Senior II/Lead Software Engineer - Global KYC and Onboarding

Description

You would join the Global KYC and Onboarding squad in the Servicing department. The squad helps teams across the globe expand and adjust the business through configuration changes, while keeping customers safe and the company compliant.

The squad has three teams: Business Onboarding Verification, Personal Onboarding Verification, and a B2B platform verification team.

In FY2025, 15.6 million people and businesses used the company. It onboarded 5.9 million new customers (about 500k a month) and moved £145.2bn across borders (about £400m a day) across 160+ countries and 40+ currencies.

The verification systems are core production infrastructure. They must stay reliable as regulations, policies and fraud patterns change.

Current priorities are a configuration-driven KYC and FinCrime product, rebuilding systems as scalable microservices, and using ML and AI to improve decisions, review quality and efficiency, with safe fallbacks and clear observability.

Teams are cross-functional and include backend and frontend engineers, mobile developers, designers, data analysts and product managers. The squad owns the full verification lifecycle, from document collection to agent tooling and compliance monitoring.

In this IC4 role you would shape architecture across the squad's services, lead technical direction on initiatives such as the configuration-driven KYC platform, and raise the engineering bar through mentoring and influence across teams.

The interview process helps match you to the team that fits your skills best.
