Job summary

Invessio is seeking a QA Engineer who emphasizes deep exploratory testing and business logic validation. This role is primarily manual and functional, embedded in the SDLC, focused on stabilization, release readiness, and aligning system behavior with technical intent and business expectations.

This onsite role in Phoenix involves test planning, execution, defect documentation in Azure DevOps, collaboration with product to sharpen acceptance criteria, and ensuring quality early in development

Qualifications

• 3+ years QA experience in SaaS or web applications
• Strong test case writing skills: structured, clear, executable
• Experience with functional, regression, and integration testing
• Experience working within Azure DevOps (ADO) for test case management, defect tracking, sprint collaboration, and release validation workflows
• Ability to clearly document defects, test execution results, and validation status within ADO
• Solid understanding of SDLC and Agile methodology
• Basic SQL skills to independently validate and investigate data without always needing engineering support

Responsibilities

• Write structured, detailed test cases that a stranger could execute exactly with no ambiguity
• Develop test plans from PRDs, user stories, and acceptance criteria
• Execute functional, regression, integration, and exploratory testing
• Document bugs with clear reproduction steps, environment info, and expected vs. actual behavior
• Re-test fixes and verify no regressions were introduced
• Join sprint planning and design reviews to give testability feedback before dev begins
• Flag requirements that are vague, contradictory, or untestable before anyone builds the wrong thing
• Collaborate with product to sharpen acceptance criteria
• Ensure quality considerations are addressed early, not after development is complete
• Validate feature completeness and stability before go/no-go decisions
• Maintain test results, defect trends, and coverage documentation
• Contribute to release readiness criteria: “done” is defined, not assumed
• Provide input into go/no-go decisions based on risk and system confidence levels
• Work with engineers to understand changes and regression risk
• Partner with product to ensure what’s built matches what was specified
• Communicate blockers clearly and early
• Help create alignment between product intent, engineering, and production behavior
• Participate in ADO-driven sprint workflows for QA visibility and traceability across requirements, defects, and releases
