Senior Quantitative Developer

DRW is a diversified trading firm with over 3 decades of experience bringing sophisticated technology and exceptional people together to operate in markets around the world. We value autonomy and the ability to quickly pivot to capture opportunities, so we operate using our own capital and trading at our own risk.

Headquartered in Chicago with offices throughout the U.S., Canada, Europe, and Asia, we trade a variety of asset classes including Fixed Income, ETFs, Equities, FX, Commodities and Energy across all major global markets. We have also leveraged our expertise and technology to expand into three non-traditional strategies: real estate, venture capital and cryptoassets.

We operate with respect, curiosity and open minds. The people who thrive here share our belief that it’s not just what we do that matters–it's how we do it. DRW is a place of high expectations, integrity, innovation and a willingness to challenge consensus.

We are seeking a Senior Quantitative Developer / Senior Software Engineer to design, build, and operate state-of-the-art infrastructure for mid-frequency equity statistical arbitrage strategies. This role requires hands-on ownership of production trading systems across the full systematic trading stack, from data ingestion through execution and real-time monitoring.

The successful candidate is expected to contribute meaningfully from day one and does not require training on core systematic trading concepts or infrastructure.

• Build and optimize large-scale data pipelines for market, fundamental, and alternative datasets
• Develop and maintain research and back testing platforms with realistic transaction cost, execution, and constraint modeling
• Integrate strategies with execution systems and order management, and support real-time trading and monitoring
• Ensure production systems are performant, reliable, observable, and operationally robust
• Build tooling for diagnostics, performance attribution, and post-trade analysis
• Continuously improve system design, scalability, and operational resilience.

Requirements

• 5+ years of hands-on experience in a hedge fund, proprietary trading firm, or sell-side trading or electronic execution team, with direct responsibility for production trading infrastructure
• Proven experience designing, building, and operating live trading systems
• Excellent logical reasoning, strong quantitative and analytical skills
• Clear understanding of the end-to-end equity systematic trading stack, including:
  • Data ingestion, validation, and normalization
  • Backtesting and simulation
  • Portfolio construction and constraint enforcement
  • Execution integration and live trading support
• Strong engineering discipline and ability to work independently with minimal guidance.
• Meticulous attention to details and accuracy in work
• Excellent verbal and written communication skills, with the ability to effectively interact with the global team
• Ability to adapt in a fast-paced, collaborative, and results-oriented environment, and thrive under time-sensitive and high-pressure situations
