Software Engineer (Security)

About Us

At Cloudflare, we're on a mission to help build a better Internet. We protect and accelerate any Internet application online without adding hardware, installing software, or changing a line of code.

As a Senior Security AI Engineer, you will be the technical architect for our Agentic AI roadmap. Your mission is to move beyond simple automation scripts and build a fleet of 'AI Team Members',intelligent helper agents that execute complex security algorithms, process flows, and assessment logic.

Responsibilities

• Agent Architecture: Design and deploy multi-agent systems that follow complex security algorithms and assessment flows to automate manual SOC and Assurance tasks.

• Skill Engineering: Standardize agent capabilities by creating and maintaining skills.md files and specialized Markdown documentation that define agentic personas and execution boundaries.

• Workflow Training: Train and fine-tune LLMs to function as 'helper agents' capable of executing autonomous AI workflows as integral members of the Security Engineering team.

• Infrastructure as Agents: Utilize Cloudflare Workers, Vectorize, and AI Gateway to build serverless, low-latency agentic architectures for real-time traffic analysis and remediation.

• Autonomous Assessment: Build and scale the engine for autonomous vendor security reviews and M&A assessments, transforming qualitative data into quantitative risk insights.

Requirements

• Experience: 4+ years in Information Security or Software Engineering, with at least 1+ years focused on AI Engineering, Agentic AI, or Advanced Automation using Opencode

• AI Expertise: Deep understanding of LLM orchestration, prompt engineering, and building agentic loops (e.g., LangChain, AutoGen, or custom frameworks).

• Agent Development: Proven ability to create agents from structured definitions (skills.md) and automate tasks that follow strict process/algorithmic flows.

• Cloudflare Ecosystem: Expert knowledge of Cloudflare Workers, KV, Durable Objects, and R2. Experience with Cloudflare AI tools is a significant plus.

• Languages: Mastery of Windsurf, Opencode or Rust.

• Security Domain: Strong grasp of Cyber Security fundamentals, including SIEM/SOAR logic, UEBA, and risk assessment frameworks.

Preferred Qualifications

• Experience building custom Agentic AI solutions that have replaced enterprise-grade 3rd party security software.

• Background in M&A Security Due Diligence or Vendor Risk Management automation.

• Prior experience building edge-based security products or AI-driven log-push integrations.

• Certifications: CISSP or specialized AI/Machine Learning certifications.
