Job Description
Wise Platform helps banks, software companies, and large enterprises use Wise's infrastructure to offer their customers cross-border payment products through our API. We're a cross-functional team across sales, implementation, product, engineering, compliance, and analytics, based in New York, London, and Singapore.
We're 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. There's no existing playbook for enterprise partner tooling at this scale, so you'll be designing systems from scratch more often than maintaining existing ones.
How we work:
- We're 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 team's source of truth.
- Production support and debugging when live partner issues come up.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
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 modeling.
- 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.
