Senior FP&A Analyst, COGS

Armadin•Palo Alto, CA

About The Position

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. As a Senior FP&A Analyst, you'll own financial planning and cost architecture across two critical pillars: Services costs (our go-to-market delivery engine) and AI/compute infrastructure (the heartbeat of our autonomous systems). This isn't a spreadsheet role. You're building cost models from scratch, working across technical and operational teams, and making sure every dollar spent maps to a strategic outcome. You'll partner directly with Expertise and Product leadership teams. You'll own the monthly cost close, build forecasts that inform hiring and feature decisions, and create feedback loops that show product teams what it actually costs to run their systems. You'll operate with radical autonomy and speed.
