Software Engineering Internship: Summer 2026
Overview
Susquehanna is looking for highly motivated full-time students for our 10-week software engineering summer internship program. As a software engineering intern, you’ll be part of a team that builds some of the most powerful trading systems in the finance industry. You will work alongside our experienced software engineers on the development, delivery, support, and enhancements of our trading systems and infrastructure.
Throughout the summer, you will have the chance to work on challenging projects that will be pushed into production. You’ll also meet with senior technologists to learn about Susquehanna technology and how it impacts our trading strategies.
To learn more about what it’s like to work at Susquehanna, check out our campus programs site, where you can take a virtual office tour, meet some of our employees, and learn more about our unique culture!
We will begin the recruiting process for this role in August.
What we’re looking for

- Intention to graduate with a minimum of a bachelor’s degree and begin full time employment by August 2027
- Strong software development skills in any object oriented language (we use C++, Python, and C# the most)
- Knowledge of algorithms, data structures, and object-oriented design patterns
- A passion for technology and a tinkering spirit
- Exceptional problem solving skills
This internship will be a fully in-person experience in our Philadelphia-area headquarters.
What's in it for you:

- Housing provided for duration of internship
- Relaxed dress code: jeans and sneakers are the norm, shorts all summer long
- Fully stocked kitchens for breakfast, lunch, snacks, and beverages
- A 40,000 square-foot state of the art fitness facility with brand-new equipment, multi-purpose courts, group exercise classes, and locker room spaces
