The Role

Brownstone is seeking a quantitative trader to own P&L in an automated pricing and market-making business in fixed income. This is a trading seat first where the candidate is expected to run a live book and is accountable for its returns. You will find unique market structure inefficiencies, liquidity fragmentation across venues and protocols, routing and execution gaps, and build a trading strategy that profits off that.

Responsibilities

• Own P&L in an assigned product or strategy, including inventory, risk, and return on balance sheet
• Run automated pricing and execution across client inquiry, streaming, and venues
• Design, backtest, and deploy systematic pricing, execution, and market-making models and iterate on them with live data
• Partner with technology to advance the firm's electronic trading platform and infrastructure
• Contribute quantitative and market insight to the broader floor

Qualifications

• Bachelor's or advanced degree in a quantitative field (mathematics, statistics, computer science, engineering, or similar)
• 5+ years running systematic pricing, electronic market-making, or algorithmic execution in a live book
• Strong programming and system design skills; experience building asynchronous services for pricing, order routing, and execution
• Fluency with modern AI tools, including LLM-assisted coding and research workflows
• Demonstrated knowledge of market microstructure and experience managing P&L and risk

Why Brownstone

• Distribution across 2,200+ counterparties feeding a rapidly scaling e-trading business
• Balance sheet and risk limits sized to the opportunity
• Direct partnership with technology and an extremely flat, entrepreneurial structure
• The chance to build a business
