Staff AI Engineer - San Francisco, CA

Company: YC-backed seed-stage startup, operating in the AI wealth management space. They're building a next-gen financial platform aimed at replacing the traditional advisor model - giving everyday accredited investors access to alternative assets through an AI-native, mobile-first experience. Think personalized wealth management meets intelligent automation, built for a generation that doesn't want to walk into a JP Morgan branch. Team of ~10, fast-moving, high-ownership culture.

The Role: As a Staff AI Engineer, you'll be a technical leader and hands-on builder shaping the core intelligence layer of the platform. This isn't a feature team - AI is the product. You'll own agentic systems end-to-end, bring voice modalities to life, and set the engineering bar for a small but growing team.

What You'll Be Doing:

Designing and building multi-agent pipelines for real-time investor research and decision support
Leading AI orchestration using LangChain with a strong focus on latency and real-time performance
Building RAG pipelines over messy, proprietary financial data
Owning observability, evaluation, and reliability across production AI workflows
Mentoring engineers and helping define how AI gets built at the company

What We're Looking For:

6+ years of engineering experience with deep applied AI/ML work
Strong Python and backend fundamentals; hands-on with FastAPI, AWS, DynamoDB
Solid LLM experience - RAG, agents, orchestration, evaluation
Voice AI experience a strong plus (real-time audio, TTS/STS pipelines)
Startup background strongly preferred - this is a scrappy, high-ownership environment
Must be authorized to work in the US without sponsorship

Desired Skills and Experience

*AI Agents + Voice (TTS, STS, etc)-- Orchestration w/ Langchain
*AI tool proficient, latency improvement, real-time voice
*FastAPI, AWS, DynamoDB
