You will join Walmart’s AI Security Team, which develops security frameworks to protect enterprise AI assets and address risks involving generative AI and agentic workflows, including prompt injection and model supply-chain challenges. The team uses systems engineering, cloud migration, continuous integration, and software development to build secure, scalable infrastructure and protect organizational resources while enabling AI solutions.

The position is based at 805 SE Moberly Ln., Bentonville, Arkansas. The annual salary range is $130,000 to $260,000, with additional annual or quarterly performance bonuses and, for certain positions, stock.

Requirements

• Python programming skills for securing agent execution environments, validating and sanitizing structured model outputs and tool calls, or handling arbitrary execution in dynamic evaluation workflows.
• Experience integrating automated AI security testing, including prompt-injection testing, model scanning, and dependency-vulnerability checks.
• Experience isolating autonomous agent runtimes and untrusted tool executions using hardened container environments.
• Knowledge of best practices for auditing, tracking, and enforcing peer review of system prompts, agent tool schemas, and policy-as-code to prevent prompt tampering.
• Proficiency in defining immutable, secure Linux environments for AI workloads and configuring runtime guardrails and OS-level sandboxing.
• Knowledge of multi-agent design patterns, state management, and blast-radius containment to ensure agents operate within deterministic boundaries.
• Option 1 minimum qualification: Bachelor’s degree in computer science, information technology, engineering, information systems, cybersecurity, or a related area, and 6 years of experience in systems and infrastructure engineering or a related area at a technology, retail, or data-driven company.
