  • Serve as a technical resource for our rapidly scaling business, providing strategic guidance on the evolution and optimization of our IT systems and infrastructure.
  • Champion cross-team knowledge sharing by developing and maintaining comprehensive, high-quality IT documentation and playbooks.
  • Continuously evaluate the environment for strategic gaps and opportunities, driving initiatives to enhance system maturity and security posture, and proactively identifying and automating complex manual processes.
  • Evaluate emerging technologies and industry best practices, providing insightful recommendations for adoption and integration to enhance our IT capabilities.

What We’re Looking For:

  • 7+ years of extensive experience designing, implementing, and administering a broad spectrum of enterprise-level SaaS applications in a cloud-first environment.
  • Deep technical mastery of our primary tech stack: Okta (including advanced features and integrations), Google Workspace, Slack, Zoom, and the Atlassian suite (with significant experience in Jira Service Desk and Software automation, custom workflows, and advanced administration).
  • 5+ years of hands-on experience with Okta Workflows and other enterprise-grade iPaaS platforms (e.g., Workato, Zapier, BetterCloud), including designing and implementing complex integrations.
  • Expert-level understanding and practical application of advanced IAM concepts (SSO, SWA, SAML, JIT, SCIM, OIDC, OAuth, RBAC, ABAC), including designing and troubleshooting complex authentication and authorization flows.
  • Experience working with APIs for integration, automation, and data manipulation.
  • Advanced scripting proficiency for automation, monitoring, and alerting systems (e.g., Python, Bash, PowerShell, JavaScript, GAM), with experience in developing robust, scalable scripts.
  • Exceptional analytical and complex problem-solving skills, coupled with a deep understanding of IT operations, incident management, and change management best practices.
  • Demonstrated ability to drive measurable results and deliver key initiatives within demanding timelines and evolving priorities.
  • Proven adaptability in dynamic, fast-paced environments with frequently changing priorities and time-sensitive requests.
  • Flexibility for odd hours and on-call duties is required to support critical operations.
  • Extensive experience as an IT Systems Engineer in a high-growth, fast-paced corporate environment.
  • Any Okta certifications (e.g., Okta Certified Professional, Administrator, Consultant) are highly preferred.
  • Bachelor’s degree in Information Technology, Computer Science, or a related technical field is a plus.
