Job Description
About the role: We are looking for a talented Senior Software Engineer to join our Payin Platform team in the London office. This team owns layer that powers how money enters Wise. The platform sits between our product teams (Transfer, Acquiring Payment, and any new product that needs to take money in) and the payment methods we support (Cards, Apple Pay, Google Pay, Balance, Bank Transfer, PISP, UPI, Direct Debit, and more).
What will you be working on?
Rather than owning a single payment method, we build the Payin Session and Payment abstractions that let every product integrate a payment method once and scale to millions of transactions without re-solving the same problems.
This is a high-volume, high-leverage platform role: the systems you build are used by many teams across the company, so correctness, reliability, and thoughtful API design matter enormously.
Qualifications
What do you need?:
- 5+ years of experience in Java, Kotlin, Python or Go
- Strong experience with Spring framework, relational databases, distributed and concurrent systems (Kafka)
- Great cross-team communication
- Can discuss and champion complex, technical topics with a wide and varied audience, from fellow engineers to non-technical stakeholders across lots of teams.
- You enjoy writing testable code and you have experience in testing strategies, such as unit testing, integration testing
- You believe in and follow best coding practices, code reviews and open feedback
- You have great communication skills and the ability to articulate complex, technical concepts to non-technical audience
- You strive to improve our team culture and processes
- A strong product mindset and passion for customer experience, you prioritise work with the customers in mind and make data-driven decisions to fix customer pain-points
- Being able to work independently on customer problems is a key to success
- you take responsibility and end-to-end ownership of your projects: drive and own them to make sure we hit the goals we want to achieve
