About Tereina

Tereina is on a mission to revolutionize B2B payments. We are a well-funded, early-stage startup building cutting-edge solutions that transform how businesses move money. Our platform handles cross-border payment processing, counterparty management, bank account administration, and compliance workflows for enterprise customers worldwide.

We are building a modern portal application using a service-oriented architecture with SpringBoot microservices, a Spring Boot BFF (Backend for Frontend), and a custom frontend built with SAP UI5 Web Components, React and TypeScript. We are currently evolving our UX with a clean, data-rich design language focused on advanced search, tabular data views, and dashboard analytics.

About the Role

As a Senior Fullstack Engineer, you will be a key technical leader responsible for shaping the user experience of the Tereina Portal. You will own the frontend architecture, drive the implementation of our new design system, and work across the full stack to ensure our UX vision is realized with production-quality code.



You will partner closely with product, design, and backend engineers to deliver enterprise-grade interfaces for payment operations, counterparty management, and compliance with workflows.

This role demands deep expertise in modern frontend technologies, a strong eye for design quality, and the ability to influence architecture decisions across the portal and its supporting BFF layer. You will mentor other engineers on UX best practices and help define our standards for accessibility, performance, and component reusability.

Key Responsibilities

These are the responsibilities focused on building the underlying systems, architecture, and shared infrastructure:
- Frontend Architecture: Own and evolve the frontend architecture of the Tereina Portal, including the component library, state management patterns, and data-fetching layer built on our existing frontend infrastructure.
- Design System Implementation: Lead
