Summary from the posting

There is no MSSP and no tier-1 queue here. Detection & Response engineers own their detections end to end: you write them, you tune them, and your team is paged when they fire. The security team is spread across the globe with a follow-the-sun pager rotation so nobody is paged at 3am local.

The adversaries are real. The business is growing fast and the threat surface is growing with it. Defining the necessary telemetry is part of the job.

Detection engineering

  • Build and tune detections across endpoint, identity, SaaS, and cloud, treating them as software: version-controlled, peer-reviewed, and shipped through the same CI/CD practices the rest of engineering uses.

This is a short summary. The full description, requirements and the application form are on Flexport's own career page.
