Senior Security Engineer

Description:

Senior Security Engineer – New York

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 FAANG, frontier AI labs, top 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
