Grey Parrot Systems is hiring an experienced API Solution Architect with deep Node.js expertise and proven LLM-powered agentic engineering experience to design, modernize, and govern enterprise-scale API solutions across cloud-native platforms. About Grey Parrot Systems Grey Parrot Systems is a women-owned, BEP-certified IT services firm headquartered in Naperville, IL. We partner with mid-market enterprises to deliver AI-first, governance-driven digital transformation. Our team of seasoned CIO/CTO practitioners works side-by-side with clients across retail, logistics, manufacturing, and healthcare — and we're growing.
About the Role:
This is a principal-level API architecture role for a Node.js expert who combines deep enterprise API architecture expertise with cutting-edge AI-assisted engineering experience — including designing agentic API migration factories using chained LLM-driven pipelines with human-gated PR reviews. You will lead the architecture of secure, scalable, and high-performing APIs while driving API transformation and integration initiatives across cloud-native platforms. If you have 10+ years of software engineering experience with 5+ years in solution or enterprise architecture — and you are already building with LLMs, GitHub Copilot custom skills, and agentic engineering workflows — this role was built for you.
Must-Have:
- Skills 10+ years of software engineering experience with 5+ years in Solution Architecture, Principal Architecture, or Enterprise Architecture roles
- Strong hands-on expertise in Node.js, JavaScript, TypeScript, Express.js, NestJS, and Fastify
- Proven experience designing and implementing enterprise-scale API platforms and integration architectures
- Experience building agentic API migration factories — chained LLM-driven pipelines with human-gated PR reviews for legacy-to-modern API transformationExperience authoring and governing custom GitHub Copilot Skills and AI-assisted engineering accelerators as reusable delivery artifacts
- Deep expertise in REST, GraphQL, gRPC, WebSockets, and event-driven integration patterns
- Strong API security expertise — OAuth2, JWT, SSO, encryption, rate limiting, and threat mitigation controls
- Experience with API management platforms — Apigee, Kong, AWS API Gateway, MuleSoft, or equivalent
- Hands-on cloud platform experience — AWS, Azure, and/or GCPExperience with Docker, Kubernetes, serverless architectures, and container orchestration
- Strong CI/CD pipeline, DevSecOps, and automated testing framework experience
- Experience with SQL and NoSQL databases — PostgreSQL, MongoDB, DynamoDB, or equivalent
- Strong OAS-first (OpenAPI Specification) development workflow design and governance experience
- Excellent communication, stakeholder management, and technical leadership skills
What You'll Do:
