Job summary

Invessio is seeking a QA Engineer focused on manual and functional testing, with an emphasis on deep exploratory testing, data validation, and collaboration across the SDLC. The role involves stabilizing releases and ensuring system behavior aligns with business goals.

Candidates should bring strong test-case writing, SDLC knowledge, and basic SQL skills. This onsite position emphasizes collaboration during sprints and early testability feedback.

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
• Validate calculations, servicing logic, and workflow outputs against expected behavior
• Cross-check data against source of truth datasets to catch inconsistencies and drift
• Validate system outputs against defined calculation models and expected business logic
• 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 clear input into go/no-go decisions based on risk, known issues, and system confidence levels
• Work with engineers to understand what changed and where regression risk is highest
• Partner with product to ensure what’s built matches what was specified
• Communicate blockers clearly and early, no surprises at the end of a sprint
• Help create alignment between product intent, engineering implementation, and production behavior
• Participate actively in ADO-driven sprint workflows, ensuring QA visibility and traceability across requirements, defects, and releases
