Senior Software Developer - Wise Platform

Description

The company Platform lets banks, software companies and large enterprises offer cross-border payment products to their own customers, using the company's infrastructure through an API. The team spans sales, implementation, product, engineering, compliance and analytics, with offices in New York, London and Singapore.

This is a senior backend role on the Partner Experience team in London.

The team builds and runs the systems that help enterprise partners launch faster and handle daily operations from one place.

The team owns the Partner Portal, which large banks use to move money, report fraud, process compliance requests and manage their staff. It also owns the backend services for partner onboarding, permissions and communication. Most of the work is greenfield, with no established playbook for enterprise partner tooling at this scale, so you will often design systems from zero rather than maintain existing ones.

Responsibilities

• Build backend services for partner-facing features such as fraud reporting, case management, RFI handling, audit logging and transaction visibility.
• Develop the role-based permissions system that controls what partners can do in the portal.
• Add SAML 2.0 SSO for enterprise partners, including mapping identities between partner systems and the company.
• Extend the communication services between the company and partners to support new case types and workflows.
• Design partner-facing APIs that are consistent, well documented and easy to use without help.
• Work with the FinCrime, Compliance and KYC teams to bring sanctions RFI workflows and fraud reporting into the portal.
• Carry out technical discovery by mapping existing systems and dependencies, and write design documents that serve as the team's reference.
• Support production systems and debug live partner issues.

Requirements

• Experience designing, building and deploying backend microservices in Java and Spring Boot.
• Working knowledge of domain-driven design, event-driven architecture and microservice patterns, including how to split domains, aggregates and service responsibilities.
• Commercial experience designing and maintaining REST APIs, with familiarity in OpenAPI/Swagger, OAuth2 and versioning approaches.
• Experience designing and maintaining relational databases such as MySQL or PostgreSQL, covering query performance, indexing and data modelling.
• Skill at mapping complicated technical landscapes, including systems, dependencies and constraints, before proposing a solution, and at writing clear notes on what you find.
• You deliver reliably and manage your own work without needing constant check-ins.
• You work well with neighbouring teams, resolve blockers yourself and build working relationships beyond code reviews.
• You understand what large enterprise customers expect: reliability, auditability, compliance and security designed in from the start.
• Experience building enterprise portals, partner platforms or B2B SaaS products.
• Understanding of payments systems and the difficulties of moving money across borders.
• Experience with identity and access management, including SAML, SSO, SPIFFE and OAuth2.
• Familiarity with Kafka or other event streaming platforms.
• Experience working on a platform team that serves several internal or external consumers.
• Ability to explain technical decisions to non-technical audiences such as product managers, partners and compliance teams.
• Interest in international finance, foreign exchange or payments infrastructure.

Conditions

The team is small, ships often and iterates based on real feedback from partners. Engineers own features from discovery and design through to production support. You will work closely with the PM and designer on partner needs, and with API Experience, Account Discovery, KYC and FinCrime to bring their capabilities into the portal.

The team researches before building, so you will handle ambiguity and understand existing systems, APIs and dependencies before writing code. Process is kept light, with quick standups, focused 1:1s and quarterly planning.

Starting salary is £87,500 to £111,000, plus RSUs.

The company is an equal opportunity employer and welcomes people from all backgrounds.
