Overview:

You’ll work on the systems and experiments that shape how we compete on exchanges. This role sits at the intersection of engineering, trading, and market microstructure research – focused on understanding what drives execution outcomes and turning those insights into production systems. 

You’ll collaborate with the team on the mandate is to understand exchange architecture end-to-end – from matching engines and order types to market data feeds and queue dynamics – and use that knowledge to design and evaluate new approaches to order placement and execution. 

Rather than purely optimizing for latency, this role is centered on research, experimentation, and iteration under uncertainty. You’ll explore ambiguous problems where the right answer isn’t known upfront, form hypotheses, and validate them through a combination of data analysis, simulation, and live experimentation. Working closely with researchers, you’ll continuously refine how we interact with markets based on real-world feedback.

Technology at Optiver:

What you’ll do:

• Operate in ambiguous, high-uncertainty environments, turning open-ended questions into a deep understanding of exchange microstructure
• Partner with researchers to design and run experiments that evaluate execution strategies and market behavior
• Build systems that enable rapid iteration on order placement, cancellation, and execution logic
• Translate research findings into robust production improvements
• Own the full loop: idea → experiment → analysis → implementation 

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.
