Job description

Software Engineering Internship - Summer 2027

Chicago Trading Company (CTC) is a premier proprietary trading firm specializing in options market making. Our collaborative culture fuels innovation in quantitative research, systematic trading strategies, and cutting-edge trading technology. For over three decades CTC has provided critical liquidity across derivatives exchanges worldwide - making them fairer, more transparent, and more efficient.

We strive to be the most innovative firm in the industry today, tomorrow, and long into the future while upholding ethical excellence. We believe that CTC makes a positive impact on the markets, the lives of our employees, and all the communities to which we belong. Started in 1995 by a team of forward-thinking Traders, we are proud to call ourselves an industry leader that keeps making markets and each other better.

The Role

As a Software Engineering (SE) Intern, you will be challenged to learn and adapt in a dynamic, forward-thinking, and fast-paced environment and will experience life as an engineer on one of our technology teams. Your impact is immediate and meaningful. You will work alongside software engineers designing, solving and testing complex coding problems that will deliver solutions to our trading tools and risk applications. You will build the tools traders and quants rely on to price, trade, and manage risk in real time - and because our release cycles are measured in days, you will watch your code reach production and affect the desk almost immediately. This work draws on a solid foundation in computer science, software development practice, and strong communication and teamwork. You will get exposure to the design and implementation of these systems, which will allow you to build upon your technical skills. As part of the Summer Associate cohort, you will learn and socialize alongside other SE Interns and Quant Trading (QT) Interns.

There are a variety of languages you could get practical experience working with including (but not limited to): Java, C++, and Python. Software development cycles at CTC are short, and releases of proprietary software are frequent. This is a fast-paced and dynamic team environment where our engineers quickly see the results of their effort, and the impact that work has on our businesses.

Additionally, our engineers use AI coding assistants and agentic tooling in their daily workflow, and we are actively building AI into our trading, research, and engineering systems. As an intern, you will work in that environment and be encouraged to use these tools to ship more and ship it faster.

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:

• Deliver a technical project in an impactful role mirroring that of a full-time Software Engineering Associate
• Get hands-on experience with our trading technology
• Receive mentorship from members of our technology team
• 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

• A foundation in data structures, object-oriented programming and algorithms, and the ability to apply them to real-world problems
• An interest in learning about technology, trading, pricing and risk management. No prior knowledge or experience in finance is necessary, but a deep curiosity and a hunger to learn is essential
• You are a highly motivated, humble, and collaborative team member
• Ability to thrive in a team-based environment filled with driven people who want to compete and win together
• Ability to effectively communicate ideas both written and verbally that showcase your analytical skills

Key requirements

• You are pursuing a Bachelor’s or Master’s degree in Computer Science, Computer Engineering or a similar technical field with Java, C++, or Python experience
• 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 (most full-time offers will be in Chicago with a limited few in New York, NY)
• 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 forward-thinking 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 $14,500 plus a signing bonus

We recommend focusing on applying for the role that aligns most closely with your skills and interests.

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way.
