## About the role

As a Senior IT Systems Engineer on the IT Systems team, you own the design, implementation, and long-term health of the enterprise systems Klaviyo runs on identity, endpoint management, and the SaaS platforms every Klaviyo touches. You will lead projects end to end, from SSO/SCIM rollouts to complex multi-tool integrations and automations, and you will be trusted to take an ambiguous business problem, define the problem statement yourself, and deliver a solution that scales.

## What they're looking for

- 4+ years of hands-on experience as a systems engineer or systems administrator, with a track record of owning enterprise systems in production not just operating them, but deciding how they should work
- You define problem statements yourself. You can take a vague or contested business need, scope it, drive alignment with stakeholders, and deliver with minimal direction without losing the thread when priorities shift
- Deep working knowledge across a wide range of IT systems, including enterprise device management, identity and access management, and endpoint security
- You have deployed and managed macOS and iOS devices at scale through an MDM (Jamf preferred), including configuration profiles, policies, and OS update strategy. Windows management (Intune, Autopilot) is a strong plus
- You have administered core SaaS platforms such as Google Workspace, Slack, Atlassian, and Zoom, including their security and admin controls
- Hands-on experience with IdP configuration, management, and maintenance: SSO (SAML/OIDC), SCIM provisioning, group and role design, and app onboarding. Experience with Okta or Entra ID (Azure AD) is preferred
