Howie already runs the calendars of busy founders, executives, and teams, and we’re growing quickly. You’ll be responsible for designing, evaluating, and deploying the AI systems that power Howie’s assistant. From programmatic prompt engineering and semantic retrieval to building eval frameworks and integrating LLM-based features into production.

Experience shipping LLM-powered solutions into production.
Strong engineering background with TypeScript/Node.js and Python.
Familiarity with RAG, semantic retrieval, embeddings, and vector databases.
Experience with evaluation/inference platforms and prompt iteration.
Ability to move quickly and independently in a fast-paced environment.
Strong communication skills and eagerness to collaborate across disciplines.
Based in Seattle, WA or willing to relocate (we’re in Fremont).
