Git Hub is transforming how the world builds secure software, and we are looking for a Product Security Engineer III to join our Product Security Engineering team. This is a hands-on engineering role focused on building internal security platforms, tooling, and automation that protect Git Hub's products at scale.

You will design, build, and maintain the systems that make Git Hub's security program run: static analysis pipelines, agentic security tooling, supply chain defenses, and developer-integrated security controls. The ideal candidate is a strong software engineer who is passionate about application security and wants to solve security problems through code. You will partner closely with product and engineering teams to ship security improvements that scale with the organization.

• Design, build, and maintain security tooling and automation, including static analysis pipelines, secret scanning workflows, and dependency analysis systems.
• Contribute to scalable solutions that reduce recurring vulnerability patterns, focusing on preventing classes of vulnerabilities rather than addressing individual instances.
• Build and improve agentic security tooling for automated triage, assessment, and remediation of security findings.
• Develop security libraries, CI/CD integrations, and developer-facing tools that make the secure path the default path for engineering teams.
• Contribute to supply chain security defenses, building detection and prevention systems that protect Git Hub's software supply chain.
• Collaborate with teams across the organization to address security risks and define new requirements and feature sets.
• Analyze key metrics and KPIs to identify trends in security issues, evaluate the effectiveness of security tooling and automation, and recommend improvements to address gaps in measurement.

Required Qualifications:

• 5+ years experience in security analysis, security research, cyber security, security engineering, or relevant area
• OR Associate's Degree in a related field AND 4+ years experience in security analysis, security research, cyber security, security engineering, or relevant area
• OR Bachelor's Degree in a related field AND 3+ years experience in security analysis, security research, cyber security, security engineering, or relevant area
• OR Master's Degree in a related field AND 1+ year(s) experience in security analysis, security research, cyber security, security engineering, or relevant area
• OR equivalent experience.
• 1+ year(s) of experience in building security tooling and implementing solutions in complex environments.
• 3+ years experience programming in at least 2 of these 3 coding languages:
  Ruby, Go, Python.

Preferred Qualifications:

• Experience with static analysis tools (SAST/DAST), code scanning frameworks, or custom rule authoring.
• Experience building agentic or AI-driven security tooling (e.g., automated triage, classification, or remediation).
• Familiarity with software supply chain security concepts and tooling.
• Experience working in large-scale monolith or distributed service codebases.
• Familiarity with Git Hub's products, platform, and developer ecosystem.
• Strong expertise in security principles, including the Security Development Lifecycle (SDL), and experience in vulnerability management.
