Senior Product Engineer Partner Experience

Wise Platform helps banks software companies and large enterprises use Wises infrastructure to offer their customers cross-border payment products through our API. Were a cross-functional team across sales implementation product engineering compliance and analytics based in New York London and Singapore.

Were looking for a Senior Backend Engineer to join our Partner Experience team in London.

The Partner Experience team builds and runs the systems that let enterprise partners go live faster and manage their day-to-day operations in one place. 

We own the Partner Portal (used by many big banks to manage transfers report fraud handle compliance requests and manage their teams) and the backend services behind partner onboarding permissions and communication. Most of what we build is new. Theres no existing playbook for enterprise partner tooling at this scale so youll be designing systems from scratch more often than maintaining existing ones.

How we work:

Were a small team that ships frequently and iterates on real partner feedback. Engineers own features from technical discovery and design through to production support. We work closely with our PM and designer to understand partner needs and with adjacent teams (API Experience Account Discovery KYC FinCrime) to pull their capabilities into the portal.

We investigate before we build. That means managing ambiguity understanding the existing systems APIs and dependencies before writing code. We keep process light: quick standups focused 1:1s and quarterly planning.

What will you be working on:

Backend microservices for partner-facing features: fraud reporting case management RFI handling audit logging and transaction visibility.

The permissions and role-based access control system that governs what partners can do in the portal.

SSO (SAML 2.0) integration for enterprise partners including solving identity mapping between partner systems and Wise.

The communication layer services between Wise and partners extending them to handle new case types and workflows.

API design for partner-facing endpoints. We care about consistency documentation and making them usable without hand-holding.

Work with FinCrime Compliance and KYC teams to bring sanctions RFI workflows and fraud reporting into the portal.

Technical discovery: mapping existing systems evaluating dependencies producing design documents that become the teams source of truth.

Production support and debugging when live partner issues come up.

Qualifications :

What do you need:

Experience designing building and deploying backend microservices in Java and Spring Boot.

Familiarity with domain-driven design event-driven architecture and microservices patterns. You think in terms of domain boundaries aggregates and service responsibilities.

Experience designing and maintaining RESTful APIs commercially. Comfort with OpenAPI/Swagger OAuth2 and versioning strategies.

Ability to design and maintain relational databases (MySQL PostgreSQL) including query performance indexing and data modelling.

You enjoy mapping complex technical landscapes: understanding existing systems dependencies and constraints before proposing solutions. You write clear documentation of what you find.

You deliver reliably and manage your own work without needing constant check-ins

You work well with adjacent teams unblock yourself when dependencies come up and build relationships that go beyond PR reviews.

You understand what large enterprise customers need from software: reliability auditability compliance and security as design constraints not bolt-ons.

Nice to have:

Experience building enterprise portals partner platforms or B2B SaaS products.

Understanding of payments systems and the complexities of cross-border money movement.

Experience with identity and access management (SAML SSO SPIFFE OAuth2).

Familiarity with Kafka or other event streaming platforms.

Experience in a platform team serving multiple internal or external consumers.

Ability to explain technical decisions to non-technical people (product managers partners compliance teams).

Interest in international finance foreign exchange or payments infrastructure.
