Senior Fraud Analyst
Senior Fraud Analyst is a senior analyst who detects fraud on the platform, including multi-accounting, bonus abuse, match fixing and payment schemes, and develops protection rules.
What a Senior Fraud Analyst does
The Senior Fraud Analyst makes sure a sportsbook platform does not lose money to fraudulent schemes. In betting, this means bonus abuse, networks of accounts controlled by one person, manipulation of withdrawals, bets placed with insider information, and attempts to launder money through betting. Companies in this vertical need this role because a bookmaker's margin depends on precise protection: one organized abuse of a promo campaign can wipe out a whole month's budget.
The role sits within the risk function or the anti-fraud team. The Senior usually reports to the Head of Fraud or Head of Risk and works closely with risk managers, odds trading, the payments team, customer support and CRM. The Senior does not manually review every account. Instead, they investigate complex cases, write rules for automated checks and assign tasks to junior analysts.
A typical week includes working through the alert queue, investigating groups of linked accounts, analyzing a new scheme flagged by support or traders, and agreeing rule changes with the product team. Results are measured not by the number of closed cases but by how much money is saved and how few legitimate players are affected by blocks.
Responsibilities
- Investigate complex multi-accounting and bonus abuse cases, including linked account groups, shared devices and payment details
- Identify signs of match fixing and insider betting by comparing player behavior with odds movements and bet timing
- Develop and calibrate anti-fraud rules and scoring models together with risk management
- Analyze failed and disputed automated decisions, find the causes of false positives and propose adjustments
- Monitor payouts and withdrawals for schemes involving deposits and withdrawals without any gameplay activity
- Maintain a database of fraud patterns and update it regularly based on investigation results
- Prepare analytical memos for management with conclusions, loss estimates and recommendations
- Take part in reviews requested by payment partners, banks and regulators, preparing evidence
- Train and supervise junior analysts and check the quality of their conclusions
- Coordinate blocks and restrictions with CRM and support to avoid harming loyal customers
Skills
- Building hypotheses about fraud schemes and testing them on data
- Working with large samples of behavioral data: sessions, bets, deposits and withdrawals
- Understanding betting mechanics, lines, margins and bonus mechanics
- Balancing losses from fraud against losses from wrongly blocking legitimate players
- Writing rules and automation requirements in clear language for developers
- Presenting findings to non-technical executives and external partners
- Running investigations while preserving an evidence trail and documenting decisions
- Mentoring junior analysts and reviewing their analytical conclusions
- Knowledge of KYC and AML principles and regulatory monitoring requirements, without tying them to specific rules
Tools
- SQL for queries on bets, sessions and payments
- BI systems (Metabase, Looker, Tableau) for dashboards and monitoring
- Anti-fraud systems and scoring engines, both internal and vendor-built
- Python or R for analyzing data exports and finding links between accounts
- Jira or Confluence for task queues and a knowledge base of schemes
- Google Sheets or Excel for quick calculations and reconciliations
- Graph tools for visualizing connections between accounts
How performance is measured
- Share of fraudulent accounts detected before funds are withdrawn
- Dynamics of fraud and bonus abuse losses prevented over time
- Share of rules and blocks that are false positives affecting legitimate players
- Response time to a new attack pattern, from the first signal to a rule
- Share of investigations closed with a final decision within the agreed timeframe
- Quality of conclusions as assessed by a manager or QA
By vertical
Betting
In betting, the main schemes are bonus abuse on free bets and promotions, match fixing, insider betting and odds arbitrage, as well as laundering through bets on low-liquidity events. The analyst works closely with odds trading and risk management on bet voids, limits and market closures.
Levels
Senior
The Senior independently handles complex cases, shapes the anti-fraud strategy for the product, agrees rules with risk management and product teams, trains juniors, and presents findings to management, as well as when interacting with payment partners and regulators.
How to get there
People often enter the profession from adjacent roles: data analyst, analyst in a risk team, or a security or support specialist who has worked through disputed cases. A candidate's strength is the ability to work with SQL, spot patterns in user behavior and write conclusions that are clear to non-analysts as well.
To prepare, it is useful to learn betting and bonus mechanics, understand KYC and AML processes, and practice forming hypotheses about schemes and testing them on data. Practice on real cases matters more than theory-only courses: try analyzing public descriptions of schemes, building a simple model of connections between accounts, and formulating a rule.
Growth goes from a junior who clears standard alerts, to a mid-level analyst who runs investigations independently, and then to a senior who owns strategy and rules. The move usually comes with the ability to explain decisions to management and to mentor within the team.

FAQ
How is a Senior Fraud Analyst different from a regular anti-fraud analyst?
A regular analyst mainly works through the alert queue and checks individual accounts against existing rules. A Senior takes on complex group schemes, writes and calibrates rules, is responsible for conclusions presented to management, and trains the team. The responsibility shifts from execution to strategy.
Do you need to know how to program?
For most positions, confident SQL and an understanding of how to read data are enough. Python or R help with analyzing links between accounts and processing large exports, but the ability to formulate hypotheses and test them is valued most.
What experience is needed to get this role?
Candidates are usually expected to have experience working with behavioral data or investigations in risk, analytics, security or support. It is important to show investigations you conducted independently and rules you wrote or improved.
What determines income in this role?
Pay depends on the size and type of company, the maturity of the risk function, the depth of responsibility for rules and losses, as well as location and whether management duties are included. Experience in betting or adjacent verticals, where schemes are more complex, is usually valued more highly.
Which matters more: analytical skills or industry knowledge?
Both matter, but without an understanding of betting mechanics, bonuses and payment flows, an analyst quickly runs into a lack of context. Analytical skills help uncover schemes, while industry knowledge helps determine which of them are actually dangerous.
How do you balance protecting the business with keeping players happy?
The Senior constantly weighs losses from fraud against losses from wrongful blocks. Where there are doubts, they propose restrictions instead of full account closures and coordinate decisions with CRM and support so that legitimate players do not leave because of false suspicions.
