About RapidFort
RapidFort is the leader in end-to-end software supply chain security. Our platform helps organizations automatically identify, prioritize, and remediate vulnerabilities in containerized applications—without code changes or pipeline disruption. From curated near-zero-CVE container images to runtime Kubernetes protection, we enable teams to ship secure software faster. Backed by $42M in Series A funding and trusted by 100+ customers across defense, federal, and enterprise sectors, we’re defining the new standard for software attack surface management (SASM). We were recognized in the 2025 Gartner® Cool Vendors™ in Container Management report.
Role Summary
We’re looking for a hands-on Sr. QA Automation Engineer to own and evolve the Python-based test automation framework for our CLI-driven security platform. You’ll design and maintain end-to-end test suites that validate container image hardening, vulnerability scanning, SBOM generation, and compliance workflows across local, CI, and Kubernetes environments. This role demands strong ownership of test reliability, data-driven execution strategy, and clear documentation—paired with a genuine interest in security tooling.
What You’ll Work On

• Build and maintain robust automation suites using Python and pytest
• Convert manual/bash test plans into scalable, data-driven test frameworks (CSV/JSON/YAML)
• Design selective execution strategy (tags, ranges, run flags, grouping/sharding)
• Automate CLI command validation (exit codes, stdout/stderr expectations, failure semantics)
• Integrate and maintain test execution in CI/CD pipelines (GitHub Actions or equivalent)
• Validate container image hardening, scan outputs, and SBOM/RBOM generation across base distributions (Ubuntu, RHEL, Debian, Alpine)
• Manage and improve test artifacts/reporting (.html, .log, .json) for fast triage
• Troubleshoot environment/auth/configuration drift across runners and VMs
• Maintain high-quality handover docs, runbooks, and troubleshooting guides
• Partner with dev/platform teams to stabilize flaky tests and shorten feedback loops
