Key Responsibilities

Policy Engine & API Development

• Design and implement high-performance APIs for downstream systems to consume policy information and access decisions.
• Develop resilient synchronization processes between the core policy engine and individual third-party/vendor security products.
• Support application and infrastructure onboarding, ensuring high data quality and driving automated issue remediation.
• Establish operational monitoring, structured logging, proactive alerting, and performance reporting using tools like Splunk.

Vulnerability Management & System Security

• Implement security fixes and enhancements for the internally developed host-based firewall policy and control system.
• Review, triage, and remediate security vulnerabilities across codebases, dependencies, and build configurations identified via code scanning tools.
• Enforce Secure Coding Practices and validate security patches through thorough unit, integration, and regression testing.
• Support production deployment cycles, change management procedures, and maintain accurate technical documentation and release notes.

Engineering & AI Integration

• Apply modern software engineering methodologies (TDD, Agile/Scrum) to build clean, maintainable, and well-tested code.
• Leverage open-source AI frameworks (PyTorch, LangChain, MCP, RAG) to optimize internal workflows and support intelligent automation initiatives.
