Job Description

About You

You are an experienced Senior Functional QA Engineer who enjoys understanding complex business workflows and uncovering risks beyond standard happy-path scenarios. You bring a strong quality mindset to SaaS and enterprise environments, with the ability to understand how configurations, transactional processes, integrations, and downstream data flows interact across a broader ecosystem.

You are comfortable independently turning complex requirements into structured test strategies, executing detailed functional testing through web-based interfaces, and validating integration points and existing data-parity results. You bring strong analytical judgment, attention to detail, and disciplined documentation practices, while collaborating effectively with platform administrators, business stakeholders, and technical teams.

Note: This is a temporary 6-month opportunity requiring consistent overlap with Pacific Time business hours.

You Bring to Applaudo the Following Competencies:

• Bachelor’s Degree in Computer Science, Software Engineering, Information Systems, or a related field is desired, or equivalent professional experience.
• 5+ years of professional experience in Functional Quality Assurance, including hands‑on testing of complex SaaS or enterprise applications.
• Strong experience performing functional testing directly through web-based graphical interfaces.
• Proven ability to independently create structured and comprehensive test plans covering business workflows, integrations, negative scenarios, boundary conditions, and edge cases.
• Hands‑on experience testing billing or subscription workflows, including subscription changes, mid‑cycle modifications, invoice generation, and payment events.
• Strong experience with functional, integration, regression, and end‑to‑end testing.
• Hands‑on REST API testing experience using Postman, Newman, or equivalent tools.
• Read‑level SQL knowledge, with the ability to interpret query results and data‑parity reports to identify anomalies and discrepancies.
• Ability to facilitate collaborative testing exercises with platform administrators and technical stakeholders.
• Strong analytical thinking and the ability to identify non‑obvious failure scenarios.
• Detail‑oriented documentation skills, including maintaining test cases, execution evidence, results, and defect logs.
• Professional working proficiency in English.
• Availability to collaborate during Pacific Time business hours.

Nice to Have:

• Hands‑on experience with Zuora Billing, Revenue, or Subscription Management interfaces.
• Experience participating in billing‑platform migrations, ERP transitions, or comparable system‑integration initiatives.
• Familiarity with cloud data platforms or data warehouses, particularly GCP or BigQuery.
• Experience using automated regression‑testing frameworks such as Cypress or pytest.
• ISTQB Foundation certification or an equivalent testing credential.

You Will Be Accountable for the Following Responsibilities:

• Create and maintain a comprehensive functional testing plan for SaaS billing and cloud‑data integrations.
• Design test scenarios covering billing configurations, subscription lifecycle workflows, invoice generation, payment processing, and revenue‑related data flows.
• Execute functional tests primarily through the platform’s graphical interfaces.
• Validate configurations, business workflows, and integration touchpoints across standard, negative, boundary, and edge‑case scenarios.
• Coordinate testing exercises with platform administrators and technical stakeholders, ensuring clear responsibilities, coverage, and expected outcomes.
• Validate REST API integration touchpoints using Postman, Newman, or equivalent tools.
• Review existing data‑parity reports and query results to identify anomalies and flag discrepancies for further investigation.
• Document test cases, execution evidence, results, defects, and retesting outcomes to maintain a complete audit trail.
• Collaborate with business and engineering stakeholders to align functional test coverage with business rules and integration behavior.
• Communicate testing progress, risks, blockers, defects, and quality concerns clearly and proactively.
• Perform regression testing and confirm that resolved defects do not negatively affect related billing or subscription workflows.
