Help make the world more hospitable

The hospitality industry is uniquely human, and it deserves technology that’s just as inspiring as the people behind it. At Mews, we’re transforming the industry with a platform that helps hotels run smarter, move faster and create better guest experiences.

You’ll work with smart, curious people who care deeply about what they do. You’ll have autonomy and the trust to make good decisions and move quickly. And you’ll enjoy a real sense of purpose as you see the impact of what we’re building.

If you’re motivated by ownership, curiosity and meaningful impact, and are driven to deliver consistent high performance, you’ll feel at home here.

About the role

Let's get into the specifics. It’s impossible to capture every nuance of a role – especially at a rapidly growing company like Mews – but if we had to distil it into a job description (which we do because this is a job description), it would be this:

This role sits inside the FinCrime team at Mews Fintech, working at the intersection of fraud operations, data, and product. You will use data to improve how transaction monitoring works — finding the gaps in detection rules, reducing false positives, and helping the team focus its attention on the cases that actually matter. This is not a reporting role. The expectation is that you move from investigation to action: spot what is going wrong, understand why, and recommend practical changes that improve outcomes.

You will work with SQL and Python across large datasets, partnering with FinCrime, Product, Compliance, and Data teams to improve controls, bring in new data sources, and support the development of internal scoring approaches and future machine learning use cases. The environment is fast-moving and not everything is perfectly defined — that is part of what makes the work interesting, and the right person will be energised by that rather than slowed by it.

What you would do

Review transaction monitoring and fraud rule performance to identify gaps, inefficiencies, and opportunities to improve detection
Investigate trends, anomalies, and behavioural patterns across transactions, properties, and customer activity
Improve how cases are prioritised by risk, reducing manual review volumes and increasing focus on high-risk activity
Partner with FinCrime, Product, Compliance, and Data teams to improve controls and bring in new data sources
Work with data engineers to support better pipelines, data quality checks, and more reliable monitoring inputs
Support the development of internal scoring approaches and future machine learning use cases as the function evolves
Translate complex findings into clear recommendations that improve fraud prevention while minimising friction for legitimate customers

What you would bring

Strong experience in fraud detection or transaction monitoring, with a track record of improving rules, controls, or detection approaches using data — not just describing what the data shows
Advanced SQL skills and strong Python skills, with experience working across large datasets to identify patterns, outliers, and risk signals
The ability to move from investigation to action: you do not stop at findings, you follow through to recommendations and work with stakeholders to implement them
Comfort working cross-functionally with operational, technical, and compliance stakeholders
You have integrated AI into how you work — using it consistently to get to conclusions faster, check your thinking, and improve the quality of your output
Background in fintech, payments, buy now pay later, e-commerce, or transaction monitoring and fraud solution providers is strongly preferred

Life at Mews

We’re an equal opportunities employer. We value teams that reflect the diversity of the customers and communities we serve. Different perspectives make better ideas, stronger products and a more welcoming company.

We also believe transparency is important when deciding if you're the right fit. Mews is an ambitious, high-pressure environment of continuous learning and high standards. Success here requires resilience, adaptability and a willingness to solve difficult problems.

A few things that define how we work:

High autonomy means high responsibility. People are expected to take ownership and drive outcomes. There isn’t a detailed playbook for everything, and that’s part of what makes the work challenging – and rewarding.
Change is constant. We’re growing quickly and adapting as we scale. Teams, processes and priorities continue to evolve, and only people who stay curious and agile will thrive.
We’re remote-first, not relationship-free. Flexibility is core to how we work, but strong relationships still matter. Our teams are global, so we need expert collaborators and communicators to help us move forward together.
AI is an integral part of our processes. It’s not here to steal people’s jobs, but to amplify efficiency and productivity. We’re motivated to proactively use the technology to seek out better ways of working and share our findings with the rest of the company.

If there's anything we can do to support you during the application process, let us know.

We don't discriminate on the basis of race, religion, colour, nationality, gender, sexual orientation, age, marital status, veteran status, disability or any other protected characteristic.

One final thing: don't hold back. If you don't meet 100% of the criteria in this job description but you're certain you could make a big impact, apply. Everyone should have equal access to opportunities, and we're committed to providing an inclusive experience.

If Mews sounds like the kind of environment where you'd thrive, we'd love to hear from you.
