Our Mission
Rebuild how the world works, to make institutions work better for the people they serve.
About Brain Co.
Brain Co. builds AI-native operating systems for large, regulated institutions. Each system is built for a specific industry, powered by agents that push real workflows forward. Underneath it all is Atlas, our proprietary platform that keeps customers in control, secure by design, and never locked into one model.
Why Now
Brain Co. is entering its next phase of production deployments on a national scale with an elite team built from Palantir, Google, Meta, and Nvidia, and a growing footprint across government, insurance, health, and financial services.
Joining now means shaping both the company and a new category of applied AI. Every project here ships to production and is expected to create measurable customer value and impact.
You'll work alongside exceptional peers on some of the hardest problems in applied AI. It’s the kind of work you'll still be proud of in ten years from now.
We are looking for a Security Engineer, Detection & Response to build and operate our detection and response capabilities as Brain Co. expands. Reporting directly to the Head of Security, you will partner closely with engineering, infrastructure, infrastructure security, IT, and operational teams to protect our environments and respond effectively to security incidents.
This is an engineering-focused builder role rather than a passive alert-monitoring position. You will strengthen our security posture from the ground up: designing high-signal detections, automating triage and investigation workflows, leading cross-functional incident response, and converting incident findings into safer engineering defaults across the company.
The program is early enough that your judgment will shape the tooling, workflows, metrics, and operating model—not just the alerts you investigate. You will have significant autonomy to improve signal quality, streamline integrations, and turn incident lessons into stronger engineering defaults across the organization.
Design, build, and maintain automation, playbooks, and systems for timely triage, investigation, and incident response, using sound software engineering practices and modern AI tools where they add value.
Develop and refine high-signal detections so security findings are actionable and noise is minimized.
Integrate security telemetry and tooling across our cloud and application stack to enable consistent investigation and self-service triage.
Lead cross-functional incident response across applications, cloud infrastructure, endpoints, identity, and internal services.
Translate incident data and response metrics into secure-by-design improvements alongside product and infrastructure teams.
Continuously evaluate response procedures and partner across engineering, infrastructure security, IT, and operational teams to close gaps and improve the operating model.
