Security Engineer, Detection & Response

About Thinking Machines The mission of Thinking Machines is to build AI that extends human will and judgment. We are training frontier models with Inkling, developing Tinker to let people make models their own, and crafting interfaces that broaden human-AI communication. We believe the future worth building is human, and we're hiring people who want to build it.

About the Role We’re looking for a detection and response engineer to build how we find, investigate, and stop threats against our company, platforms, models, and data. You’ll own the pipelines that turn raw telemetry into high-fidelity detections, lead the response when real incidents happen, and run a threat intelligence practice that keeps our defenses focused on the adversaries who actually target frontier AI labs. You’ll partner closely with security, infrastructure, research, and product teams so that detection and response scale with the company instead of slowing it down.

What You’ll Do Lead incident response end-to-end: triage, scoping, containment, eradication, recovery, and blameless postmortems that turn lessons into new detections and controls. Design, build, and operate the security data pipelines and tooling that power detection and response: collecting, normalizing, enriching, and storing telemetry from cloud, Kubernetes, identity, endpoint, SaaS, and application sources. Author, deploy, and maintain high-fidelity detections across SIEM, endpoint, cloud, and security tooling Build and run our threat in
