Prospera AI - Fullstack Engineer (Frontend focus)
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. Pure frontend specialization isn’t practical at our stage—we need someone who can move fluidly across the stack.
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 actual 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
We want to be upfront about expectations:
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 & Benefits
Equity: Meaningful early-stage grant with 4-year vesting
Time Off: Flexible PTO with a minimum 15 days encouraged
Learning: $1,000 annual professional development budget
Schedule: Flexible hours with 3-4 hours daily overlap (Americas timezones)
