Susquehanna International Group, LLP

Philadelphia, PA • On-site

Full-time, Temporary, Internship

Re-posted 26 days ago

Job description

Overview
Susquehanna's trading internship provides a distinctive opportunity to learn about quantitative trading. Splitting their day between working on a trading desk and education in a classroom setting, interns receive the best preparation possible for careers in quant trading. During their time on the trading floor, interns will be fully embedded within a trading desk, working side by side with an experienced trader who will serve as a mentor. While in education, interns will receive industry-leading training in options theory and decision science from traders fully dedicated to trader development. Students with a STEM background can leverage their quantitative skills and learn how Susquehanna uses game theory, decision science, and cutting-edge technology to make trading decisions. The goal of the program is to provide interns with a deep exposure to trading, so they can decide if it is what they want to pursue full-time.
What we're looking for
    • Intention to graduate with a minimum of a bachelors degree and begin full time employment by August 2028
    • Exceptional quantitative, logical reasoning, and analytical skills
    • General computer skills required; computer programming skills a plus
    • Demonstrated interest in strategic games and/or competitive activities
    • Ability to thrive in a fast-paced and competitive environment
    • Visa sponsorship is available for this position

What's in it for you:
    • Our non-hierarchical culture allows employees of every level to thrive and make impact. We are not your typical trading firm - the environment is casual, collaborative and we focus on continuous development.
    • 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 forty thousand square-foot state of the art fitness facility with brand-new equipment, multi-purpose courts, group exercise classes, and locker room spaces
    • Discounts for dining, entertainment, shopping, travel, and attractions
    • Social events including a poker tournament, dinners, and sporting events in Philadelphia
    • On-site Wellness Center
    • On-site services such as a mailroom, barber, dry cleaning, and car maintenance
    • Opportunities to give back to the community through Susquehanna sponsored events and donation drives
