Senior Security Engineer – Hyper-Growth AI Unicorn – San Fran | Up to $300k + Equity

I'm working with a fast-scaling AI unicorn in NYC that's embedding AI deeply into enterprise workflows - and they need a Senior Security Engineer to help own and build out the security function.

• $3BN+ valuation with serious momentum behind it
• Significant VC backing from recognised tier-1 investors
• Engineering team drawn from FAANGfrontier AI labstop trading firms, and elite startups

This is a hands-on security engineering role at a firm moving at serious pace - build the function, set the standard, own the impact.

What you'll be working on:

• Owning and evolving the firm's security posture - AppSec, CloudSec, and beyond
• Automating security processes end-to-end - vulnerability management, asset management, patch management
• Embedding security-first principles across the product and engineering org
• Leading cloud security across all infrastructure
• Partnering with engineering and leadership to align security with business goals

What they're looking for:

• Proven hands-on security engineering experience at a high-growth startup, FAANG, trading firm, or frontier AI lab
• Strong cloud security expertise - you've owned it at scale
• Solid engineering fundamentals - Python, Go, or similar
• Track record automating security processes and integrating cloud-native tooling
• A builder - someone who writes the playbook rather than following one

What's on offer:

• Up to $300,000 base + meaningful equity
• Work alongside engineers from FAANG, top trading firms, and frontier AI labs
• Ground-floor security scope - your work shapes the entire function
• In-office, NYC - high-velocity culture built for people who get things done

If your background is in FAANG, a top trading firm, elite start-up, or a frontier AI lab - this is exactly the kind of role worth a conversation.
