Application Security Lead

Hightouch is the modern AI platform for marketing and growth teams. Our AI agents reimagine marketing workflows, allowing marketers to create content, plan campaigns, and execute strategies with transformational velocity. Built on advances in LLMs, agentic AI, and cloud data warehouses like Snowflake and Databricks, we partner with leaders like Domino’s, Chime, and Spotify.

This is our first dedicated security hire, a rare chance to define the function from the ground up. You'll own Hightouch's application security posture end-to-end as we scale from 70 to 140+ engineers. It's a hands-on, high-autonomy role focused on the codebase, not meetings.

Solve hard problems at the intersection of security and distributed systems, including multi-tenant isolation on a system running ~1M data syncs per day and ingesting 100K+ events/sec. Handle sub-tenant access control, security architecture for compute isolation, threat modeling, and hardening of internet-facing APIs. Support multi-region and multi-cloud backends to meet global data residency needs.

Our team approaches challenges with first-principles thinking, moves quickly and efficiently, and treats each other with compassion and kindness. We seek strong communicators with a growth mindset, motivated and persistent in achieving goals. You'll own your roadmap, identifying and fixing the highest-leverage security problems.
