Quant Internships information

What is a quant internship?

A Quant Internship is a temporary position where students or recent graduates work with quantitative finance teams at hedge funds, banks, or trading firms. Interns use mathematical models, programming, and statistical analysis to analyze financial markets, develop trading strategies, or enhance risk management techniques. These roles typically require strong skills in programming (Python, C++, or R), statistics, and financial mathematics. The internship provides hands-on experience in algorithmic trading, portfolio optimization, and data-driven decision-making. Successful interns often receive full-time job offers in quantitative finance.

What kinds of projects or tasks are typically assigned to quant interns during their internship?

Quant Interns often work on projects such as data analysis, building or testing quantitative models, conducting backtesting on trading strategies, or supporting research on market trends. Daily tasks may include coding in languages like Python or R, analyzing large datasets, and preparing reports or presentations on findings. Interns typically collaborate closely with senior quantitative analysts, traders, or technologists, and may participate in team meetings or brainstorming sessions. This hands-on experience provides invaluable insight into the workflow of a quant team and helps interns develop practical skills applicable to full-time quantitative roles.

What are the key skills and qualifications needed to thrive in a quant internship, and why are they important?

To thrive in Quant Internships, a strong background in mathematics, statistics, programming (often Python, R, or C++), and familiarity with financial concepts is essential, typically supported by enrollment in a quantitative degree program such as math, physics, engineering, or finance. Interns should be adept with data analysis tools, statistical packages, coding platforms, and may benefit from exposure to Bloomberg terminals or similar financial data systems. Excellent problem-solving abilities, attention to detail, effective communication skills, and the ability to collaborate within teams are key soft skills in this field. Mastering these skills enables interns to contribute meaningfully to quantitative research, model development, and analytical projects within fast-paced financial environments.

Job description

The Role  

As a Quant Trading (QT) Intern, you will be challenged to learn and adapt in an exciting team environment and will play a substantial role in our day-to-day trading and quant-related activities. Your impact is immediate and meaningful. You will become a member of a team for the summer and play a vital role completing project work and/or identifying trading opportunities and communicating with software engineers, quants, traders, and risk managers throughout the trading day. As part of the Summer Associate cohort, you will learn and socialize alongside other QT Interns and Software Engineering (SE) Interns.

What to Expect

The 8-week internship program gives you insight into our culture and an inward look into what our business is all about. You will participate in three classroom learning experiences including: a week-long Basics of Options class, a multi-week class on the fundamentals of market making (Mock Trading), and a multi-week class that introduces elements of our quant framework (Quant Curriculum). You will also attend planned social activities and talks from various business leaders to propel your professional growth, and build your network with CTC employees and fellow interns. You will:

  • Work in an impactful role mirroring that of a full-time Quant Trading Associate (QTA)
  • Get hands-on experience with trading and exposure to our trading technology
  • Have weekly one-on-one meetings with your manager to ensure you are progressing and learning throughout the program
  • Receive mentorship from members of our trading and/or quant teams
  • Experience a culture with a strong emphasis on teamwork and collaboration built through various educational and social activities

What it takes for you to be successful  

  • You have a competitive drive and are a highly motivated individual that only gets stronger as part of a collaborative team
  • You have a desire to work in tandem with traders, quants, developers, and other experts to further CTC's goal of providing world class liquidity to financial markets
  • You love solving complex problems
  • You're intellectually curious and like to challenge the status quo
  • You can effectively communicate sophisticated ideas both written and verbally
  • Strong quantitative and analytical abilities
  • Basic programming skills or a willingness to learn Python
  • No prior experience in finance is necessary, but a deep curiosity and hunger to learn about finance and trading is essential

Key Requirements  

  • You are pursuing a Bachelor's or Master's degree. All majors and concentrations welcome.
  • You will graduate between December 2027-June 2028
  • You have a demonstrated record of success (academics, awards, etc.)
  • You are willing to relocate to Chicago, IL for the summer (with full-time placement in Chicago)
  • You can participate in the full duration of the 8-week program from mid-June to early August 2027

Why should you consider interning at CTC?

  • Be part of a fast-growing, industry-leading global trading company
  • Work in an environment that actively explores and applies emerging technologies - including AI - to enhance trading, engineering, and research workflows
  • Opportunity to work with and learn from leaders in our industry
  • Excellent support system to ensure your learning and development
  • Competitive pay, free housing with your fellow interns in downtown Chicago, and free breakfast, lunch, and snacks!

Compensation

Monthly salary of $16,500 plus a signing bonus

Please note: You are allowed to submit one application per position (i.e. SE Intern and QT Intern) during the recruiting cycle. We recommend focusing on applying for the role that aligns most closely with your skills and interests. While you can apply for more than one role, please keep in mind that each application will be assessed according to the specific requirements set for that role.
