Optiver is looking for Quantitative Developer Interns to join our High-Frequency Trading (HFT) team in Austin. Our HFT team is comprised of developers and researchers who design, improve and execute fully automated trading strategies using machine learning. As a Quantitative Developer Intern, you’ll work on complex technical projects, help shape the direction of our trading infrastructure, and work closely with teams to share knowledge and drive technical progress.

Your projects will be scoped based on your team’s real needs — not hypothetical tasks — and your mentor will be fully invested in helping you build high-quality software from scratch that’s designed to last. You’ll contribute to meaningful projects solving trading problems and improving the performance, reliability, and scalability of our systems — and you’ll see your code hit production in real time.

We operate in one of the most fast-paced and competitive environments in the tech industry. That means no two days are the same, and every day brings new, exciting technical challenges to solve.

What you’ll do:

Our internship is designed for fast thinkers with a critical mindset and a drive to solve tough problems. You’ll experience what it’s like to be a full-time engineer at a leading trading firm – working on projects that push the limits of performance, efficiency, and real-world impact. Mentored by Optiver engineers, our program gives you the opportunity to:

• Deep dive into trading fundamentals, from theoretical concepts to financial markets, strategies, and cutting-edge technology.
• Collaborate closely with best-in-class engineers, traders, and business teams to develop, test, and ship your code to production.
• Tackle complex, real-world problems to enhance your critical thinking and problem-solving skills.
• Push your limits and accelerate your growth in a fascinating and high-performing environment.
  
  
  

What you’ll get:

You’ll join a culture of collaboration and excellence, surrounded by curious thinkers and creative problem-solvers. Motivated by a passion for continuous improvement, you’ll thrive in a supportive, high-performing environment alongside talented colleagues, collectively tackling some of the toughest challenges in the financial markets.

In addition, you’ll receive:

• The opportunity to work alongside best-in-class professionals from over 40 different countries
• The opportunity to earn a full-time offer in Chicago, Austin, or New York City based on performance
• A highly competitive internship compensation package
• Optiver-covered flights, living accommodations, and commuting stipends
• Extensive office perks, including breakfast, lunch and snacks, regular social events, clubs, sporting leagues and more
  
  
  

Who you are:

• A student pursuing a bachelor’s, master’s, or PhD in Computer Science or Computer Engineering
• On track to graduate between December 2026 to June 2027, with junior standing or higher
• Passionate for writing clean code, well-architected systems, and continuous improvement
