Role Overview
We are seeking an experienced API Test Architect & Solution Lead to lead the quality engineering strategy, architecture, and implementation for large-scale API modernization and microservices transformation programs within the healthcare domain.
The role will be responsible for defining the end-to-end API testing architecture and modernization validation strategy for enterprise services being transformed from legacy/monolithic platforms into modern RESTful APIs and microservices.
This is a customer-facing technical leadership role requiring strong expertise in API testing, test automation architecture, microservices, legacy-to-modern API parity validation, CI/CD integration, healthcare data validation, and AI-assisted Quality Engineering.
The Solution Lead will work closely with enterprise architects, API developers, product owners, business teams, DevOps teams, and QA engineering teams to ensure modernized services meet functional, integration, data integrity, performance, security, and release-readiness requirements.
Key Responsibilities
API Test Architecture & Solutioning
Define the enterprise API Quality Engineering architecture, strategy, standards, and implementation roadmap for API modernization programs.
Design scalable and reusable API automation frameworks supporting hundreds of APIs and thousands of test scenarios.
