Summary

We are hiring a Senior QA Engineer (Contractor) to join a high-performing engineering team building real-time, high-availability payment systems. This is a hands-on role requiring strong technical depth, ownership, and the ability to improve quality from day one.

• The ideal candidate will bring strong experience across test automation, API testing, UI testing, integration testing, performance testing, SQL validation, mocking/stubbing, CI/CD, and production-quality engineering practices. They should be able to clearly demonstrate their technical decision-making with practical examples.

Responsibilities

• Design, develop, and maintain scalable automated test frameworks and test suites for web, API, and service-based applications.
• Own testing activities across the full SDLC: requirements analysis → test design → automation → execution → defect management → release validation.
• Build and maintain robust automated regression coverage for API, integration, and end-to-end workflows.
• Validate quality in low-latency, highly available systems with a strong focus on stability, accuracy, and production readiness.
• Collaborate closely with developers, product teams, DevOps, and other QA engineers to ensure quality outcomes across multiple teams.
• Drive defects and quality issues to resolution with a strong ownership mindset.
• Contribute to test strategy, quality standards, release confidence, and continuous improvement initiatives.
• Review applications and test coverage proactively to identify quality gaps, flaky tests, test data issues, performance risks, and automation opportunities.
• Support production validation, issue triage, and root cause analysis where needed.
