Candidates need to meet the following qualifications:
- 3+ years of hands-on testing experience in DBMS, cloud services, storage, or operating systems
- Strong working knowledge of Docker, Linux, and network security fundamentals
- Experience with or strong interest in security testing, including CVE triage, dependency scanning, Docker image scanning with tools such as Grype or Trivy, authentication, authorization, RBAC, OAuth, TLS, FIPS, secrets handling, and security-hardened systems
- Excellent knowledge of Python, C++ and bash scripting
- Excellent coding skills and ability to write clean, efficient test code
- Expert at designing enterprise-level functional tests for cloud services, client libraries, or service APIs
- Experienced in using modern CI/CD systems like GitHub Actions
- Tenacious at figuring out ways to break software and systematic in documenting bugs
- Excellent discipline to follow test processes
- Capable of working independently with minimal supervision
