About the role

  • We're looking for a Vendor Security Manager to join Sierra's Security team.
  • This is a hands-on role that requires both technical depth and strong judgment.
  • You'll help Sierra make informed trade-offs between speed, scale, and security in a business that moves fast and operates in regulated industries.

Responsibilities

  • Be the interface between Security and Sierra teams on everything vendor security related, drive risk conversations, and keep the program moving.
  • Own vendor security risk decisions and escalation paths end-to-end, including clear documentation of risk acceptance rationale, mitigation plans, and trade-offs.
  • Build and continuously improve the vendor security program methodology, tooling, risk tiering, monitoring, and response, scaling it intelligently as Sierra's vendor footprint grows.
  • Assess and manage security risk across Sierra's full third-party landscape, recognizing that vendors, strategic partners, and contractors carry distinct risk profiles and require tailored oversight.
  • A technology partner with deep API integration is a different security conversation than a SaaS tool or a contractor with scoped environment access - the program you build should reflect that.
  • Conduct deep, evidence-based security assessments across Sierra's vendor landscape SaaS providers, cloud and infrastructure partners, AI and model providers, and strategic suppliers including reviewing architectures, IAM configurations, access scopes, and vulnerability assessments.
  • Develop assessment frameworks for AI and model vendors that address risks specific to how these systems actually work including prompt data handling, training data practices, inference infrastructure access, and model supply chain integrity.
  • Develop and maintain a model provider oversight program that reflects Sierra's reality of working across a constellation of LLM and AI model vendors.
  • Think in blast radius. Understand what's reachable if they're compromised data flows, network adjacency, privilege scope, lateral movement paths and let that analysis drive technical controls and contractual requirements.
  • Build detection logic and automated alerting that fires when a vendor's security posture degrades lapsed certifications, exposed services, configuration drift, or new vulnerability disclosures so Sierra's response is proactive.
