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.

• Define reusable test-data strategies using Excel, generated datasets, synthetic data, and approved production-like samples.
• Drive automation-first testing while identifying scenarios requiring specialized or exploratory validation.

Healthcare Domain Validation

• Provide Quality Engineering leadership for healthcare enterprise services supporting areas such as:
• Member and eligibility
• Provider
• Claims

Automation Framework Engineering

• Architect and enhance BDD-based API automation frameworks using:
• Cucumber
• TestNG
• REST Assured
• Java
• Gradle
• Define reusable feature files, step definitions, API clients, assertion libraries, data utilities, and comparison utilities.
• Develop configurable validation mechanisms capable of supporting different APIs without extensive custom coding.
• Establish coding standards, framework governance, peer reviews, and reusable engineering patterns.
• Optimize automation suites for parallel execution, maintainability, stability, and faster regression cycles.

CI/CD & DevOps Integration

• Integrate API automation into Jenkins/Udeploy CI/CD pipelines.
• Define automated quality gates for builds and deployments.
• Enable API regression suites to execute across development, QA, integration, staging, and release environments.
• Establish mechanisms for:
