Fullstack Developer – Client Portal Platform

Mid–Senior Level | Engineering – Integrations & Product

About the Role

Our client portal platform is a cloud-based web application that gives customers of professional services firms a browser-based and mobile experience to view their account information, access documents, and communicate with their service provider. Its built to be scalable, modular, brandable, and easy to integrate into each clients existing infrastructure.

Were looking for a mid-to-senior fullstack developer to help build and evolve this platform end to end — from the Java/Spring backend services to the React-based frontend — while working closely with the teams responsible for third‑party integrations, platform infrastructure, and the wider product.

What Youll Do

• Design, build, and maintain features across the platforms stack, spanning multiple regional environments
• Develop backend services in Java 17 with Maven, and frontend components in React with Yarn
• Work with PostgreSQL and MongoDB (Atlas Database) to model, query, and optimise account and document data
• Integrate with regional identity providers (Keycloak) for authentication, and with internal data and document-archive services for account and document data
• Contribute to the work needed for integration with a third‑party back-office platform, including required user‑management functionality, and support both pull and push data flows
• Write clean, tested, well‑documented code, and take part actively in code reviews
• Collaborate with Product, QA, and DevOps within an agile setup — sprint planning, refinement, and retros
• Help troubleshoot issues across the stack, including occasional 2nd‑line support and root‑cause analysis
• Contribute to CI/CD pipelines and deployments on AWS
• Help keep the portal scalable, modular, and brandable as new clients and integrations come on board

What Were Looking For

• 4–7 years of professional experience as a fullstack developer
• Hands‑on backend experience with Java 17 and Maven
• Hands‑on frontend experience with React and Yarn
• Practical experience with both a relational database (PostgreSQL) and a document database (MongoDB)
• Comfortable working across the stack and owning a feature from API to UI
• Good communication skills and comfort working with distributed, cross‑functional teams
• A pragmatic, quality‑conscious approach to code, testing, and documentation

Nice to Have

• Experience with AWS (ECS, Secrets Manager, VPN/networking basics)
• Familiarity with SSO/OIDC and Keycloak
• Exposure to B2B SaaS platforms, client portals, or back‑office integration domains
