## About the role

Savvy is hiring our first dedicated agentic harness engineer. Coding agents are already part of how our engineers work, but adoption has moved faster than our ability to make their output consistently good. Wrong code and weak architectural decisions still create review burden. We are hiring someone to treat that as an engineering problem, not solve it with a longer prompt.

## What they're looking for

- Internal tools with real users: You have built developer tooling or a platform that engineers beyond your immediate team relied on. You learned from their behavior and support burden, not only from what they said they wanted
- CI or large-codebase experience: You have made a meaningful improvement to CI, testing, repository workflows, or developer productivity in a substantial, long-lived codebase
- Product judgment for internal systems: You can interview developers, separate symptoms from root causes, turn evidence into a roadmap, and say no to attractive work that will not improve the system
- Strong software engineering: You have built and operated substantial production software. We are open on language and framework, but you must be able to move from diagnosis to a durable implementation yourself
- Evaluation over intuition: You know that agent behavior is nondeterministic and changing quickly. You compare prompts, context, tools, models, and workflows against representative tasks rather than declaring success from a demo
- Cross-team influence: You can set standards and change defaults across teams without becoming a gatekeeper. You explain the evidence, earn trust, and remain accountable for the experience you create
