Senior Product Manager

Menlo Security is the leader in Browser Security for human and agentic work forces. 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.

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.

• End-to-end ownership of an assigned surface area of MARS for Agents — across capabilities such as the agent registry, Claude integration, Microsoft Copilot integration, MCP Server, MCP Proxy, and LLM proxy — from researched opportunity, to written requirement, to shipped and supported capability.

• A current, honest, decision-changing competitive point of view for the agent-security category that the wider go-to-market organization can rely on.

• Roadmap delivery: committed roadmap items for the owned surfaces shipped within the target release window.

• Requirements quality: Reduction in mid-sprint requirement clarifications and rework attributable to ambiguous PRDs or acceptance criteria, measured via engineering feedback each quarter.

• Enablement coverage: 100% of shipped capabilities in the owned area have current capability documentation and a delivered briefing to support and solutions engineering at or before release.

• Adoption of shipped capability: Customer adoption or usage of newly released capabilities against a target set at launch, tracked for 90 days post-release.

• Competitive influence: At least one documented roadmap or positioning decision per quarter, traceable to a published competitive finding.

• Own inbound product direction for your area. Research emerging agentic AI capabilities, attacker techniques, and adjacent standards (MCP, A2A, OWASP agentic-security guidance, agent identity frameworks) to determine what MARS for Agents should build next across the agent…
