## About the role

Design, build, and deploy production-grade GenAI systems -- including RAG architectures, vector databases, LLM integrations, and tool-call frameworks -- in support of Saga, Rune's AI agentic product layer. Build and maintain evaluation and testing harnesses to validate LLM output quality and catch regressions in production.

## What they're looking for

- 6+ years of experience in software engineering, with a strong backend foundation -- distributed systems, APIs, production-grade software
- Hands-on experience building GenAI systems: vector databases, LLM integration, RAG architectures, and evaluation harnesses for LLM output
- Familiarity with tool routing, tool-call validation, and common LLM failure modes
- Understanding of the science underlying the systems you build -- not just how to wire them together, but why they work and where they break
- Background at an AI-native company, or a clear transition from backend engineering into AI specialization
- Strong sense of ownership and a bias for action
