Belvedere Trading is a leading proprietary trading firm proudly headquartered in downtown Chicago. 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. This wouldn’t be possible without the dedicated efforts of our technology teams who utilize and perfect our innovative technology 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 look for passionate team members that excel and their contribution is critical to our continued success. The Data Platform team delivers high-quality data solutions to our core trading and affiliated teams. We support end users who rely on data for analytics and research, as well as those who depend on the database infrastructure backing production trading systems. Our mission is to ensure that well-curated, trustworthy data is available to the right people at the right time, along with the tools needed to perform complex analytics and make data-driven decisions. The Data Integrity Engineer is responsible for ensuring that Belvedere’s data is accurate, consistent, and reliable across systems and over time. This role designs, implements, and maintains data pipelines and validation processes, including checks for completeness, consistency, and quality. The engineer monitors key datasets and dashboards, investigates anomalies, and partners with data engineers, quants, analysts, and business stakeholders to resolve root causes and prevent recurrence. They define and document data standards, business rules, and lineage so teams can confidently use data for reporting, analytics, and decision-making. This is a hands-on role working with SQL, Python and modern data platforms, and is critical to building trust in Belvedere’s data. A passion for supporting data consumers and development teams, strong attention to detail, and genuine curiosity about data are essential. You will be expected to quickly build industry knowledge and technical skills, dive into complex problems, adapt to evolving technologies and business requirements, and actively contribute your insights to enhance team outcomes.
