## About the role

Nearly every company in the world runs on custom software for critical operations like tracking performance metrics, handling support workflows, building admin dashboards, and countless processes you might never have thought of. But most companies don't have the resources to properly invest in these tools, leading to a lot of old, clunky internal software, or worse, teams still stuck in manual and spreadsheet workflows.

## What they're looking for

- Work across the product and infrastructure boundary, shaping agent behavior while understanding what it costs at runtime, and serve as the infrastructure team's technical counterpart on agent workloads
- Detect, diagnose, and resolve non-deterministic failures such as hallucinations, partial correctness, instruction drift, or context sensitivity, working from transcripts and traces rather than logs alone
- Partner closely with product and infrastructure teams on how agent workloads are provisioned, isolated, and rolled out, including for self-hosted customers, and set the pattern for how we ship agentic products safely
- Accountable for agent behavior, not just system correctness
- Designing, Building, and Deploying agentic products in both cloud and self-hosted environments
- Grounded in evaluation, iteration, and regression prevention under non-determinism
