Description du poste

Senior Software Engineer - Global KYC and Onboarding

• Full-time
• Compensation: GBP 87,500 - GBP 111,000 - yearly

Wise is a global technology company, building the best way to move and manage the world’s money.
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.

More about our mission and what we offer .

We are currently only considering local candidates as relocation support is not provided for this role. For local candidates we are able to support transfer of visa sponsorship.

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!

You have 4+ years of experience working with any language,asynchronous message queues (e.g., Kafka, RabbitMQ), and have architected and built highly scalable microservices.

A strong product mindset and a deep passion for both customer experience and regulatory compliance.

What does success look like?

You’ll have deeply embedded yourself within our mission, owning and delivering quarterly goals for the team, significantly impacting our ability to scale and improve verification processes.

You’ll own the technical roadmap for your areas, ensuring it supports both immediate delivery needs and long-term strategic objectives, including addressing technical debt and improving system health.

You’ll leverage your expertise to identify the right solutions to solve ambiguous, open-ended problems, driving tough prioritization decisions that deliver clear business and customer value.

You’ll consistently define and implement technical solutions or efficient operational processes that level up your team and contribute beyond it, mentoring other engineers and sharing best practices.

You’ll inspire a high-performing team environment where ideas are shared, technical excellence is pursued, and continuous learning is embraced.

• Unfortunately we cannot offer relocation for this type of role but we can sponsor internal VISAs

For everyone, everywhere. We're people building money without borders — without judgement or prejudice, too. We believe teams are strongest when they are diverse, equitable and inclusive.

Inclusive teams help us live our values and make sure every Wiser feels respected, empowered to contribute towards our mission and able to progress in their careers.
