Paranoids Cyber Experience Engineer

Yahoo is a trusted online services and advertising company whose Paranoids information security team works to keep employees and consumers safe online. The Cyber Experience Engineer will build and ship AI-native, employee-facing security products, scale AI tooling infrastructure, and advocate for developer-friendly security solutions. The role also involves evaluating AI outputs, collaborating with users and engineering teams, and documenting systems for reuse.

Responsibilities:

• Design, build, and ship agents, skills, and tools that help Yahoo employees navigate security without friction. Take a concept to a working prototype fast, then iterate with real users
• Partner with the Paranoids engineers who own security solutions. Represent the developer user group in those conversations and push for designs that make requirements easier to meet, not just easier to ship
• Maintain and grow the team's AI tooling infrastructure, including skills, plugins, and internal agent marketplaces, while evaluating and refining AI-generated outputs for reliability and accuracy
• Build for our audience segments, from general employees to developers to call center agents. Watch how people actually use what you ship and let that drive the next version
• Write clear docs, skill standards, and guides so your work is usable and extendable by the rest of the team

Requirements:

• Hands-on experience building with LLMs and agentic AI tools, including prompt engineering, agent orchestration, and authoring reusable skills/agents
• Proficient in a programming language like Python or TypeScript
• Experience integrating APIs and Model Context Protocols (MCPs) to connect distributed systems and automate operational tasks
• Proven track record of evaluating, validating, and refining AI-generated outputs for accuracy, safety, and security
• Comfortable building lightweight UIs (HTML/CSS, JavaScript) for the products you ship
• Familiarity with MySQL for database querying and management
• Comfortable partnering with engineering teams you don't sit on, and making a clear, evidence-based case for the user
• Comfortable with Git and GitHub as the source of truth for code and content
• Clear technical writing, the kind that lets someone else use or extend what you built
• Comfortable in modern collaboration tools (Linear, Jira, Google Workspace)
• Exposure to or curiosity about security work
• Prior Linear use is a plus, not a requirement
