Core Responsibilities

Primary Functions

Conduct rigorous, repeatable pre-match and in-play analysis to identify long-term positive expected value (EV) opportunities across sports, casino games, and alternative gaming markets using historical data, real-time feeds, and proprietary models.
Design, build, and maintain statistical and machine learning models that predict game outcomes, player performance, or market movements to generate actionable bet signals and improve decision-making accuracy.
Execute stakes and trades across multiple bookmakers, exchanges, and proprietary platforms, ensuring optimal timing, liquidity management, and minimum market impact while capturing price inefficiencies.
Implement disciplined bankroll management policies and staking strategies (Kelly criterion, fixed fraction, or custom portfolio methods), monitoring drawdowns and adjusting risk parameters to preserve capital and maximize long-term growth.
Continuously monitor odds movement, line changes, and market-shaping events to detect arbitrage, middles, and correlated exposures while coordinating hedges when appropriate to lock in profit or reduce undesirable risk.
Perform post-event analysis and performance attribution that quantifies ROI, edge, variance, and model decay; iterate models and strategies based on rigorous backtesting and out-of-sample validation.
Maintain comprehensive logs and trade journals documenting rationale, expected value, stake size, execution details, and lessons learned for each wager or trade to support accountability and continuous improvement.
Integrate and normalize disparate data sources (historical results, player stats, weather, injury reports, bookmaker odds, live feeds) into consolidated pipelines to support rapid strategy deployment and research.
Develop automated scouting and signal-alert systems that flag high-probability opportunities and notify stakeholders or trigger automated execution while maintaining guardrails against model drift.
Collaborate with pricing teams, risk managers, and platform engineers to share market intelligence, align on limits, and calibrate exposure across correlated events or markets to protect capital and maintain stable operations.
Manage daily liquidity and counterparty relationships with exchanges, bookmakers, and liquidity providers to ensure execution capacity, favorable limits, and manage credit or settlement risk.
Evaluate and implement trading automation tools, bots, and APIs with robust controls, signal validation, and fail-safes to scale execution while minimizing operational and technical risk.
Apply advanced probability, Bayesian updating, and game theory concepts to refine forecasts and quantify uncertainty, ensuring more robust decision rules under partial information and noisy signals.
Maintain strict adherence to all legal, regulatory, and platform-specific rules and anti-fraud measures to avoid sanctions, account closures, or reputational risk while ensuring KYC/AML compliance where relevant.
Conduct competitor and bookmaker profiling to identify behavioural patterns, limit thresholds, and market inefficiencies, then adapt tactics to exploit weaknesses while rotating markets to avoid account limitation.
Design and run controlled experiments (A/B tests) on staking approaches, market timing strategies, and model parameters to statistically validate improvements before full-scale deployment.
Train, mentor, or supervise junior bettors, traders, or research analysts, transferring systematic processes for model development, trade execution, risk controls, and performance review.
Create and deliver concise performance reports and market briefings to stakeholders, investors, or proprietary firm leadership that summarize P&L, risk metrics, key drivers, and planned adjustments.
Rapidly synthesize breaking news, injuries, lineup changes, and external factors into updated probability assessments and execution decisions, prioritizing stories that materially alter expected value.
Ensure robust operational processes such as session controls, reconciliation of settled bets/trades, and incident response for platform outages, data feed failures, or contested settlements.
Manage tax documentation, record-keeping, and revenue recognition processes in coordination with finance or external accountants to ensure accurate reporting and legal compliance.
Continuously monitor psychological fitness and decision quality under variance, implementing cooling-off rules, mandatory breaks, and pre-commitment strategies to minimize tilt and emotional decision-making.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis.
Contribute to the organization's data strategy and roadmap.
Collaborate with business units to translate data needs into engineering requirements.
Participate in sprint planning and agile ceremonies within the data engineering team.
Assist product and compliance teams with insights on user behavior, suspicious activity patterns, and limit-setting recommendations.
Participate in community knowledge-sharing activities, conferences, and competitive analysis to keep strategies and tools cutting-edge.
