Cross-Team Technical Alignment:  Defining the technical contracts and integration points between Onboarding and other teams across Wise, such as Marketing, FinCrime, and KYC. End-to-End Journey Ownership:  Building and evolving robust, scalable onboarding flows from account creation through to a customer's first successful transfer. System Health & Performance:  Leading initiatives to improve the maintainability, latency, and cost efficiency of our core onboarding systems.

Qualifications

What do you need? Deep Backend Expertise:  Solid, production-proven experience with Java (or similar OOP languages) and modern (micro)service architectures. Distributed Systems Knowledge:  Strong experience building and scaling distributed, high-throughput systems. Advanced Architecture Skills:  Experience owning and designing fundamental components, shared libraries, or core infrastructure used across multiple teams. Technical Leadership:  The ability to set a clear technical vision for your area of ownership, and to mentor and grow engineers around you. Product & Customer Mindset:  A strong track record of building customer-facing products, with a good sense of how technical decisions affect the end user. Strong Communication:  Excellent collaboration skills, with the ability to explain complex technical concepts clearly to both technical and non-technical audiences, and to align stakeholders across teams. Nice to Have: Experience working closely with Frontend and/or Mobile engineers and design teams. Background in high-growth consumer products or fintech.
