About Prospera AI We're building Sophie, a multi-agent AI orchestrator that helps wealth management advisors deliver more personalized, effective service to their clients. Our platform analyzes behavioral patterns, communication preferences, and emotional states to transform how advisors understand and serve their clients. We're a small, well-funded team at an exciting inflection point — our technology works, customers love the product, and now we're building the engineering team to scale.

The Role

We're looking for a Full-Stack Engineer with a strong frontend focus to transform Sophie's user experience. You'll own how wealth management advisors interact with our AI — making complex, powerful capabilities feel simple and intuitive. This role is ~70% frontend, ~30% backend/integration. You'll primarily build UI/UX, but you'll also connect APIs, occasionally modify backend logic, and contribute to product decisions.

What You'll Do Own the Advisor Experience Build and refine the dashboard where advisors interact with Sophie

Design conversation views, client insights panels, and recommendation displays

Make complex AI outputs feel simple and actionable Build Streaming UI Implement real-time streaming response displays

Create thoughtful loading states and progressive disclosure

Help users understand what the AI is doing — not just wait for results Establish Design Systems Create consistent, reusable component patterns

Document and maintain a component library that accelerates development

Ensure new features feel cohesive with existing product Optimize Performance Ensure fast load times and smooth interactions

Handle edge cases gracefully — advisors use Sophie during client calls

Focus on perceived performance as much as vigente metrics What We're Looking For Must Have 4+ years production React experience with deep understanding of hooks, context,



and rendering optimization

Solid Next.js experience (App Router, server components, API routes)

Strong TypeScript skills — non-negotiable

Proficiency with Tailwind CSS and modern styling approaches

Ability to implement complex, responsive layouts without designer hand-holding Great to Have Experience building streaming/real-time UI (chat apps, live dashboards, collaborative tools)

Component library or design system experience

B2B SaaS background, especially professional services or financial contexts

Comfort with Framer Motion or CSS animations

Basic backend knowledge (Python/Node.js, reading API code) How You Work Strong UX intuition — you notice when flows have one too many clicks

Pragmatic perfectionism — you know when to polish and when to ship

Clear communicator who can explain technical constraints in business terms

Collaborative mindset — frontend doesn't exist in isolation What This Role Is Not Not a pure designer role — you'll implement designs, not create them from scratch

Not a backend role — despite being full-stack, emphasis is heavily frontend

Not a DevOps role — you deploy and debug, but don't manage infrastructure

Not a pixel-pusher role — we value engineers who think about UX, not just execute mockups Compensation &
