Senior QA Engineer

Why PayNet / Why Now

• Strengthen quality controls as participant onboarding platforms scale in volume, integrations, and change frequency
• Prevent production defects and onboarding failures through stronger automation and earlier testing
• Embed quality and risk thinking into Improving Participant Onboarding journey (IPOJ) delivery as release velocity increases
• Ensure onboarding journeys remain reliable, secure, and usable for all participants

TL;DR

• Own automation-led quality assurance for IPOJ onboarding platforms
• Build and maintain testing frameworks embedded into CI/CD pipelines
• Act as senior QA authority and mentor within the delivery team
• Reduce production risk through performance, security, and scalability testing

Why This Role Matters

• Ensures participant onboarding journeys remain reliable, secure, and seamless, directly impacting participant experience and trust in PayNet's ecosystem.
• Prevents production defects and onboarding failures through robust automation, performance testing, and early risk detection.
• Supports faster delivery cycles by embedding quality assurance into CI/CD pipelines without compromising system stability.
• Strengthens platform scalability and resilience as onboarding volumes, integrations, and business requirements continue to grow.
• Promotes a quality-first engineering culture by driving testing best practices, mentoring team members, and continuously improving QA processes.

What You Will Actually Do

• Design, build, and maintain scalable test automation frameworks to improve test coverage, efficiency, and release quality.
• Define and execute testing strategies across functional, API, performance, security, scalability, and usability testing.
• Integrate automated tests into CI/CD pipelines and continuously optimize testing workflows for faster, more reliable releases.
• Investigate, troubleshoot, and resolve complex quality issues while identifying risks and implementing effective mitigation plans.
• Collaborate with developers, product managers, and stakeholders while mentoring junior QA engineers and promoting a quality-first culture

Examples of This Role in Practice

• Automate regression, API, and performance test suites to detect defects early and prevent onboarding disruptions before production releases.
• Collaborate with developers to improve the testability and quality of new onboarding features through automated testing and quality reviews.
• Identify performance, scalability, and reliability risks ahead of major releases and recommend mitigation strategies.
• Enhance CI/CD pipelines by integrating automated quality checks to provide faster and more reliable feedback to engineering teams.
• Mentor junior QA engineers, review test automation scripts, and drive the adoption of best practices across the delivery team.
