Principal Engineer, Technical Content Experience Team (TCX)

Amazon • Arlington, VA

4d • Onsite

About The Position

Define the technical direction for a 60-person engineering organization building the AI-first content platform for AWS documentation — one of the most visited technical documentation sites in the world. You'll work across six engineering teams spanning content management, publishing infrastructure, content automation, AI/ML, knowledge graphs, and content delivery to drive architectural coherence and make the hard technical bets that determine whether this platform succeeds.

The fundamental question you'll help answer: in an era where developers increasingly interact with AI agents instead of reading documentation, what should a content platform actually be? The answer isn't obvious, and it's changing fast. You'll operate in a space where the right architecture depends on assumptions about AI capabilities 2–3 years out, where you're balancing a live production system serving millions of users against a platform transformation, and where the technical decisions have direct product implications.

This is a role for an engineer who wants to shape how a large organization navigates a genuine technology inflection point — not incrementally improving an existing system, but figuring out what the system should become.

Requirements

• 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

Nice To Haves

• 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

Responsibilities

• 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 — data flow architecture, API contracts, platform boundaries, migration strategy
• 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

Benefits

• health insurance (medical, dental, vision, prescription, Basic Life & AD&D insurance and option for Supplemental life plans, EAP, Mental Health Support, Medical Advice Line, Flexible Spending Accounts, Adoption and Surrogacy Reimbursement coverage)
• 401(k) matching
• paid time off
• parental leave
• sign-on payments
• restricted stock units (RSUs)
