In this challenging yet rewarding role, you are an integral part of what brings our Company's mission to life. You must have the following required skills, certifications and demonstrated experience in and/or with:

  • Testing applications deployed on AWS (at least 1–2 major services such as EC2, S3, RDS, Lambda, API Gateway, ECS/EKS, or CloudFront)
  • Strong knowledge of QA fundamentals: test planning, test case design, defect lifecycle, regression testing, risk-based testing.
  • Test automation experience using one or more frameworks/languages (e.g., Python + pytest, Java + JUnit/TestNG, JavaScript/TypeScript + Playwright/Cypress/Selenium).
  • Writing and maintaining automated tests integrated into CI/CD pipelines (e.g., GitHub Actions, Jenkins, GitLab CI, or AWS CodePipeline/CodeBuild).
  • Version control (Git) and standard SDLC practices (Agile/Scrum).
  • Strong defect isolation and debugging skills; can collaborate with developers/DevOps to reproduce issues and validate fixes.
Highly Desired Qualifications

  • Testing distributed systems/microservices, including asynchronous/event-driven flows (e.g., SQS/SNS/EventBridge/Kinesis).
  • Infrastructure-as-Code exposure (Terraform, AWS CloudFormation, AWS or CDK) and ability to validate deployments or config changes.
  • Container platforms and orchestration (Docker, ECS, or EKS/Kubernetes) and testing containerized workloads.
  • Testing APIs (REST/JSON) using tools such as Postman, curl, or similar; ability to validate status codes, payloads, headers, auth, and error handling.
  • Logging or monitoring for troubleshooting test failures (e.g., CloudWatch logs/metrics; or Splunk/ELK).
  • Performance and reliability testing experience (load/stress/soak) using tools such as k6, JMeter, Gatling, Locust; familiarity with scaling behaviors in AWS.
  • Test data management in cloud environments (synthetic data, masking, seeding, or ephemeral environments).
  • AWS certification (Cloud Practitioner, Developer Associate, SysOps Associate, or DevOps Engineer).
  • Working with complex, high security, regulated environments.
  • Excellent written and verbal communication skills with both technical and non-technical audiences.
  • Linux Operating Systems
  • Working effectively in high-performing, cross-functional teams with multiple concurrent projects.
  • Working directly with stakeholders to gather requirements, understand needs, and translate them into technical solutions with minimal oversight.
  • Self-directed work with a strong ownership mentality and commitment to code quality, testing, and documentation.
  • Context-switching between projects and systems as priorities demand.

  • Highly Competitive Salary : Recognizing and rewarding your expertise and contributions.
  • Generous Paid Time Off : Providing ample time for rest, relaxation, and personal pursuits.
  • Dedicated Training Budget : Supporting continuous learning and professional development.
  • 100% Employer-Covered Family Vision, Dental, and Health Insurance : Ensuring comprehensive health coverage for you and your family.
