Senior Red Team Operator

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.

Every operator knows the ending. You found the path, chained it to access the crown jewel, and wrote it up. Then the engagement closed, the environment changed the next week, and nobody walked that kill chain again until next year's test. Armadin is built to end that cycle.

We're building an agentic attacker swarm. These are specialized AI agents running custom models that discover, exploit, and chain vulnerabilities across external, internal, identity, cloud, and application attack surfaces. They run continuously, at machine speed, against live production environments. Until recently, nobody could put a nation-state-caliber adversary inside every network around the clock. That's the hyperattack, and it's what we do.

In one recent engagement, the swarm generated more than 17 million offensive actions in three days and validated 38 attack paths. That's the scale your tradecraft will run at.

As a Senior Red Team Operator, your tradecraft is the training signal. You'll run hands-on operations, and then you'll encode how you think into the reasoning our agents use at scale: how you pick a foothold, abuse an application's logic, pivot through identity, separate what's actually exploitable from scanner noise, and map the blast radius once you're in. You'll pressure-test full kill chains end to end, find where the swarm is naive, and teach it to move like an expert, using AI throughout your own workflow to go faster and deeper.

The problems here are new ones:

• What does a kill chain look like when it can branch a thousand ways in parallel?
• How do you prove exploitability instead of just flagging it?
• What does a continuous hyperattack find that a two-week engagement never could?

You'll work alongside operators who have spent decades on the front lines of red teaming and the AI engineers turning that experience into autonomous offense. It's a small, scrappy group with high ownership, and the work you ship reaches enterprises through industry leading partners. If you've ever finished an op thinking "imagine running this everywhere, all the time," this is where you get to do it.

• Run full kill chains, not checklists. Attack web, mobile, API, and thick/thin client applications the way a real adversary would, hunting logic flaws and chaining weaknesses into paths scanners never see.
• Prove what's exploitable. Turn candidate findings into working exploitation with clear evidence, and separate real risk from noise.
• Map the blast radius. Follow every foothold to its end, from application compromise to identity, cloud, and data, and show what an attacker could actually reach.
• Read code like an attacker. Review source across languages and frameworks for control-flow flaws, injection paths, and insecure design, using AI-assisted analysis to cover more ground faster.
• Take applications apart. Use static and dynamic analysis, binary reversing, runtime…
