Position Summary...

What you'll do...

About Team:

At Walmart, we prioritize innovation and data security. Our team is dedicated to maintaining a secure operating environment and preserving the trust of our customers, associates, and stakeholders. We combine a range of services and expertise to prevent fraud, detect threats, and manage digital risk and access. Our focus is on mitigating attack risks, securing cloud transformation, and fostering a culture of security and reliability within our team. This team is responsible for enterprise-scale AI security platforms, with a strong focus on Policy as Code, governance automation, and real-time enforcement.

What you'll do:

The Staff Engineer ensures continuous effectiveness of AI safety controls through automation, telemetry, and CI/CD safety gates. This role is the connective tissue between product-level implementations and platform-level enforcement.

• Business Context & Risk Surface Operates across multiple product teams to detect regressions and ensure consistent safety posture. Addresses risks like classifier drift, threshold creep, and undetected adversarial probing.
• Scope, Ownership & Decision Authority Owns automation frameworks, replay systems, and test harnesses; influences product-level safety tests. Can mandate additional testing for high-risk launches within platform governance rules.
• AI Security & Safety Responsibilities (Core) Implement CI/CD gates and automated regression tests for hallucination and jailbreak metrics. Create replay frameworks to safely reproduce customer-facing incidents and feed labeled data back into classifiers. Design alerting and escalation for emerging misuse trends.
• Platform / Architecture / Engineering Responsibilities Integrate automated tests with platform pipelines and ensure stable, reproducible test environments. Maintain datasets and test corpora for adversarial prompts and RAG poisoning.
• Governance, Compliance & Evidence Responsibilities Generate continuous evidence packages and dashboards for leadership; maintain audit logs for test runs.

What you'll bring:

• BE/Btech/MS/Mtech degree in Computer Science, Artificial Intelligence, Information Security, Information Technology, Engineering, Computer Information Systems, or related field with 8-15 years of work experience.
• Demonstrated understanding of AI- and LLM-specific threat models, including hallucination, prompt injection (direct and indirect), jailbreaks, data poisoning, model misuse, and over-reliance on probabilistic outputs.
• Working knowledge of the OWASP Top 10 for LLM Applications and the OWASP GenAI Security Project, including common failure modes such as insecure output handling, training data poisoning, model denial-of-service, and prompt injection.
• Familiarity with MITRE ATLAS™ (Adversarial Threat Landscape for AI Systems) and the ability to reason about attacker tactics such as model evasion, poisoning, extraction, abuse of autonomy, and adversarial probing.
• Experience designing or operating runtime AI safety controls, not limited to training-time alignment, including input/output validation, content moderation, PII detection, response steering, and last-mile enforcement.
• Understanding of distribution shift and out-of-distribution (OOD) risk in production AI systems and how these conditions lead to safety, reliability, and trust failures.
• Awareness of reward hacking and objective misalignment, and how poorly specified incentives can result in unsafe emergent behavior.
• Practical exposure to AI red-teaming and adversarial testing, including systematic discovery of failure modes and conversion of findings into automated regression tests.
• Understanding of agentic AI risks, including tool misuse, unintended action loops, escalation of autonomy, and the need for human-in-the-loop (HITL), sandboxing, and kill-switch mechanisms.
• Familiarity with evolving AI regulatory and legal expectations, including high-risk AI classifications, auditability, and technical evidence required for conformity assessments.
• Proven experience building automated safety testing and CI/CD pipelines for ML/LLM systems.
• Strong telemetry/observability background.
• Experience building replay frameworks and integrating red-team outputs into CI.
• Should be able to design safeguards for large-scale generative AI and autonomous systems. Should be able to tackle real-world AI risks such as hallucinations, misuse, and adversarial behavior. Should know to embed security, safety, and trust directly into AI platforms used globally. Should know to translate emerging AI regulations and ethical expectations into practical, production-grade engineering solutions. Able to work on problems where correctness, responsibility, and human impact truly matter.
