John "Jack" Pippett

I design secure systems for AI, telemetry, and the teams that depend on both.

Senior security engineer in Chandler, Arizona, aiming at AI security and application security architecture roles. Currently leading enterprise security data platform work, building independent AI security tools, and writing about how modern systems fail in the real world.

03 / Resume

A resume built around systems that actually run.

Centene Corporation

Security Data Platform Architecture Lead

Own architecture and delivery for Centene's Databricks-based AWS Security Data Lake and Databahn rollout, translating executive goals and vendor patterns into working endpoint telemetry systems across RBAC, disaster recovery, ingestion quality, and downstream analytics.

  • Drove project planning, architecture decisions, stakeholder alignment, and delivery sequencing for enterprise telemetry work spanning security engineering, vendor teams, and platform owners.
  • Led Databahn endpoint telemetry implementation for 70,000+ endpoints, compressing rollout timelines while preserving ingestion quality, access control, and recovery design.
  • Built the automation spine behind the program: GitLab CI/CD promotion gates, Tanium REST API workflows, Sysmon deployment, access reviews, and JIRA remediation pipelines.
M.S. Cybersecurity Capstone

Self-hosted AI agent infrastructure security research

Graduate capstone focused on the security architecture of local AI agent stacks: Ollama/LM Studio style runtimes, shell and environment access, tool permissions, prompt boundaries, and control-plane exposure.

Mapped the work against OWASP LLM Top 10, NIST AI RMF, and MITRE ATLAS, and independently identified indirect prompt injection through environment-variable exposure as a practical attack path.

Featured blog note

I Gave an LLM Shell Access to a Server. Here's What I Learned.

Spinning up a hardened VPS, handing an LLM shell access, and watching what sticks when AI agents meet real infrastructure.

LLM shell access lessons

The real iscooked.com post on agent hardening, prompt injection tests, OS-level controls, and why refusal behavior is not a security boundary.

Currently one real note, one tiny archive, and a suspicious amount of paper texture. More field reports soon.
