• Hands-on experience with cloud platforms (GCP or AWS), including containerized and serverless services.
• Experience testing REST APIs, asynchronous workflows, and multi-tier applications.
• Strong analytical, troubleshooting, and collaboration skills in fast-paced environments.

Experience we consider a plus:

• Experience with CI/CD tools (GitHub Actions, Jenkins, GCP Cloud Build).
• Exposure to commerce systems, payments, or transaction workflows.
• Experience with performance, load, and scalability testing for high-traffic systems.
• Familiarity with contract testing (Pact), Kafka, API security, or SSO standards (SAML, OIDC).

How you’ll benefit:

• Attractive Discretionary Time Off
• Private Medical Insurance with optional dependent coverage
