      <Title>Senior Security Engineer, Enterprise Security</Title>
      <Description><![CDATA[<p>As a Senior Security Engineer, Enterprise Security, you will design and ship the security controls that underpin CoreWeave&#39;s workforce and enterprise stack. You will lead initiatives across identity, access management, device and endpoint security, and SaaS security,partnering closely with IT Engineering, Endpoint, Network, and other security teams.</p>
<p>Your day-to-day will blend hands-on engineering (writing code, building integrations, tuning controls) with architecture and program ownership (setting standards, defining patterns, and driving adoption across teams). You will be responsible for turning high-level objectives,like “implement zero trust for workforce access” or “deploy phishing-resistant MFA at scale”,into concrete designs, automation, and measurable risk reduction.</p>
<p>In this role, you will:</p>
<ul>
<li>Engineer modern identity and access controls</li>
<li>Design, implement, and operate workforce identity solutions (e.g., Okta/Entra and other IdPs) including SSO, MFA, conditional access, and lifecycle automation via SCIM.</li>
<li>Develop and roll out phishing-resistant MFA for high-value accounts and critical access paths (e.g., FIDO2/WebAuthn, hardware keys, device-bound authenticators).</li>
<li>Define and maintain RBAC/IAM patterns for enterprise applications (role models, groups, entitlements, JIT access, and approvals).</li>
</ul>
<ul>
<li>Implement zero trust for workforce and enterprise access</li>
<li>Design and deploy controls that combine user identity, device posture, network context, and application sensitivity to enforce least-privilege access.</li>
<li>Partner with Network and Infrastructure teams to integrate mTLS, service identity, and policy-based access into internal services and admin interfaces.</li>
<li>Help transition from legacy perimeter models to zero trust network access (ZTNA) patterns for employees, contractors, and third parties.</li>
</ul>
<ul>
<li>Secure SaaS and collaboration platforms</li>
<li>Evaluate, onboard, and harden SaaS applications (Google Workspace, Microsoft 365, Slack, HRIS, ticketing, and other business apps) to align with enterprise security policies.</li>
<li>Implement and tune controls such as SCIM provisioning, data access policies, DLP, sharing controls, and audit logging across the SaaS estate.</li>
<li>Partner with business and IT owners to ensure new SaaS applications meet baseline security standards before adoption.</li>
</ul>
<ul>
<li>Harden endpoints and the extended workforce</li>
<li>Collaborate with Endpoint/IT teams to define and enforce baseline configurations for laptops, workstations, and other managed devices via MDM and EDR.</li>
<li>Design secure patterns for contractor and vendor access, including device requirements, identity separation, and time-bound access.</li>
<li>Support investigations and incident response related to identity, endpoint, and SaaS domains.</li>
</ul>
<ul>
<li>Automate and instrument everything you can</li>
<li>Build automation and self-service experiences for access requests, approvals, access reviews, and break-glass workflows.</li>
<li>Develop integrations between IdPs, HRIS, ticketing, and other systems to minimize manual toil and reduce identity-related error rates.</li>
<li>Define and instrument metrics for enterprise security (e.g., MFA coverage, zero trust policy enforcement, joiner/mover/leaver SLA adherence, SaaS posture).</li>
</ul>
<ul>
<li>Partner on detection, response, and governance</li>
<li>Work with Security Operations and SIEM teams to ensure robust visibility into identity, device, and SaaS activity, and to build high-signal detections.</li>
<li>Contribute to policies, standards, and reference architectures that encode enterprise security expectations.</li>
<li>Author clear documentation and runbooks that make it easy for teams to consume and operate the controls you build.</li>
</ul>
