Responsibilities

• Agentic Workflows: Design and deploy multi-agent workflows within AWS Agent Core, effectively handling state management, memory persistence, and complex tool interactions.
• AI Leadership & Enablement: Help drive internal education and coaching initiatives for tools with as Google Gemini Enterprise; collaborate with external AI partners on new agentic opportunities.

• Strategic Data Orchestration: Make critical trade-off decisions on data orchestration (e.g., MCP/API, Agents/Skills) based on robust data and requirements.

• CI/CD Optimization: Build and optimize CI/CD pipelines, focusing heavily on reducing build times and tightening feedback loops.
• Incident & Operations Leadership: Own Incidents for your services during outages. Create step-by-step triage runbooks and playbooks that empower Tier 1/2 helpdesk teams or junior analysts to resolve common platform errors without escalation.
• Requirement Definition: Partner with Product Managers who define Functional requirements by owning the Non-Functional requirements (Performance, Security, Scalability) needed to meet business KPIs.
• Backlog & Scope Negotiation: Work with PMs to prioritize the backlog, explicitly negotiating the inclusion of tech debt and refactoring.
• Solution-Oriented Mindset: You don't say 'No'; you say 'Not like that.' You offer alternative solutions that respect time and budget constraints.
• Empathic Mentorship & Review: Enforce strict quality standards during code reviews with empathy; mentor SDE 1s and 2s, delegating work to grow them.
• Consensus Building: Facilitate data-driven discussions to resolve engineering disagreements and ensure quiet voices are heard in design meetings.
• Continuous Learning: Rapidly learn and apply new languages or frameworks, lead knowledge-sharing sessions, and adapt across workstreams.
