Principal Architect - Node.js, TypeScript, React, experience using AI Agent tools || Remote || W2 & C2C

We are seeking a Principal Architect with strong hands-on experience in Node.js, TypeScript, React, API architecture, and AI Agent technologies to lead architecture initiatives for an API Discovery, Inventory & Rationalization workstream.

The ideal candidate will have deep expertise in modern application architecture, API ecosystems, enterprise integration, and AI-assisted engineering. This role will define architecture patterns and technical strategies for discovering, cataloging, analyzing, rationalizing, and modernizing enterprise APIs using intelligent automation and AI Agent capabilities.

Key Responsibilities

• Define and lead the technical architecture and solution strategy for API Discovery, Inventory, and Rationalization.

• Architect scalable applications and services using Node.js, TypeScript, and React.

• Design and implement frameworks for discovering APIs across enterprise applications, repositories, gateways, documentation, and runtime environments.

• Define API inventory and cataloging strategies, including API ownership, consumers, dependencies, lifecycle, versions, usage, and health.

• Lead API rationalization initiatives to identify duplicate, redundant, obsolete, overlapping, and modernization candidates.

• Leverage AI Agents, Agentic AI, LLMs, and AI-assisted development tools to automate API discovery, classification, documentation, dependency analysis, and rationalization.

• Evaluate and integrate AI Agent tools/frameworks into enterprise engineering workflows.

• Design intelligent workflows that can analyze API specifications, source code, documentation, logs, traffic patterns, and metadata.

• Establish enterprise-level API architecture standards, governance, design patterns, and best practices.

• Design RESTful APIs, event-driven integrations, microservices, and cloud-native architectures.

• Collaborate with engineering, product, security, platform, data, and enterprise architecture teams.

• Provide technical leadership and architectural guidance to senior engineers and development teams.

• Evaluate technology choices, conduct architecture reviews, and drive proof-of-concepts for emerging technologies.

• Ensure solutions meet requirements for scalability, security, reliability, observability, performance, and maintainability.

• Drive API modernization and migration strategies where legacy APIs can be consolidated, replaced, or retired.

• Establish CI/CD and automation patterns supporting API lifecycle management.

• Create architecture documentation, reference architectures, technical standards, and decision records.
