• Create shared stateful agent experiences across voice, SMS, web chat, and email.
• Build compliant outbound workflows for collections, abandoned-cart follow-up, lead follow-up, and renewals.
• Implement guardrails for payments and tenant records, including confirmation, idempotency, scope limits, and human escalation.
• Integrate agents with legacy APIs using authentication, retries, timeouts, validation, and durable writes.
• Own agents from pilot through production using evaluation sets, regression runs, tracing, and operational metrics.
• Analyze traces, transcripts, failures, and user outcomes to improve completion, reliability, latency, and cost.
• Use AI-assisted development and testing tools and collaborate with product, design, operations, and engineering teams.

• Practical experience with tool or function calling, retrieval-augmented generation, structured model outputs, context management, prompt or context design, or agent-workflow orchestration.
• Experience evaluating and observing nondeterministic systems through task-success measurement, tool-call tracing, cost and latency control, and safe human escalation.
• Experience testing nondeterministic systems and measuring task success, containment, escalation, latency, and inference cost.
• Ability to work onsite in the Seattle, Washington area 2–3 days per week.
• Bonus experience with tenant-specific configuration, sensitive data, permissions, auditability, or security-sensitive workflows.
