Employer immigration record

from this employer's Department of Labor filings

Files H-1B transfers

7 transfer filings in the last year, covering 7 workers. Median labor-condition decision: 7 days. An employer that already files transfers is one that can take over an existing H-1B.

Sourced from Department of Labor LCA, PERM and prevailing-wage disclosure data. Employer matching is by name, so figures may be split across an employer's legal entities. Absence of a filing means none appears in our copy of the data, not that none exists.

About the role

  • Brain Co.'s products are built on agentic infrastructure - AI that takes actions, calls tools, and operates inside complex institutional workflows.
  • Integrate security into the development lifecycle - code review, CI/CD pipelines, and pre-deployment checks - catching risk before it reaches production.
  • Conduct threat modeling across product features and release cycles, translating risk into concrete controls that ship alongside each product.

Responsibilities

  • Brain Co. builds AI-native operating systems for large, regulated institutions.
  • Every project here ships to production and is expected to create measurable customer value and impact.
  • You will write code, ship security tooling, and work directly with product and ML engineers to build security in from the start rather than bolt it on after.
  • Build and maintain security tooling and automated checks that scale your reach across the codebase - using AI to move faster and cover more ground than manual review alone could.
  • Define what application and AI security looks like at a company building frontier AI for governments, hospitals, and critical industries - from the ground up.
  • Build the security function AI-natively - using the same technology you're helping secure to scale your own work and impact.
  • Thrive in high-agency environments and want to own and grow the application security function as the company scales.

Requirements

  • The degree varies by product, but the underlying security surface is consistent: how agents are authorized, what they can touch, and how that is controlled at the application layer.
  • Have 5+ years of experience in application security or product security, with hands-on experience on production systems at scale.
  • Experience with agent security, LLM application security, or building authorization and guardrail systems for agentic pipelines.
  • Proficiency in Python, Go, or TypeScript for security tooling and automation.
  • Experience with SAST/DAST tooling or integrating automated security checks into developer workflows at scale.

Compensation

  • Earn competitive compensation and meaningful equity in a high-growth company.

  • ABOUT BRAIN CO.

  • Joining now means shaping both the company and a new category of applied AI.
  • 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.
