Citizenship Requirement: U.S. citizenship is required for this position due to work supporting federal government customers.
Location: Remote
Team: Engineering / Curated Images
Employment Type: Full-Time
About the Role
RapidFort is looking for a hands-on Senior Software Engineer to join our Curated Images team and help build, secure, and maintain production-ready container images at scale.
This role combines deep Linux engineering, vulnerability remediation, and software automation. You will own the container image lifecycle—from building minimal, reproducible images to analyzing and remediating CVEs, validating runtime compatibility, and automating ongoing maintenance and publishing.
You will work closely with engineering, infrastructure, and security teams to deliver secure, reliable images across Linux distributions and application stacks, including Python, Go, and Java. Success requires the ability to investigate package and dependency issues, implement fixes, and build automation that makes those fixes repeatable.
What You’ll Do
-
Design, build, and maintain minimal, hardened container images across Linux distributions and application runtimes.
-
Own end-to-end CVE remediation across OS packages, libraries, runtimes, and dependencies, including analysis, patching, rebuilding, and validation.
-
Troubleshoot complex package compatibility, dependency, build, and runtime issues while preserving application functionality.
-
Reduce image attack surface and size by removing unnecessary packages, binaries, and dependencies.
-
Build and improve automated pipelines for image builds, vulnerability scanning, remediation, testing, and publishing.
-
Develop tooling to manage image versioning, dependency updates, metadata, and release traceability.
-
Generate, validate, and maintain SBOMs to support software supply chain visibility and compliance.
-
Validate image functionality, reproducibility, and compatibility with Kubernetes and other containerized environments.
-
Collaborate with platform, infrastructure, and security teams to define image hardening standards and integrate curated images into development and deployment workflows.
-
Maintain clear documentation that helps developers adopt and use curated images.
