Senior Software Engineer – Execution Systems

Belvedere Trading is a leading proprietary trading firm proudly headquartered in downtown Chicago, with a satellite office in Boulder, Colorado. Our teams work hard to provide liquidity to the market through their market-making activities by combining their deep expertise in commodities, interest rates, exchange-traded funds (ETFs), and equity index options with a cutting-edge technological system. Our trading models and software systems are continually developed, optimized, and upgraded in order to stay competitive in an ever-changing market. We work closely with our technology team to continuously and iteratively improve our proprietary solutions. 

High-performance proprietary development is the source of our success and competitive advantage at Belvedere, further fueling our passion for performance. We are a team driven by intellectual curiosity, seeking answers that will change not only how we trade in this technological age, but also the future landscape of the trading industry. We place a high premium on defining, developing, and deploying high-performance trading software using a team-based, holistic development approach. We are looking for passionate team members whose contributions will be critical to our continued success.

The Combine Execution team is responsible for transforming quantitative models into live trading decisions with sub-microsecond precision at global scale. 

We are a distinct group within Belvedere, reimagining what a modern trading system looks like from the ground up. Our systems deploy multithreaded C applications to exchange collocated datacenters and integrate tightly with cloud-based modeling services. We operate under strict latency constraints, ranging from microsecond to sub-microsecond, while maintaining scalability and resilience across global markets. 

Our team is based in both the Chicago and Boulder offices, with a hybrid work model that balances in-office and remote collaboration.
