Job Description:

Flanks is shaking up the wealth management industry by making it simpler and way more efficient for financial institutions. Our SaaS platform is designed to help banks, family offices, and wealth managers get a full picture of their clients' financial assets—all in one place. We’re building the next generation of financial automation at Flanks: a multi-agent AI platform that reasons, fetches data, validates information, and works alongside humans in real time. As we scale this new system, we’re facing fresh technical challenges — and that’s where you come in.

Job Responsibility:

Own the architecture of the AI/multi-agent frontend (Vue + Nuxt), from early design to production readiness
Maintain and evolve tooling, CI/CD, testing strategy, and internal component libraries relevant to the AI product area
Build event-driven UIs using WebSockets/SSE to show streaming agent responses, live logs, system state transitions, execution traces
Ensure all real-time views are smooth, performant, and reliable
Build rich, interactive components for conversation UIs, agent graphs/flows, timelines, status panels, and debugging views
Craft dense financial data dashboards that support auditing, validation, and decision-making
Work closely with backend, ML, and infra teams to define events, APIs, and schemas
Ensure the frontend reflects the underlying multi-agent system with accuracy and clarity
Partner with Product and Design to create UX patterns for AI interactions
Mentor engineers on frontend best practices, especially around real-time apps and visualization
Contribute to architectural discussions, standards, and documentation

Requirements:

Expert-level frontend skills with Vue + Nuxt, including scalable component architecture, state management, routing, and performance tuning
Real-time UI experience using WebSockets/SSE or other event-driven streaming patterns
Strong experience building complex dashboards and data visualizations (D3.js, Cytoscape, Vue Flow, or similar)
Comfortable using Docker / Docker Compose for local multi-service development
Familiarity with backend concepts, API design, and event schemas
7+ years in software engineering (senior-level)
Fluent in Spanish and English

Nice to have:

Experience with real-time apps, data-heavy UIs, or AI-driven products is a strong plus
Wealth/financial knowledge is a bonus
