Backblaze is seeking a Senior AI Security Engineer to design and implement safeguards for internal AI usage, with a focus on agentic systems, developer protection, and runtime security.

What You’ll Do

Agentic AI Safeguards
- Architect and implement guardrails for tool-using AI systems, including:
- Tool access controls and allowlists
- Context and memory isolation
- Step-level validation of agent actions
- Apply mitigations aligned to the OWASP Agentic AI Top 10 (e.g., prompt injection, unsafe tool use, data leakage, excessive autonomy).

Runtime Security Controls
- Build enforcement mechanisms that govern AI behavior at execution time:
- Interceptors, proxies, or middleware for tool/API calls
- Policy decision and enforcement layers
- Rate limits, execution bounds, and kill-switches
- Prevent unsafe or unauthorized actions initiated by AI systems.

Non-Human Identity (NHI)
- Design and implement identity and access controls for agents and automation, including:
- Short-lived credentials and scoped permissions
- Clear separation between human and non-human access




- Strong binding of identity to task context and execution
- Ensure all AI actions are attributable and auditable.

Observability & Detection
- Implement logging and tracing for AI activity:
- Prompts, tool usage, and decision flows
- Build detection capabilities using:
- Behavioral baselining and anomaly detection techniques
- Identify and alert on:
- Abnormal tool usage
- Suspicious prompt patterns
- Unexpected data access

Threat Modeling (MAESTRO)
- Perform agentic system threat modeling using MAESTRO, including:
- Mapping agent capabilities, trust boundaries, and attack paths
- Modeling misuse and adversarial scenarios
- Translate findings into practical safeguards and detection logic.

Developer Safeguards
- Protect developers using AI tools by:
- Preventing sensitive data exposure
- Validating AI-generated code and actions
- Constraining unsafe automation
- Enable safe usage of AI‑assisted developm
