From the company's job description

Menlo Security is the leader in Browser Security for human and agentic workforces. Our mission is to enable humans and agents to connect, communicate, and collaborate securely, without compromise. The Menlo Browser Security Platform protects organizations from cyberattacks by stopping threats across the web, documents, and email before they reach the user. With Menlo Agent Runtime Security (MARS), that protection now extends to the AI agents working alongside every employee. Menlo Security is trusted by major global businesses, including Fortune 500 companies and government agencies, to protect their most valuable asset, their data, and is backed by top-tier investors.

About the Role

Summary

Menlo Security is building MARS for Agents (Menlo Agent Runtime Security), our product line for securing autonomous and hybrid AI agents. This is a category still being defined — standards, architecture patterns, and competitive positioning are all forming in real time, with competitors ranging from established network security vendors to a wave of new agent-security startups.

We are hiring an experienced Product Manager / Product Owner to take end-to-end ownership of a significant, technically complex area within MARS for Agents. The specific scope will be defined in partnership with the hiring manager based on team needs and the background of the person in this role, and will span identity and security concepts, relevant technical protocols, and platform integration and partnership work. The role operates with a high degree of autonomy day to day, working from strategic direction set by the Head of Product, in an environment that runs agile development at high velocity while actively building the process and rigor needed to scale a growing product line.

This is also a team that works the way it builds: AI assistants and LLM-based tools are part of the daily toolkit here — used to synthesize customer and competitive signal, pressure-test requirements, and prototype against MCP clients and agent runtimes before a single line of production code is written. The person in this role will be defining security for a category they are already a fluent, curious user of.
