10+ years of experience in IT Operations / Client Platform / Endpoint Engineering in modern, high-growth environments.

We are looking for a hands‑on, generalist IT / Client Platform Engineer to own day‑to‑day IT operations while building scalable foundations across identity, access, device management, and onboarding/offboarding.

This is not just a help desk role. While you will support employees directly, your primary mission is to design and implement automated, secure, and scalable IT systems, especially around identity (SSO/SCIM), Mac fleet management, and AWS access.

You’ll be the backbone of our internal IT platform, ensuring employees have seamless access to what they need, securely and efficiently.

• Own Google Workspace administration (email, groups, security settings, user lifecycle).
• Manage and improve SSO integrations across SaaS apps (primarily SAML-based).
• Troubleshoot authentication issues (SSO, MFA, sessions, login failures).
• Implement and improve SCIM provisioning (automated create/update/deprovision flows).
• Drive clean and automated joiner / mover / leaver processes.
• Maintain a structured SaaS inventory (owners, licenses, criticality, usage).
• Run periodic access reviews and enforce least‑privilege access by default.

• Own Mac fleet management end-to-end (primarily macOS).
• Manage MDM solutions (Rippling MDM; Kandji experience highly relevant).
• Implement and maintain zero-touch deployment via Apple Business Manager / Automated Device Enrollment.
• Standardize device configuration (File Vault, OS updates, security baselines, Wi‑Fi/VPN profiles).
• Manage software packaging and deployment (Munki and/or Auto Pkg are a plus).
• Maintain asset inventory, lifecycle tracking, compliance, and secure offboarding wipes.

• Manage AWS IAM access (federated access, users, roles, policies).
• Support AWS account administration and permissions troubleshooting.
• Enforce secure access practices: MFA, key rotation, role-based access, minimizing long-lived credentials.
• Support audits and access reviews related to AWS environments.

• Provide L1/L2 support for employees (accounts, laptops, SaaS issues).
• Own internal ticket flow (prioritization, response times, documentation).
• Create and maintain clear runbooks,…
