About the role

About Us

Armadin's standard text

At Armadin, we're a group of engineers, researchers, and security researchers on a mission to redefine what proactive security can do in the AI era. Cyberattacks are becoming autonomous and relentless and we believe defending against threats before they materialize is one of the most powerful ways to protect the institutions the world depends on.

We're building autonomous proactive security from the ground up, reinforcing the tradecraft of elite security practioners into purpose-built security models and agents that discover risk and remediate it before organizations are breached.

Led by Kevin Mandia, founder of Mandiant ($5.4B exit to Google), our team brings together researchers and engineers from Google, xAI, Meta, Stanford, Georgia Tech, Waterloo, Berkeley, and MIT to reinvent security for an adversary that never sleeps.

What You'll Do

  • Own Core Portal Experiences: Turn complex artifacts and graph data into views customers can navigate clearly, with strong visual design.
  • Partner with Product & Design: Make dense security data intuitive, trustworthy, and increasingly AI-powered.
  • Build for Scale: Ship frontend and full-stack systems that scale gracefully with data, customers, and surface area.
  • Raise the Bar: Mentor engineers through technical guidance, code review, and design partnership.

What You'll Bring

  • Frontend Depth: Expertise in a modern frontend framework, with a strong full-stack foundation. You’ve shipped polished, customer-facing product experiences and bring sound engineering judgment across the frontend and backend.
  • End-to-End Execution: You turn ambiguous problems into shipped, reliable software.
  • Product Partnership: You simplify genuinely complex domains alongside Product and Design while staying hands-on in the code.
  • AI Fluency: AI is native to how you work.

Even Better With

  • Products that present complex, high-stakes data to expert users (data visualization, graph rendering, D3 or similar).
  • Enterprise products built for reliability, scale, and trust.
  • Scaling frontend and design systems across a growing surface and team.
