Senior Backend Engineer - Spend Fraud Team

Wise is one the fastest growing companies in Europe and we’re on a mission: to make money without borders the new normal. We’ve got 15 million customers across the globe and we’re growing. Fast.

Current banking systems don't let us send, spend or receive money across borders 

easily. Or quickly. Or cheaply. 

So, we’re building a new one.

And, we need a Senior Backend Engineer to join our mission and help us build a global platform that’s scalable, reliable and secure. We’re building experiences allowing international businesses to send their money conveniently and reliably.

The Team you will be working with: Spend Fraud

The mission of the Spend Fraud & Disputes Team is to support crime-free card usage, with a minimal impact on customers' spending experience, and provide customers with a convenient way to resolve their disputes.

As a software engineer you will be working with modern technologies to build a strong protection against fraudsters for our customers. Machine learning (coming soon), high-throughput and processing big sets of data are parts of our daily life. 

You will be involved in different aspects of integration with VISA, Mastercard and other schemas and work on it to help our customers resolve disputes in the most convenient way. 

A lot of your tasks require working closely with product and operational teams. Instant feedback loop and effective communication will help you create a product that is tailored to your audience. 

The fraudsters will make sure you'll never be bored!

What does it take?

• A product mindset and passion for user experience. You want to prioritise work with customers in mind and can make data-driven decisions to fix customer pain-points
• Great communication skills and the ability to articulate complex, technical concepts to any audience, even a non-technical one
• Experience with any of OOP languages like Java, Kotlin, C# and others
• Experience working with relational databases, query optimisation and schema design. Ideally, you’ll also have some experience with a few non-relational databases
• Reliance on automated tests and observability tooling to increase confidence building and maintaining services
• Experience with distributed systems - you know a thing or two about microservices, messaging systems like Kafka and how to design software with their possibilities and constraints in mind
• You have tried different software development methodologies and have found that there is no silver bullet - you prefer to think deeply about a problem and then decide on what structure and patterns to use to solve it.
• Ability to work independently while also being a good team player. Your work will frequently involve cross-team collaboration.
• Ability to break down complex projects into incremental milestones that deliver customer value
• Experience with common design and architectural patterns coupled with a passion for writing clean code that is performant and well tested 
• Curiosity and drive for continuous learning and improvement
• Following and advocating best coding practices, continuous delivery and code reviews

…but don’t worry we don’t expect you to know everything!

• 🚀 RSU's in a growing company 
• 💪 An annual self-development budget

Also, qualifications aren’t that important to us. If you’ve got great experience, and you’re great at articulating your thinking, we’d like to hear from you.
