Blockchain and Fraud Models Analyst

Job Description

Trust unlocks our greatest potential.

For decades, the clearing of payments remained unchanged and unchallenged. We asked, what if there was a better way? What if we could make banking infrastructure faster, safer, more reliable, and easier to access for all? Here is where you can think radically and responsibly to find the best solution.

What happens when you know you’re inherently trusted? Trust creates safety. Safety encourages you to be brave, to challenge, to fail, to try new things and to execute. At ClearBank everything revolves around trust. We’re not expected to earn it, but we are expected not to break it. We’re trusted to own it. To solve issues in the moment. To know a good risk when we see one, and the judgement to know that ‘can’ doesn’t always mean you ‘should’.

What you can expect:

ClearBank is a place where you can do things differently and challenge the status quo. We will give you a high level of autonomy and transparency, and we trust you to make the right decisions for the bank.

If that excites you, how about joining our Financial Crimes Operations Models Management team as a Blockchain & Fraud Models Analyst? Reporting to the Models Management Senior Manager, you will specialise in developing and maintaining the monitoring controls of blockchain-based products and screening fraudulent payments.

Your role includes:

• Design, develop, tune and maintain rules and models for blockchain transaction monitoring and fraudulent payment screening, ensuring strong risk coverage and operational efficiency, to support new products and clients

• Analyse blockchain and payment transaction behaviour to identify emerging financial crime typologies, including cross‑chain activity, high‑risk wallet exposure and transaction velocity risks

• Optimise monitoring performance by working closely with data scientists, engineers and compliance teams, enhancing rule logic, thresholds and outputs

• Own the ongoing effectiveness monitoring of rules and models, including rule health metrics, dashboards and regular performance reporting

• Conduct root cause analysis on monitoring incidents and model performance issues, recommending and implementing data‑driven improvements

• Partner with 1st and 2nd Line of Defence teams and external vendors to ensure monitoring controls are well‑calibrated, documented and aligned to risk appetite

• Contribute to strategic initiatives that enhance the organisation’s financial crime analytics capabilities, particularly across blockchain and innovative payment products

What you’ll bring:

To excel in this role, you’ll also need:

• Strong subject‑matter expertise in fraud and blockchain monitoring, including rules, typologies, detection approaches and vendor tooling

• A solid understanding of blockchain use cases and risks, such as digital asset trading, stablecoins, mixers and evasion techniques

• Experience designing and tuning transaction monitoring or fraud rules to balance effectiveness and efficiency

• Knowledge of banking payment products and their fraud risk profiles (e.g. transfers, cards, mobile and app‑based payments)

• Strong analytical capability, with high attention to detail and the ability to interpret data to distinguish normal versus abnormal behaviour

• Confidence communicating complex monitoring approaches and findings to non‑technical stakeholders across technology and business teams

• A proactive, curious mindset with the ability to identify data quality issues and continuously improve financial crime controls

Regretfully we are not able to sponsor applicants for immigration purposes at the current time.

What makes a great ClearBank team member? Does this sound like you?

• You focus on solutions and positive outcomes, thinking radically and responsibly to find the best result for our customers, your colleagues and the bank;

• You actively seek feedback from others to drive your growth and development, always assuming positive intent from others and develop strong, trusting relationships you’re your colleagues and customers: you really, genuinely care;

• You always strive for the highest quality, but you know that done is better than perfect; you welcome a challenge knowing that they learn as you go and iterate;

• ‘I’ before ’we’, isn’t in your vocabulary

If this sounds like you then we encourage you to dust off that CV and apply!

What we offer in return:

• We're flexible – We support a culture of flexibility which allows our employees to achieve a strong work-life balance.

• Offices – Work in a way that works for you – whether that’s in the London office, at home, or hybrid.

• Holiday – 27 days of annual leave per year, plus bank holidays.

• Holiday buy/sell - Buy or sell up to five days of annual leave each year and shape your year around what matters most.

• Work abroad – You have the flexibility to work outside of the UK for up to 30 days in a rolling 12-month period.

• Holiday swap – Option to swap your bank holidays to any other day of your choice.

• Wellbeing – 24/7 employee assistance programme including mental health support, life assurance and income protection.

• Bigger than ClearBank – Take a couple of days per year to do something that matters to you.

• Healthy living – Private healthcare and discounted dental cover, with employee perks and discounts.

• Family – Enhanced family-friendly leave.

• Personal development – We offer personal development budgets, opportunities to take part in role-related training and unlimited LinkedIn Learning.
