Mobile Qa Engineer Jobs in Arizona (NOW HIRING)

QA Engineer

Manual & Functional Testing Focused (NOT A REMTOTE POSITION)

About the Role

Invessio is building the infrastructure for modern investment management. Quality here isn't a final gate. It's baked in from day one. We're looking for a QA Engineer who brings systematic, intentional skepticism to every sprint: someone who reads the PRD before dev picks up the ticket and treats vague acceptance criteria as a blocker, not a to-do.

This role is primarily manual and functional, but manual doesn't mean clicking through happy paths. It means deep exploratory testing, business logic validation, and being the person who asks the question no one else thought to ask.

This role is also deeply embedded in the software development lifecycle and plays a critical role in stabilization, release readiness, and ensuring system behavior aligns with both technical intent and business expectations.

What You'll Do

Test Planning & Execution

• 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

Business Logic & Data Validation

• 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

• Identify edge cases that only surface under specific data conditions

Early Lifecycle QA

• 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

Release Readiness

• 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

Stabilization & Risk-Based Testing

• Prioritize testing efforts based on risk, impact, and known system instability areas

• Focus validation on high-risk workflows, calculations, and data dependencies

• Support stabilization efforts by identifying patterns in defects and recurring failure points

• Operate effectively in environments where not everything is fully defined or fully stable

Collaboration

• 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

What We're Looking For

Required

• 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

Preferred

• Experience in fintech, financial platforms, or calculation-heavy systems

• Exposure to API testing (Postman or similar) for backend validation

• Familiarity with exploratory testing techniques and session-based testing

• Experience providing testability feedback on PRDs or specifications

• Experience working in stabilization phases or partially mature product environments

• Exposure to test automation or interest in building automated test coverage over time

Mindset

• Thinks like a user, breaks like an adversary

• Knows the difference between no bugs found and no bugs exist

• Shows up in planning, not just at the end of the pipeline

• Treats reproducibility as everything

• Understands that QA owns the question: does this actually do what we said it would, under real conditions?

• Understands that not all areas carry equal risk and knows how to prioritize testing accordingly

• Comfortable operating in ambiguity and helping create clarity where it doesn't exist

• 100% Employer Paid Medical for Employee AND Whole Family Includes the Mayo Clinic
• 401k/Roth Plan 4% Match with Immediate Vesting
• Dental Insurance
• Vision Insurance
• Company Paid Term Life Insurance
• Company Paid Short-and Long-Term Disability Insurance
• Voluntary Pet Discount Plan
• Fully Subsidized LifeTime Gym Membership*
• Student Loan Repayment
• Tuition Reimbursement
• Catered Friday Lunches
• Stocked Kitchens
• Opportunity to Work at a Fast-Growing Company
• And More!
