Description:

Principal Security Engineer (Architecture focus)

We're looking for a senior-level security professional to lead the design and evolution of enterprise security architecture across a complex, primarily on-prem environment with growing cloud adoption. This role will define security standards, guide engineering teams, and ensure the organization's infrastructure, applications, and data are protected against modern threats.

This is a high-impact position working cross-functionally with infrastructure, application development, and leadership teams to embed security into every layer of the technology stack.

What You'll Do

  • Own and drive the enterprise security architecture strategy
  • Design secure solutions across infrastructure, applications, identity, and cloud platforms
  • Partner with engineering and DevOps teams to integrate security into system design and deployment pipelines
  • Establish and enforce security standards, frameworks, and best practices
  • Lead threat modeling, risk assessments, and architecture reviews
  • Evaluate and recommend security tools and technologies
  • Provide technical leadership and mentorship to security and engineering teams
  • Act as a key advisor to leadership on security posture, risk, and investments
  • Support incident response and remediation from an architectural standpoint

What They're Looking For

  • 8+ years in cybersecurity, with strong focus on architecture and design

Deep experience across:

  • Network and infrastructure security
  • Identity and access management (AD, Azure AD / Entra ID)
  • Application and API security
  • Cloud security (AWS and/or Azure)

Strong understanding of:

  • Security frameworks (NIST, CIS, ISO)
  • Zero Trust concepts
  • Threat modeling and risk management
  • Experience working in hybrid environments (on-prem + cloud)
  • Ability to influence teams without direct authority
  • Strong communication skills—this is not a heads-down role

Nice to Have

  • Experience in heavily regulated industries
  • Familiarity with tools like SIEM, EDR, vulnerability management platforms
  • Relevant certifications (CISSP, SABSA, TOGAF, etc.)
