At Hark, we are building the most advanced personal intelligence in the world.
About the role
We're hiring a Member of Technical Staff (Application Security Engineer) to own the security of the software Hark ships. You'll review design and code, find and fix vulnerabilities in our backend services, mobile apps, and third-party integrations, and build the guardrails that let engineers move fast without shipping bugs. Our agents act on behalf of users across their apps and data, so you'll also be defining how to secure LLM and agent systems, a space with very few established playbooks. Found on 1752vc Careers, the job board for startup and VC roles.
What they're looking for
- 4–8 years of hands-on application or product security engineering experience
- Strong software engineering skills, you can read, write, and ship production code (Go strongly preferred, Python, TypeScript, Swift, or Kotlin also valuable)
- Deep understanding of web and API vulnerability classes (OWASP Top 10, SSRF, IDOR/BOLA, authz flaws, injection) and how to fix them at the root
- Hands-on experience with OAuth 2.0 / OIDC, session management, and securing multi-tenant systems
- Experience running secure code review and threat modeling in a fast-moving engineering org
- Experience turning scanner and runtime findings into fixes using tools like Wiz Code, Wiz Cloud, and Datadog SIEM (or equivalent SAST/SCA, CNAPP, and SIEM tools)
More about this role
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.
