Staff Infrastructure Security Engineer

We are seeking a highly skilled Staff Infrastructure Security Engineer to architect, deploy, and operationalize the foundational security services that will underpin our shift to a Zero Trust model. In this strategic role, you will define and establish the "roots of trust" for our organization, serving as a technical leader in Secrets Management and Identity architecture. While your immediate focus is to serve as the Subject Matter Expert (SME) driving our enterprise Hashi Corp Vault platform from Proof-of-Concept (PoC) to global production readiness, your long-term scope is far broader.

You will be responsible for evolving our credentials management strategy, onboarding engineering teams to secure self-service workflows, and designing scalable trust patterns across our hybrid multi-cloud environment.

• Strategic Architecture & Governance
• Zero Trust Architecture:
  Architect a highly available, disaster-resilient, and scalable multi-cluster secrets management platform that serves as the foundation for the organization’s Zero Trust strategy.
• Technical Leadership:
  Drive consensus across Cloud Engineering, Dev Ops, and SRE teams to define standardized secret management workflows and integrate security patterns into the SDLC.
• Compliance & Governance:
  Ensure the platform design meets rigorous internal policies and external compliance frameworks (e.g., SOX, ISO 27001).
• Policy as Code:
  Design and implement advanced governance controls, including Sentinel Policy as Code, to automate security guardrails and access decisions.
• Platform Engineering & Implementation
• Infrastructure as Code (IaC):
  Lead the engineering of the Vault infrastructure using Terraform, ensuring all deployments are reproducible, version-controlled, and automated.
• Identity Integration:
  Architect the integration between the secrets platform, Identity Providers (Okta), and workload identities (Kubernetes Service Accounts) to establish robust machine-to-machine authentication.
• Advanced Secrets Capabilities:
  Configure and tune essential secrets engines (KV, Transit, KMIP) and Enterprise features (Performance Replication, Seal automation) to support diverse engineering use cases.
• Operational Excellence & Developer Enablement
• Vault as a Service (VaaS):
  Operationalize the platform by building self-service mechanisms, distinct "paved road" onboarding procedures, and documentation that allows engineering teams to easily consume security services.
• Observability:
  Implement comprehensive monitoring, alerting, and audit logging to ensure platform health, provide visibility into usage patterns, and satisfy audit requirements.
• Lifecycle Management:
  Own the full operational lifecycle of the production environment, including patching, version upgrades, backup/restore procedures, and incident response runbooks.

• 6+ years (or equivalent) hands‑on experience in cloud security, Dev Ops, or infrastructure engineering.
• Deep expertise and proven track record deploying and managing Hashi Corp Vault in an enterprise environment (experience with the Enterprise edition is highly preferred).
• Expert‑level knowledge of Secrets Management, X.509 PKI (Public Key Infrastructure), Certificate Authority Operations, and Cryptography concepts.
• Strong experience with Google Cloud Platform (GCP) and cloud native identity and access management (IAM).
• Proficiency with Infrastructure as Code (IaC) tools, especially Terraform, for automating the deployment and configuration of Vault and its dependent infrastructure.

• Fluent in at least one programming language (ideally Go or Python).
• Demonstrable experience with Kubernetes and container security…
