Role Summary

As a Senior Quality Engineer, you will design, implement, and maintain robust quality assurance strategies for complex, cloud‑native applications built on , , PostgreSQL, and AWS. You will lead test automation initiatives, ensure compliance with healthcare regulations, and embed quality practices into every stage of the software development lifecycle. You will collaborate closely with backend, frontend, DevOps, and product teams to deliver reliable, secure, performant, and resilient solutions — leveraging modern practices such as contract testing, observability validation, and AI‑assisted test generation.

What You'll Be Doing

• Develop and maintain automated test suites for backend services, RESTful APIs endpoints, and frontend integrations using Webdriver.IO, Jest, React Testing Library, Cypress, and Playwright.
• Implement contract testing (e.g., Pact) to ensure API compatibility across microservices and external integrations.
• Design and execute functional, integration, regression, performance, security, and resilience tests for applications and PostgreSQL database interactions (via Sequelize, ).
• Integrate automated tests into CI/CD pipelines using GitHub Actions and Docker, with continuous testing and shift‑left practices.
• Verify infrastructure deployments on AWS ECS Fargate, S3, RDS PostgreSQL, Secrets Manager, and CloudFormation for functional, non‑functional, and resilience requirements.
• Conduct chaos engineering experiments (e.g., AWS Fault Injection Simulator) to validate system recovery and fault tolerance.
• Collaborate with frontend teams using and Material‑UI to ensure smooth API consumption and UI quality.
• Apply accessibility testing aligned with WCAG 2.1/2.2 standards, ARIA roles, and automated audits (axe‑core), and validate Core Web Vitals for performance.
• Participate in Quality script code reviews with a focus on testability, maintainability, and quality.
• Ensure compliance with healthcare regulations (HIPAA, GDPR) and maintaining audit‑ready documentation.
• Leverage AI tools like GitHub Copilot for test development, AI‑driven test data generation, and intelligent defect clustering, while mentoring team members on responsible AI use.
• Validate observability by ensuring logs, metrics, and traces (e.g., Grafana, Prometheus, OpenTelemetry) meet operational and troubleshooting needs.

How You Will Succeed

• Proven expertise in designing and implementing scalable test automation frameworks for microservices, serverless, and event‑driven architectures.
• Strong understanding of system design principles to validate modular, robust, and maintainable solutions.
• Hands‑on experience with performance, security, resilience, and compliance testing in regulated environments.
• Skilled in defect analysis, root cause identification, and continuous improvement of test processes.
• Effective verbal and written communication skills.
• Ability to work collaboratively across backend, frontend, DevOps, and product teams, embracing TDD/BDD and pair testing practices.
• Mentorship of junior Quality Engineers.

What You Should Bring

• 5-8 years of professional experience in software quality engineering or test automation.

• Proficiency in automated testing tools (Webdriver.IO, Jest, React Testing Library, Cypress, Playwright).

• Experience testing backend services built with , , and PostgreSQL (Sequelize, ).

• Familiarity with Core Web Vitals and frontend performance testing techniques using Jmeter/Loadrunner/K6.
  
• Familiarity with cloud infrastructure testing (preferably AWS) and containerisation (Docker).
• Bachelor's degree in Computer Science, Computer Engineering, or related field.
• Knowledge of accessibility testing and WCAG standards.
• Exposure to REST API testing and contract testing.
• Experience in regulated industries (Life Sciences is a plus).

• Contributions to open‑source testing frameworks or QA communities.

• Awareness of observability tools and practices for monitoring and troubleshooting.

• Hands‑on experience with responsive design testing and cross‑browser compatibility validation.

Preferred Qualifications

• Experience with FeathersJS or similar frameworks for service‑layer testing.

• Knowledge of accessibility testing best practices and WCAG standards.

• Experience validating design systems such as Material‑UI, Ant Design.

• Exposure to Veeva QMS systems.
• Familiarity with modern build tools (Webpack, Vite, Babel, ESLint) for test integration and static analysis.
• Experience with chaos engineering and resilience validation.
• Familiarity with observability platforms (Grafana, Prometheus, OpenTelemetry).
• Experience in regulated industries (e.g., Life Sciences) is a bonus but not required.
• Contributions to open‑source testing frameworks or quality engineering communities.
