the design, development, and maintenance of systems, interfaces, and tools that support portfolio management workflows, under the guidance of senior developers
• Work with developers and portfolio managers to understand requirements for well-scoped tasks and features
• Help identify, investigate, and resolve issues in existing tools and infrastructure
• Assist with monitoring production systems and support incident response as part of a team
• Participate in code reviews, write tests, and contribute to technical documentation
• Learn and apply modern development tools and practices, including how the team uses LLM-assisted workflows

What You’ll Bring:

Technical

• Currently pursuing a Bachelor's or Master's degree in Computer Science, Engineering, or a related field
• Solid coursework or project experience in Python and/or C++
• Basic familiarity with Bash scripting and Linux environments
• Familiarity with version control systems such as Git
• Strong analytical and logical thinking — you approach problems methodically and don't give up easily
• Meticulous, with genuine care about the quality of your own work
• Proactive and curious — willing to dig into a problem before asking for help, but not afraid to ask good questions
• Able to manage a well-defined task with reasonable independence, with support and guidance readily available
• Ability to learn quickly and adapt to new tools, codebases, and systems
• Effective and concise communicator in English, both written and verbal

Ways of Working

• Comfortable using Claude or other LLM tools as part of your development workflow — for debugging, learning unfamiliar code, and drafting documentation
• Uses LLM tools with judgment — treats them as an aid to thinking, not a substitute for it
• Willing to learn how the team applies LLM-assisted workflows and bring that mindset to your own work

Internship availability - at least 4 months, starting January 2026. Opportunity to convert to a full-time role based on performance.

What We Offer:

• Direct exposure to real portfolio management systems and workflows
• A collaborative team where your contributions are visible and valued
• Opportunity to grow quickly in a technically demanding and intellectually stimulating environment
