Senior Trading Software Engineer

JavaC++ Hybrid

Belvedere Trading is a leading proprietary trading firm with offices in Chicago, New York, Boulder, and Singapore. Our traders work hard to provide liquidity to the market through their market-making activities and are the masters of a diverse set of commodities, interest rates, exchange-traded funds (ETF), and equity index options. From the beginning, we began iteratively investing in our proprietary technology and committing to building our systems from the ground up. Our trading models and software systems are continually re-engineered, optimized, and maintained to stay on top of the industry. We operate best within a team environment where we challenge each other to deliver value consistently and share in the success of the company.

We’re looking for a Senior Trading Software Engineer to help push the boundaries of our trading platform. You’ll work side-by-side with traders and quantitative researchers to design and evolve the infrastructure behind our automated options trading systems. Our core platform is built in Java, but we’re expanding into modern C++ to drive our strategies into new markets. This role will have a hand in everything from trading logic to system performance to FPGA integrations. We operate every day with rigorous code reviews, automated testing, and scalable best practices. If you love optimizing every microsecond, solving real-time problems, and building scalable, battle-tested systems, this role will keep you challenged and engaged every day.
