Remote Full-time Now Hiring

Note: The job is a remote job and is open to candidates in USA. Fluidstack is focused on building civilization-scale infrastructure for AI, and they are seeking a Security Engineer to secure their corporate IT environment. The role involves building a security program from scratch and managing the security of critical assets in a fast-growing company.

Responsibilities

  • Secure the corporate environment end to end: identity, endpoints, SaaS, and email for a workforce growing 10x
  • Build detection and response for the corp attack surface, from phishing to token theft to insider risk
  • Engineer zero-trust access: SSO, device trust, and least-privilege provisioning that scale with hiring instead of against it
  • Automate the controls so security runs as code and policy, not tickets and exceptions

Skills

  • You've secured a fast-growing company's corp stack hands-on: IdP, MDM, email, SaaS
  • You've built detections that caught real attacks, and tuned out the noise that buries teams
  • You treat identity as the perimeter and have implemented that in practice
  • You automate anything you do twice, in code, not runbooks
  • You've responded to live incidents and made the containment call under pressure
  • Bonus: Okta or equivalent at depth
  • SIEM and SOAR engineering
  • MacOS and Windows fleet security
  • Insider-risk programs
