Senior Engineer II, Chromium

Role overview Build and strengthen browser-based security capabilities that protect users and AI agents from web threats and unsafe activity. The work spans deep C++ browser engineering, networking and security controls, AI agent integrations, and cloud services that support detection and enforcement at scale.

Responsibilities - Develop and maintain Chromium-based components in C++ across browser, rendering, networking, and related layers. - Design browser and agent workflow controls to detect prompt injection and manage unapproved AI use. - Apply HTTP and web security knowledge to harden browser isolation, proxy or gateway interception, and network-facing services. - Work with AI engineering partners to integrate agent capabilities and Model Context Protocol servers. - Build supporting tools, prototypes, and detection services using Python or Rust. - Deploy and operate cloud infrastructure and orchestration for agent and threat-detection workloads. - Investigate and improve performance across browser and backend systems, collaborating with product, security, and AI teams to ship complete features.

Requirements - At least five years of software engineering experience, with strong C++ systems programming skills. - Solid networking fundamentals, including HTTP security, web protocols, or client-side security architecture. - Bachelor’s degree or higher in computer science or a related field, or equivalent practical experience.

Nice to have - Chromium internals experience or comparable work on large, high-performance C++ systems. - Interest or experience in AI security, prompt injection defense, shadow AI detection, data loss prevention, or agent workflows. - Python or Rust experience, and familiarity with AI agents, Chrome DevTools Protocol, or MCP servers. - Experience with AWS or GCP, Kubernetes, Terraform, and Linux.
