AI Engineer
Pathwork, San Francisco - Presidio
The role
We’re hiring an AI engineer, a full-stack, strategic builder who can take a large project from a working prototype to an industry-defining product. You’ll lead development of our agentic AI systems, owning model orchestration, retrieval, real-time inference, evaluation, and production infrastructure, and collaborating closely with the founding team on product and technical strategy.
What you will do
- Build the engine: Design and own end-to-end agentic systems—retrieval, orchestration, inference, eval, and feedback loops
- Scale the stack: Shape our architecture across model interfaces, data pipelines, vector DBs, and streaming infrastructure
- Ship fast: Partner with product and design to prototype, test, and launch AI-driven features that deliver real value
- Improve performance: Continuously optimize accuracy, latency, and robustness through fine-tuning, eval frameworks, and data iteration
- Learn from the field:
