Security Engineer

Hark is an artificial intelligence company building advanced, personalized intelligence.

One that is proactive, multimodal, and capable of interacting with the world through speech, text, vision, and persistent memory.

We're pairing that intelligence with next-generation hardware to create a universal interface between humans and machines.

While today's AI largely operates through chat boxes and decade-old devices, Hark is focused on what comes next: agentic systems that interact naturally with people and the real world.

To get there, we're developing multimodal models and next-generation AI hardware together - designed from the ground up as a single, unified interface for a new era of intelligent systems.

We're hiring a Member of Technical Staff (Security Engineer) to own security engineering at Hark.

You'll threat-model our systems, harden our cloud and product infrastructure, build detection capabilities, and lead incident response when things go wrong.

As AI agents become a core part of our product, you'll also be on the frontier of LLM and agent security — a space with very few established playbooks.

This role is hands-on; you'll be building and operating, not managing or auditing.
