We are seeking a highly analytical and technically strong Trader with deep expertise in prediction markets and real-time modeling. The ideal candidate combines strong trading intuition, robust statistical and programming skills, and the ability to translate ambiguous problems into structured, high-quality models that drive profitable decision-making.

Key Responsibilities

• Design and develop complex models to generate real-time fair values for intricate, uncertain domains (e.g., weather, event-driven outcomes, or probabilistic systems)
• Identify edge cases, structural pitfalls, and modeling risks, proactively addressing them to ensure robustness and operational stability
• Assess data needs and sourcing strategies, determining what inputs are required for accurate forecasting and collaborating with relevant teams to acquire them
• Build initial model prototypes in Python, using libraries such as pandas and numpy, and partner closely with developers to productionize these models for real-world trading
• Monitor, validate, and iterate on production models, ensuring strong performance and continuously improving predictive accuracy and trading outcomes
• Identify, evaluate, and execute market-take opportunities arising from model insights and prediction-market dynamics
• Collaborate with engineering teams to optimize trading strategies, enhance infrastructure, and scale automated decision-making

• Strong understanding of trading concepts, decision science, and probabilistic reasoning
• Extensive experience with prediction markets, including market structure, pricing mechanics, and liquidity dynamics
• Proficiency in Python, with deep working knowledge of pandas and numpy
• Ability to think critically about uncertainty, model assumptions, and real-world edge cases
• Strong communication skills and the ability to work cross-functionally with traders, developers, and data teams

What’s In It For You

• Relaxed dress code (jeans and sneakers are the norm and team jerseys every Friday)
• Fully stocked kitchens for breakfast, lunch, snacks, and beverages
• A 40,000 square-foot state of the art fitness facility with brand-new equipment, multi-purpose courts, group exercise classes, and locker room spaces
• Discounts for dining, entertainment, shopping, travel, and attractions
