QA Engineer

Description

We are looking for a QA Engineer who is deeply technical, passionate, and meticulous to help drive a quality-centric approach to application development. This key role is responsible for creating and executing automated tests to ensure product quality for our payment capture systems, tokenization engines, front-end UI, and payment modals.

The ideal candidate will thrive in a large, complex architecture, managing the quality of our microservices/APIs and integrations with other Stax products. You will enhance our team’s ability to implement proper QA tooling and automation while serving as a bridge between product stakeholders, engineering teams, and offshore testing resources.

Key Responsibilities & Objectives

• Offshore Collaboration: Work closely with offshore testing teams to ensure consistent quality standards and delivery across time zones.
• Automation Leadership: Create and maintain robust automation scripts during the sprint using Cypress and Playwright.
• AI Usage & Innovation: Drive innovation by integrating AI tools—including Gemini, GitHub Copilot, and Claude Code to accelerate test generation, optimize code reviews, and enhance quality engineering efficiency.
• Architectural Integration: Integrate with development teams to ensure testability, scalability, and performance are at the forefront of our complex payment architecture.
• Observability: Utilize Datadog to monitor system health, create quality metrics, and troubleshoot escalated support items.
• Agile Execution: Work as part of a Scrum team to automate and validate all stories specifically focusing on payment modals and UI prior to deployment.
• Defect Guarding: Report and guard against all product defects while engaging with stakeholders to ensure high-quality tokenization and capture workflows.
• Research: Continuously evolve quality practices by researching new testing tools and methodologies.

Requirements

• Education & Experience: BS in Computer Science or a related field with 7+ years of Quality Engineering experience in high-growth SaaS environments.
• Automation Mastery: Expert in Playwright and Cypress, with specific expertise in testing complex front-end components like payment modals and iframe integrations.
• Technical Stack: Strong hands-on experience with AWS (Lambdas, SQS, microservices) and Datadog for observability and system health monitoring.
• Coding & APIs: Proficient in TypeScript, Node.js, or C# for scalable frameworks; 5+ years of experience in REST API testing (Postman) and complex SQL data validation.
• AI & Innovation: Proven ability to leverage AI tools (Gemini, GitHub Copilot, Claude) to accelerate development cycles and optimize test maintenance.
• Leadership: Experienced in managing and mentoring offshore teams and navigating complex, distributed architectures and tokenization engines.
• Domain Expertise: Specialized in the Payments Industry, including PCI Compliance, payment capture workflows, and sensitive data handling.
• Process & Tools: Deep understanding of CI/CD pipelines, Agile (Scrum/Kanban), and advanced Jira defect management.
• Soft Skills: Analytical "break-fix" mindset with the ability to translate technical quality risks to non-technical stakeholders in fast-paced environments.
