Senior Software Developer for WP

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., * 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.

• 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.
