Job Description
Wise is looking for a Senior Software Engineer I - KYC & Onboarding to join its Servicing department in London on a full-time, on-site basis.

This position suits an experienced developer who wants to build configuration-driven financial crime and KYC products, scale microservices, and incorporate machine learning and AI into decision-making and operational workflows. As a senior team member, you will own large-scale projects, drive technical roadmaps, design backend systems with clean APIs, and integrate risk mitigation systems to maintain compliance.
Wise maintains a bottom-up, transparent culture that values high ownership, data-driven decision-making, and collaboration among backend and frontend engineers, mobile developers, designers, data analysts, and product managers. You will lead technical delivery, address technical debt, mentor other engineers, and solve complex, ambiguous problems that remove barriers to financial freedom for individuals and small businesses.

- Define and implement technical solutions or operational processes that level up the team and mentor other engineers
- Lead the technical delivery of large-scale, organizationally complex projects while anticipating and escalating blockers
Requirements
- Minimum of 4 years of software engineering experience working with any programming language

- Proven background in architecting and building highly scalable microservices
- Experience working with relational and non-relational databases, including schema design, query optimization, and data lifecycle management for sensitive data
