Job summary

Yahoo is seeking a Paranoids Cyber Experience Engineer (Finance) to build AI-native security experiences for employees. You will ship agents, skills, and tools that make security tasks faster, clearer, and more engaging, while scaling AI tooling for a small team to operate like a larger one.

You will serve as a developer advocate, partnering with engineers, shaping developer experience, and documenting designs so others can build.

Qualifications

• 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). Prior Linear use is a plus, not a requirement.
• Exposure to or curiosity about security work.

Responsibilities

• Build employee-facing products using AI.
• Advocate for the developer experience
