Job description

Overview

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.

What You'll Do

• 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.

What We're Looking For

• 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 We Offer

• Relaxed dress code (jeans and sneakers are the norm and team jerseys every Friday).
• Fully stocked kitchens for breakfast, lunch, snacks, and beverages.
• A 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.
• Social events such as a poker tournament, holiday party, company outings, and more.
• On‑site services such as a wellness center mailroom, barber, dry cleaning, and car maintenance.
• Opportunities to give back to the community through Susquehanna sponsored events and donation drives.
