About this role

ListenLabs is hiring a Member of Technical Staff for Application Security in San Francisco, CA to build security directly into a complex AI-native product. This role suits an engineer who prefers writing production code and shipping fixes over external auditing.

Role Overview

ListenLabs seeks an engineer to integrate security into an AI-native product platform that conducts AI-moderated video interviews at scale. The company handles profiles for millions of users and builds toward an ecosystem where AI agents and enterprise customers interact via the Human API. The position focuses on proactive security engineering rather than traditional auditing or writing tickets.

Key Responsibilities

Design protections for sensitive user data, including encryption, access boundaries, retention policies, and abuse resistance.
Ensure multi-tenant isolation holds up across platform staff, customer admins, and study participants.
Threat-model the AI-native attack surface, covering prompt injection, data exfiltration, and tool permissions for LLMs.
Establish authentication, authorization, and API surfaces for programmatic and agentic callers of the Human API.
Build security engineering platforms, including secure-by-default libraries, CI pipeline scans, and supply chain hygiene.
Review architecture and pull requests alongside product engineers and write code fixes directly.

Requirements

Possess junior-level or better development skills with comfort in a modern backend stack such as TypeScript and Terraform.
Understand application security fundamentals including authentication, authorization, secrets management, and secure API design.
Think in terms of trust boundaries, threat models, and blast radius rather than relying purely on checklists.
Focus on closing loops by shipping guardrails, libraries, pipeline checks, or code patches.
Communicate complex ideas effectively in writing within a remote-friendly, independent work environment.
