• Implement and maintain backup, recovery, and business continuity solutions using Rubrik or similar platforms.
• Engineer identity and access management solutions using Okta and/or Azure AD (Entra), including SSO, MFA, conditional access, and lifecycle automation.
• Troubleshoot complex, escalated infrastructure issues and lead root-cause analysis to prevent recurrence.
• Provide technical direction, code/configuration reviews, and mentoring to other infrastructure team members.
• Collaborate with security, application, and business teams to ensure infrastructure aligns with operational and security requirements.

What You Bring

• Strong hands-on experience as a senior infrastructure or systems engineer.
• Deep technical expertise across Windows infrastructure, networking, virtualization, cloud platforms, and identity management.
• Experience serving as a technical lead or senior engineer, guiding others through expertise rather than formal management.
• A problem-solving mindset with strong ownership of systems and outcomes.
• Ability to communicate technical decisions clearly to both engineers and stakeholders.
