Job summary

Yahoo is seeking an experienced engineer to build AI-native security products for employees. You’ll ship agents, skills, and tools that make security work feel intuitive and frictionless.

As a Paranoids developer advocate, you’ll scale AI tooling, collaborate with engineers and product teams, and turn prototypes into durable, scalable solutions. You’ll own the tooling infrastructure and help define AI-native functions inside Yahoo’s security org.

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.
• 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.
• Advocate for the developer experience – Partner with the Paranoids engineers who own security solutions.
• Own our AI tooling infrastructure. Maintain and grow the team's AI tooling infrastructure, including skills, plugins, and internal agent marketplaces.
• Work closely with the user. 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.
• Document so others can build. Write clear docs, skill standards, and guides so your work is usable and extendable by the rest of the team.
