Platform Engineer - GitHub Advanced Security

As a Platform/Staff Security Engineer, your role is to bridge the gap between security standards, developer velocity, and the emerging world of AI-assisted engineering. By championing the GitHub Advanced Security (GHAS) ecosystem and Copilot’s autonomous agent capabilities, you will empower our engineering community to deliver resilient software through seamless automation, custom AI guardrails, and collaborative mentorship.What You Will Do: Ecosystem Optimization: Lead the strategic evolution of the GitHub Advanced Security environment and GitHub Copilot configuration, ensuring AI and security tools are tuned for maximum accuracy and minimal developer friction. Secure AI Orchestration: Design and govern the use of Copilot autonomous agents (e.g., Copilot coding agents), ensuring that AI-generated code and pull requests meet enterprise security and quality standards before they reach human review. Seamless Guardrails: Design and deploy automated scanning (CodeQL, Secrets, and Dependencies) that integrates natively into CI/CD workflows, leveraging AI-driven autofix capabilities to accelerate remediation. Technical Advocacy: Act as a high-level partner for development teams, helping them navigate complex security findings and providing the technical clarity needed to securely adopt agentic workflows. Pattern Recognition & AI Guidance: Identify recurring security trends and develop custom repository instructions to guide Copilot agents toward Wellmark’s specific coding standards and security patterns. Risk Intelligence: Establish the metrics required to move our security posture from reactive to proactive, monitoring the impact of AI-assisted development on code quality and security debt.
