Open Source Software Security Engineer – Software Supply Chain

• Define policies, standards, and control requirements for approved open source usage, dependency hygiene, SBOM generation, secure package sourcing, and software supply chain risk management


• Establish OSS intake, approval, tracking, ownership, version management, vulnerability remediation, end-of-life retirement, and exception governance processes


• Design and implement automated CI/CD security gates for curated OSS usage, dependency scanning, license checks, artifact validation, provenance controls, build-time enforcement, and policy-based blocking


• Identify and reduce risks from vulnerable dependencies, malicious packages, dependency confusion, typosquatting, compromised maintainers, insecure build artifacts, and unauthorized package sources


• Establish controls for trusted package sources, dependency provenance, build integrity, artifact signing, repository hygiene, tamper resistance, and secure release practices


• Establish capabilities to detect, assess, and respond to open source supply chain threats, zero-day vulnerabilities, compromised dependencies, and security incidents


• Support deployment, tuning, and integration of software composition analysis, SBOM, package repository, vulnerability management, and developer workflow tools


• Develop reporting on OSS risk posture, remediation velocity, policy exceptions, preventative-control adoption, and high-risk dependency reduction


• Create guidance, playbooks, reusable patterns, and consultation models for engineering teams


• Partner with CI/CD, DevSecOps, application security, engineering, platform, and risk teams

Requirements

• Bachelor’s degree or equivalent education, training, and work-related experience


• Minimum of 5 years of experience in security engineering or related cybersecurity roles


• Advanced knowledge in cybersecurity principles, theories, and concepts


• Proven experience in software development lifecycle security practices


• Advanced knowledge of threat modeling, security testing, and penetration testing


• Experience implementing and managing complex information security technologies


• Advanced cybersecurity certifications (e.g., CISSP, CISM, CEH, GIAC) (preferred)


• Experience with security automation, orchestration, and advanced threat detection tools (preferred)


• Familiarity with emerging cybersecurity technologies, industry trends, and strategic risk management (preferred)


• Experience in application security, software supply chain security, DevSecOps, vulnerability management, secure engineering, or related cybersecurity functions (preferred)


• Strong understanding of open source software governance, dependency management, SBOM, SCA, secure SDLC, CI/CD pipelines, and software supply chain threats (preferred)


• Working knowledge of OWASP, NIST SSDF, SLSA, and related secure development guidance (preferred)


• Experience applying software supply chain security practices, including provenance, build integrity, artifact signing, secure package repositories, dependency trust, and CI/CD pipeline hardening (preferred)


• Hands-on experience with CI/CD platforms, source code management, package managers, build systems, artifact repositories, and developer workflows (preferred)


• Experience with scripting or automation using Python, PowerShell, Bash, or similar (preferred)


• Ability to partner with engineering, platform, cloud, risk, audit, and compliance stakeholders (preferred)


• Ability to translate technical risk into executive-ready reporting, measurable outcomes, and actionable remediation plans (preferred)


• English language fluency required


• Must work onsite, office-centric, 5 days a week

Demonstrates advanced knowledge in cybersecurity principles, threat modeling, and software supply chain security, with proven experience in implementing security practices throughout the software development lifecycle.
