Overview:

You’ll work directly with traders to solve the core problems that drive our trading. This role is fully embedded on the desk, owning systems and workflows end-to-end across the stack—from real-time trading infrastructure to internal tools and analytics. 

Unlike more specialized roles, you’ll operate across a wide range of challenges: building new trading logic, improving existing systems, developing tools to support decision-making, and scaling infrastructure as strategies evolve. The problems are fast-moving and often ambiguous, requiring close collaboration with traders and a strong sense of ownership. 

This is a high-impact role where your work directly influences trading performance, and where success comes from quickly understanding problems, building solutions, and iterating in production.

Technology at Optiver:

At Optiver we pride ourselves on being real engineers, not just coders. Our engineers work closely with traders to identify the business problems we face and determine how they should be solved. We apply a disciplined and scientific approach. We engineer simple, well-architected solutions that meet the dynamic needs of our traders. Our passion is to solve problems which really matter to the business, and we take pride in the quality of our solutions.

What you’ll do:

• Work side-by-side with traders to identify, prioritize, and solve high-impact problems
• Build and maintain systems across the stack, including trading logic, infrastructure, and internal tooling
• Rapidly prototype and iterate on solutions based on live feedback from the desk
• Take ownership of problems end-to-end: idea → design → implementation → production → iteration
• Operate effectively in a fast-paced, ambiguous environment where priorities evolve quickly 

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:
