Integrate agents into product workflows - Integrate AI agents into Microsoft 365, Copilot Studio, Power Platform, AWS services, and internal systems. - Define and maintain action interfaces between agents and deterministic systems (APIs, workflows, runbooks). - Ensure reliable orchestration across conversational and workflow layers. Own quality, evaluation, and governance - Define measurable success criteria for agent outputs. - Build lightweight evaluation frameworks and regression testing for prompts and behavior. - Monitor output quality, hallucination risk, cost, and drift over time. - Establish safe usage guidelines and governance boundaries. Operate and improve in production - Monitor agent usage, reliability, and impact. - Optimize performance, token efficiency, and response structure. - Iterate on agent behavior based on real usage patterns and feedback. - Proactively identify new opportunities where AI agents can improve Product workflows. Qualifications Must-have - 6-8+ years of experience building and owning production systems end to end. - Strong system design skills, including event-driven and serverless architectures, with clear trade-off reasoning. - Experience integrating systems through APIs, webhooks, REST, and Graph. - Practical experience designing or integrating AI or LLM-powered workflows in production. - Strong independent ownership and architectural judgment. - Ability to translate ambiguous business needs into structured, scalable AI-enabled solutions. - Excellent collaboration and communication skills. Critical competencies - Prompt and instruction design as structured system artifacts. - Tool and schema design for AI agents. - Evaluation methodology for AI systems (quality metrics, regression testing, failure pattern analysis). - Understanding of LLM failure modes and mitigation strategies. - Experience designing guardrails, structured outputs, and human approval flows. Nice to have - Experience with Microsoft Copilot Studio, Power Platform, or similar low-code orchestration tools. - Experience with AWS services such as Lambda, Step Functions, EventBridge, or Bedrock. - Familiarity with conversational UX design. - Experience embedding AI into internal productivity workflows.
