Min fees. Max ease. Full speed. Whether people and businesses are sending money to another country, spending abroad, or making and receiving international payments, Wise is on a mission to make their lives easier and save them money. As part of our team, you will be helping us create an entirely new network for the world's money. For everyone, everywhere.We are the Global KYC and Onboarding squad in the Servicing department and we have a mission: to enable teams at Wise to expand and fine-tune the business in a "config change" manner all across the globe, while remaining compliant and safe for the customers. There are three teams in the squad: Business Onboarding Verification, Personal Onboarding Verification and Wise Platform Verification (our B2B platform).The scale we operate at: In FY2025, 15.6 million people and businesses used Wise, we onboarded over 5.9 million new customers (~500k/month), and moved £145.2bn across borders (~£400m/day) across 160+ countries and 40+ currencies. Our verification systems aren't supporting tools — they're core production infrastructure that protects customers, enables growth, and must stay reliable under constant change in regulations, policies, and evolving threat patterns.All of the teams are diverse, cross-functional groups passionate about solving complex problems with elegant solutions. We bring together backend and frontend engineers, mobile developers, designers, data analysts, and product managers who collaborate closely to deliver exceptional customer experiences. Our teams are responsible for the critical verification journeys that business and personal customers complete before using Wise's products. We own the entire verification lifecycle – from document collection flows and automated review systems to agent tooling and compliance monitoring. We operate with high ownership in a bottom-up, transparent culture, make data-driven decisions, and celebrate both technical excellence and customer impact. Right now we're focused on building KYC/FinCrime as a configuration-driven product, refactoring and building new scalable microservice systems, and increasing automation using ML/AI where it genuinely improves decisioning, review quality, and operational efficiency — with safe fallbacks and clear observability. As a team that touches both regulatory requirements and customer experience, we have unique opportunities to innovate in a space traditionally resistant to change.By joining one of our teams, you'll directly impact these customers by transforming a traditionally frustrating experience into one that's fast, intuitive, and fair. Your code will help individuals and small businesses access global banking faster, enable entrepreneurs to pay international employees on time, and allow people like you and your teammates support their families across borders without friction. We're not just building verification systems – we're removing barriers that stand between our customers and their financial freedom.We need like-minded engineers in all the teams in the squad, so we'll use the interview process to discover where your unique skills shine brightest. Ultimately, we want to match you with the team that perfectly aligns with your experience and sets you up for success!As a Senior Software Engineer, you will own large-sized, impactful projects within the domain. Your responsibilities span end-to-end: You will own the technical roadmap for your areas of ownership, ensuring they address important technical debt, reliability, scalability, and security concerns. You will be instrumental in designing and implementing robust backend systems that provide clean APIs and interfaces to hide the internal complexity. You will drive the integration with various risk and mitigation systems to ensure that Wise is compliant. You will take initiative to identify and solve impactful problems both within your team and beyond, contributing to high-impact cross-team initiatives.### Skills Required* Java 8+* Spring framework* Asynchronous message queues (Kafka, RabbitMQ)* Architecting and building highly scalable microservices* Product mindset* Customer experience* Regulatory compliance* Data-driven decisions* Exceptional communication skills* Clean, testable, maintainable, and highly performant code* Best coding practices* Rigorous code reviews* Technical delivery of large-scale, organisationally-complex projects* Relational databases* Non-relational databases* Advanced query optimization* Schema design* Data lifecycle management for sensitive information
