Required Skills: •You must be work authorized in the United States without the need for employer sponsorship. •The Impact You Will Have •Architect and build the platforms, guardrails, and reusable frameworks that let Ridgeline adopt AI safely at scale, driving secure-by-default patterns that close entire risk classes before systems are built. •Find and mitigate the AI-specific risks that generic tooling misses: prompt injection, model input/output sanitization, data leakage, and trust-boundary violations across AI-powered features and agents. •Secure agentic and tool-use systems, including function/tool calling and MCP server integrations, with clear trust boundaries and least-privilege patterns for AI agents. •Establish and operate guardrails for internal AI developer tooling (e.g., Claude Code, Cursor, etc.) that let engineering move fast without sacrificing security. •Threat model new AI features and infrastructure to define security requirements before they are built, partnering with engineering and product teams so the secure path is also the easy one. •Build AI-augmented security tooling and pipelines that extend the team's capacity while keeping false positives low enough that engineering trusts the results. Qualifications: •Applied hands-on capability in prompt-injection prevention, LLM input/output sanitization, or agent / tool-use / MCP security. •Contributions to AI security research, open source security tooling, or emerging AI security standards. •Operational familiarity with cloud-native security at scale (AWS) and infrastructure-as-code (e.g., Terraform).
