Are you a fit?
Sounds awesome, right? Now, let's make sure you're a good fit for the role:

Key Responsibilities
- Architect and ship end-to-end agentic and LLM-powered tools for business-facing use cases, deciding when to use a single LLM call, an iterative LLM loop, or a full multi-agent system based on real task complexity.
- Design AI-agnostic, model-flexible services that allow the team to evaluate and swap the best-performing model for each task.
- Build production tools that transform raw content into structured, ready-to-use output — for example,



systems that reformat content to defined templates/guidelines or consolidate multiple sources into a single, fact-accurate output without inventing information.
- Develop and maintain RAG pipelines and vector database integrations to support retrieval-driven features such as content linking and recommendations.
- Establish and scale prompt evaluation, testing, and regression-control frameworks (e.g., via Braintrust, MCP tooling, LangFuse) so quality holds as tools expand across teams and use cases.
- Take AI features from prototype/PoC through to deployed, end-user-facing production tools, working across the full stack (AI core services in Python/TypeScript, front-end integration in React/Vue/Next.js) without relying on handoffs to other teams.
- Partner with stakeholders and engineering leadership to gather feedback, measure impact (e.g., time saved, approval rates), and iterate on tools in production.
- Extend proven architectures to onboard new use cases as configuration rather than one-off reb
