Vacatures developer

• You'll see the engineering decisions you make - about data shape, replay performance, external coverage - land directly in what kinds of research the firm attempts next;
• You'll work closely with traders, researchers and platform teams to build and run the pricing data systems the firm trades and prices off - both live and across many years of history;
• PDG owns the production pipelines that compute and serve our core pricing data. This includes:
• Build and optimize live pricing systems that run continuously throughout the trading day
• Develop replay frameworks that reproduce production pricing calculations over years of historical market data
• Integrate new external datasets into Optiver's pricing ecosystem to expand research capabilities

You'll join a small, multidisciplinary group that ships across the C++/Python boundary daily, with a direct line to the trading and research consumers of your work;

• Strong engineering instincts and a solid grounding in computer-science fundamentals;
• Productive in either C++ or Python, comfortable working in the other, and able to move fluidly between systems-level code and orchestration / ETL code;
• Comfortable designing distributed data systems and understanding trade-offs around throughput, schema evolution and historical replay;
• Experience with data platforms (e.g. Delta Lake), cloud infrastructure or large-scale data engineering is a plus;
• Pragmatic about delivery: able to spot the "good enough" path through a complex domain while keeping a clear-eyed view of where the right long-term investment is;
• Operational mindset - you reach for monitoring, validation, and data-quality checks instinctively rather than treating them as someone else's problem;
• A collaborator who can work with traders, researchers, and other engineering teams to turn ambiguous requirements into production systems;
• Interest in systematic trading, derivatives pricing, or quantitative finance more broadly is a strong plus - but not a hard requirement; we will teach you what you need to know.
