This role involves defining the technical direction for a 60-person engineering organization focused on building an AI-first content platform for AWS documentation. The team operates across six engineering teams, addressing challenges in content management, publishing infrastructure, and AI/ML. The principal engineer will shape the architecture to ensure coherence and address cross-cutting technical problems. This position is critical in navigating a technology inflection point where AI capabilities are rapidly evolving.

• Experience as a principal-level engineer or equivalent technical leader in a large-scale software engineering organization.
• Demonstrated ability to set technical direction across multiple teams or systems.
• Experience designing and evolving distributed systems or platform architecture at scale.
• Experience with AI/ML systems, agentic workflows, or applied AI in production environments.
• Strong written and verbal communication skills, with the ability to clearly articulate technical rationale to both engineering and leadership audiences.
• Experience with knowledge graph architecture, semantic data modeling, or graph-based systems.
• Experience with content management, publishing infrastructure, or developer documentation platforms.
• Familiarity with MCP (Model Context Protocol) server design or agent-accessible API architecture.
• Experience leading platform migrations on live production systems.
• Track record of mentoring senior engineers toward principal-level scope.

• Set technical direction across six engineering teams, ensuring architectural decisions compound rather than conflict.
• Make high-judgment calls on build-vs-integrate-vs-deprecate for systems spanning content management, publishing, AI agents, knowledge graphs, and automation.
• Drive resolution of cross-cutting technical problems that no single team owns, including data flow architecture and API contracts.
• Evaluate and de-risk the organization's technical bets on AI, particularly around agentic content operations and autonomous workflows.
• Raise the engineering bar across the organization through design reviews, mentorship, and establishing technical standards.
• Represent TCX Engineering's technical perspective to senior leadership and partner organizations.

• Employees at Amazon are often offered comprehensive health benefits—including multiple medical plan options (no pre-existing condition exclusions, 100% covered in-network preventive care), dental and vision plans, a 24/7 medical advice line from day one, expert second-opinion services, and broad mental-health support with several free counseling sessions (including pediatric). Financial wellness typically includes a 401(k) with company match (up to 2%), Restricted Stock Units (equity), FSAs, an emergency savings program, product and partner discounts, and even college-savings and home-purchase programs. Overall, the package is designed to support employees and their families’ health, finances, and day-to-day life.
