AI-Powered Security Experience Engineer

Yahoo Holdings Inc.; Reston (VA); Hybrid; USD 111,000 - 231,000; Full time

Job summary

Yahoo Holdings Inc. is seeking an engineer to build AI-native security experiences for employees. This hands-on role on a small team will ship employee-facing AI products: agents, skills, and tools to reduce friction in security tasks.

You'll scale tooling, and influence where you don't own the solution. You'll work with Paranoids, advocate for developer experience, and turn prototypes into durable products.

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. Represent the developer user group in those conversations and push for designs that make requirements easier to meet, not just easier to ship.
• Own our AI tooling infrastructure. 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.
• 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.
