Senior Security Engineer - Cloud & AI Platform

Role Overview

What you’ll own

AI and agent security

Threat model new AI agent features before launch: direct and indirect prompt injection, jailbreaks, data exfiltration through agent outputs, and over-privileged tool use

Design guardrails for agentic workflows: least-privilege tool and connector scopes, human-in-the-loop approvals for high-risk actions, and output filtering

Enforce tenant and data isolation across retrieval (RAG), context stores, and model calls, so no customer’s data leaks into another’s context

Secure the AI supply chain: model and provider vetting, third-party MCP servers and connectors, prompt and config versioning

Run AI red-team exercises and build automated adversarial tests (prompt injection suites) into CI

Cloud and platform security

Security baselines for Kubernetes and cloud infrastructure: RBAC, network policies, workload identity, secrets management, per-tenant network isolation

Security in CI/CD: IaC scanning, SAST and dependency scanning, policy-as-code guardrails

What you’ll contribute to

AI-aware detection with our current technology and tooling: logging prompts, tool calls and agent actions, and alerting on anomalous agent behavior

Partner with the Security & Compliance Lead on technical controls and evidence for SOC 2 Type II, ISO 27001, HIPAA and ISO 42001, plus the NIST AI RMF

Must-haves

5+ years in cloud security, application security, or DevSecOps (GCP/Azure Preferred)

Deep hands-on Kubernetes and cloud security experience

Security automation with IaC (Terraform/Helm) and Python or Bash.

A working understanding of LLM application risks (OWASP Top 10 for LLM Applications) and how agentic systems fail

Comfortable influencing engineers without formal authority

Nice-to-haves

Hands-on experience securing LLM, RAG, or agentic systems in production

AI red teaming, or familiarity with MITRE ATLAS

CNAPP/CSPM tooling, SIEM/detection engineering

Contributions to AI security research, open-source tools, or CTFs
