Quantitative Researcher Internship (Dec 2025)

As our Quantitative Research Intern, you’ll spend your summer delving into complex, data-driven problems at one of the world’s leading tech-driven trading firms. Under the guidance and mentorship of industry experts, you’ll apply your critical mindset and strong technical skills to optimise the models that drive Optiver’s innovative trading strategies.

Through a mix of trading lectures, coursework and hands-on project experience, you’ll have deepened your understanding of the quantitative trading industry and mastered the practical skills needed to drive our trading success by the end of the 8-week internship. Plus, if you’ve excelled over the summer, you’ll receive an offer to return as a Graduate Quantitative Researcher.

What you’ll do

Led by our in-house education team that consists of ex-traders and engineers, you will complete a curated series of lectures and coursework on trading fundamentals, covering topics such as options pricing, financial markets, trading strategies and cutting-edge technology.

Then, you will join one of our research teams and be paired with a mentor, applying your recently acquired knowledge to real-world scenarios that contribute towards our trading success. Some of the topics you could be working on, include:

• Using statistical models and machine learning to develop trading algorithms.
• Leveraging big data technologies to analyse high-frequency trading strategies, market microstructure, and financial instruments to identify trading opportunities.
• Building stochastic models to determine the fair value of financial derivatives.
