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 an AI/Backend Engineer to own and evolve our LLM orchestration pipeline. You’ll be the first dedicated engineering hire, working directly with our CTO to transform Sophie from a working prototype into a scalable, enterprise-ready platform.

This is a high-impact, high-autonomy role. You’ll shape technical decisions that define the product for years to come.

What You’ll Do

Own the AI Pipeline

• Design and optimize our multi-agent orchestration system

• Implement parallelization and streaming to dramatically reduce response latency

• Build robust prompt management with versioning and A/B testing capabilities

Build RAG Systems

• Design retrieval-augmented generation for accurate, contextual responses

• Work with vector databases, embeddings, and relevance scoring

• Optimize for both speed and accuracy at scale

Develop Production APIs

• Build developer-friendly APIs connecting our AI capabilities to the frontend

• Design for future integrations with CRMs and advisor tools

• Implement proper authentication, rate limiting, and documentation

Shape the Foundation

• Establish code review practices and testing standards

• Document architecture decisions for future team members

• Contribute to technical patents and IP development

What We’re Looking For

Must Have

• 4+ years production Python experience (async patterns, type hints)

• Hands-on experience with LLM APIs (OpenAI, Anthropic, or similar)

• Strong understanding of prompt engineering and multi-step LLM workflows

• Production API development experience (FastAPI or similar)

• Strong SQL and PostgreSQL skills

Great to Have

• Experience with RAG systems and vector databases (Pinecone, Weaviate, pgvector)

• Streaming/real-time implementation experience (SSE, WebSockets)

• TypeScript/JavaScript familiarity

• FinTech or regulated industry backgroundHow 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

How You Work

• Self-directed and comfortable with ambiguity

• Strong written communication (async-first culture)

• Pragmatic problem-solver who ships iteratively

• Collaborative mindset with ego-free approach to feedback

What This Role Is Not

We want to be upfront about expectations:

• Not a pure ML/research role—you’ll apply LLMs, not train them

• Not a management role—near-term focus is individual contribution

• Not fully autonomous—you’ll collaborate closely with the CTO on architecture

• Not 9-to-5—startup intensity applies, though we respect work-life balance

Compensation & Benefits

• Equity: Meaningful early-stage grant with 4-year vesting

• Equipment: Professional Laptop ready to work with AI provided + stipend for remote work when 6 month mark is met

• 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)
