Build reusable libraries and guardrails to make secure implementation the default standard, reducing systemic risk across all engineering teams. Develop automated testing suites to identify and mitigate AI-specific vulnerabilities, such as prompt injection, indirect instruction following, and unsafe workspace mutations. Translate complex threat models into clear engineering requirements, production security checks, and launch criteria. Analyze production signals and incident reports to continuously harden the platform and optimize security architectures. Govern the safe use of internal tooling (coding agents, automation hooks, MCP integrations) to maintain a healthy balance between developer productivity and security. ### Qualifications Deep Engineering Expertise: 4-6+ years designing and securing complex software, with a proven ability to write and review production code cross-functionally. ### Architecture & Threat Analysis Strong judgment in evaluating data flows, permissions, and trust boundaries to spot structural weaknesses and redesign them for safety. ### Strategic Execution Proven ability to turn complex security risks into concrete, implementable product features. ### Automation-First Approach Focused on building reusable tools, secure libraries, and automated test patterns to solve problems permanently. Practical knowledge of prompt injection testing, AI red teaming, and evaluating model safety. Familiarity with enterprise SaaS requirements (e.g., audit logs, data residency, encryption, customer trust guarantees). Background in developing internal tools, CI pipelines, MCP integrations, or coding-agent guardrails. Active participation in the security community via open-source work, vulnerability write-ups, or conference talks. #LI-BL1 Compensation Disclosure The compensation offered for this position will depend on qualifications, experience, and work location.
