Resumo da vaga

Conteúdo da vaga extraído em seções para revisão mais rápida.

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 the implementation of our evolving design system, translating UX designs into reusable, accessible components using SAP UI5 Web Components and TypeScript. Establish patterns for dashboards, data tables, search interfaces, and detail views.
BFF Collaboration: Work closely with the BFF layer (Spring Boot) to shape API contracts, optimize data-fetching patterns, and ensure the portal proxy controllers deliver exactly what the frontend needs. Influence the design of search proxy endpoints and OpenAPI specifications.
Performance & Accessibility: Champion frontend performance optimization (lazy loading, caching strategies, efficient re-renders) and WCAG accessibility standards across all portal views.

Search & Data Views: Architect the frontend implementation of our new standardized search framework, integrating table-based server-side pagination, sorting, and filtering via our REST filter contracts. Implement column configuration, saved searches, and spreadsheet exports.
Dashboard & Analytics UX: Build rich, interactive dashboard experiences including payment summaries, held-payment alerts, trend charts, and failure-analysis views.
Implement data visualizations that surface actionable insights for enterprise payment operations.
Cross-Functional Leadership: Partner with Product, Design, and Platform teams to translate business requirements into UX solutions. Drive UX technical decisions and advocate for user experience quality in architectural discussions.
Mentorship: Mentor mid-level and junior engineers on frontend best practices, code quality, component design, and UX engineering principles. Lead code reviews, establish coding standards, and help shape the engineering culture as the team grows.

7+ years of software engineering experience with a strong focus on frontend development and UX engineering
Expert proficiency in TypeScript and modern JavaScript.
Expert-level React experience, including deep knowledge of hooks, state management patterns, and component architecture, with a track record of building complex, data-rich web applications
Hands-on experience with headless table libraries (TanStack Table preferred) including server-side pagination, sorting, and filtering
Proven ability to build responsive, accessible (WCAG 2.1 AA) interfaces for enterprise applications
Experience with BFF (Backend for Frontend) patterns and REST API integration, including OpenAPI-generated clients
Solid understanding of authentication flows (OAuth2/OIDC, session-based auth) and security best practices (CSRF, CSP)
Experience with AI agent frontends — streaming UI, conversation management, and integration with Spring AI, LangChain, or MCP backends
Experience with data visualization libraries and building dashboard interfaces with charts and analytics components
Strong system design skills with the ability to influence architecture decisions across frontend and API layers
Excellent communication skills and experience collaborating in cross-functional agile teams
Professional fluency in English (written and verbal) is required; all engineering collaboration, documentation, code reviews, and stakeholder communication are conducted in English

Experience with SAP UI5, SAP UI5 Web Components, or enterprise UI frameworks in regulated industries
Familiarity with Spring Boot BFF architectures and Java/Kotlin backend services
Background in fintech, payment processing, or B2B financial platforms
Experience with SheetJS or similar client-side data export libraries
Knowledge of JPA Specifications or similar backend query patterns and how they map to frontend filter UIs
Experience building multi-tenant SaaS applications with organization-scoped data access
Track record of leading frontend architecture decisions and establishing engineering standards

Shape the Product: Own the UX of a platform that processes millions in B2B payments.
Your work directly impacts how enterprise customers manage counterparties, execute payments, and maintain compliance.
Technical Voice: Your opinions on API design, BFF contracts, and component architecture will directly influence how our stack is built. You won't just consume APIs – you'll help shape them.
Modern Stack: Work with a thoughtfully chosen technology stack that values simplicity and pragmatism over hype. We adopt new tools where they add real value.
Early-Stage Impact: Join a well-funded startup where your contributions shape both the product and the engineering culture from the ground up.
Full-Stack Exposure: Collaborate across the entire stack, from frontend components to BFF orchestration to backend service APIs.
AI-Forward Culture: We embrace AI as a tool for innovation and efficiency. We are looking for team members who are curious, adaptable, and excited to leverage AI in their work.
Team & Growth: Work with a collaborative, diverse team that values technical excellence, continuous learning, and work-life balance.
