Employer immigration record

from this employer's Department of Labor filings

Files H-1B transfers

6 transfer filings in the last year, covering 6 workers. Median labor-condition decision: 8 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

  • An AI-native cybersecurity platform is only as trustworthy as the systems it runs on.
  • Get the foundation wrong and every AI agent built on top inherits that risk.
  • As a Principal Software Engineer, you'll help define the technical foundation of our AI-native cybersecurity platform.

Responsibilities

  • Lead design of scalable backend systems for our AI-native cybersecurity platform.
  • Drive complex technical initiatives from 0→1, including system design, technical strategy, implementation, and operationalization.
  • Partner with product, AI, security, and platform teams to turn ambiguous business and customer problems into solid technical solutions.
  • Lead design discussions and provide technical leadership across multiple engineering domains and initiatives.
  • Mentor engineers through technical guidance, design reviews, and hands-on collaboration.
  • 15+ years of professional software engineering experience building and operating production-grade distributed systems.
  • Proven experience leading the design and delivery of large-scale, highly available cloud-native systems.
  • Strong system design expertise, including distributed systems, APIs, event-driven architectures, data-intensive applications, and infrastructure scalability.
  • You'll lead system design, drive complex technical initiatives from concept to production, and mentor engineers across the organization.

Requirements

  • Experience leading complex technical projects with significant ambiguity and cross-functional coordination.
  • Strong proficiency in one or more backend languages such as Rust, Python, TypeScript, or Go.
  • Strong communication skills, with the ability to explain complex technical concepts to both technical and non-technical audiences.

Nice to have

  • Background in cybersecurity, security operations, or high-sensitivity infrastructure environments.
  • Experience designing multi-tenant SaaS platforms at scale.
  • Familiarity with real-time data pipelines, streaming systems, and large-scale telemetry processing.
  • Experience working in high-growth startup environments.
  • 7AI is the foundational AI security company.
  • Our platform pairs a federated SIEM with AI agents that detect, investigate, respond, and hunt, plus dedicated threat hunting and threat intelligence, with humans on the loop.
  • That's the appeal:
  • you'll join at a pivotal stage where your work shapes what 7AI becomes, alongside security veterans who've built this before.

Company info

  • Founded in 2024 by Cybereason co-founders Lior Div and Yonatan Striem-Amit, we came out of stealth in February 2025 to take on the non-human work of the SOC.
  • Our culture runs on respect, collaboration, and a shared bar for excellence, all pointed at one goal, delivering real outcomes for the customers who trust us to defend them.
