Role Overview We are seeking a Senior QA Analyst who excels at navigating complex enterprise ecosystems. This role is critical for our migration journey, requiring someone who can rigorously test legacy .NET Framework applications while validating new features in a modern React/.NET 6 environment.

The ideal candidate brings a strong background in Salesforce testing and SQL, ensuring that data flows seamlessly between our custom applications and our CRM. While we are moving toward automation with Playwright, this role is primarily focused on expert manual testing, data integrity, and cross-system validation.##

Key Responsibilities
* Migration Testing:
Validate that business logic remains consistent as we migrate from legacy .NET 4.8 monoliths to modern .NET 6 microservices.
* Salesforce Validation:
Test integrations between our internal applications and Salesforce, ensuring lead data, customer records, and workflows sync correctly.
* Advanced Data Testing:
Use SQL to perform "under-the-hood" verification, ensuring that the database reflects the UI actions and that no data is lost during migration.
* End-to-End Functional Testing:
Perform deep-dive manual testing on React-based frontends, focusing on user experience, browser compatibility, and edge-case scenarios.
* Regression Management:
Maintain a high-quality bar for legacy systems while simultaneously testing new cloud-native (AWS) features.

* Collaboration:

Work closely with developers to translate complex business requirements into executable test plans.## Technical Requirements Core QA Competencies
* Manual Testing Excellence: 6+ years of experience in manual QA, specifically with complex enterprise-level web applications.
* Legacy vs. Modern:
Proven experience testing both legacy .NET environments and modern SPAs (React/Type Script).
* SQL Mastery:
Ability to write complex queries (Joins, Unions, Aggregate functions) to validate backend data without relying on the UI.Platform & Tools
* Salesforce:
Experience testing Salesforce modules (Sales/Service Cloud) and verifying third-party integrations.
* API Testing:
Proficient with Postman or similar tools to test REST APIs.
* AWS Environment:
Familiarity with testing in cloud environments and using tools like Cloud Watch to check application logs.

Preferred "Add-on" Skills
* Automation Curiosity:
While this is a manual-heavy role, any familiarity with Playwright (or a desire to learn it) is a significant plus as we build out our automation suite.
* Testing Tools:

Experience with Jira, Azure Dev Ops, or Test Rail for defect tracking and test case management.##
