Job description

Role overview

Set the technical direction for a shared cybersecurity platform that hosts AI agents, coordinates their work, and distributes intelligence across a suite of security products. The platform also provides common services such as authentication, shared datasets, and configuration. As a principal individual contributor, you’ll define architecture and engineering standards across the platform and contribute to principles used by a broader engineering organization; this is described as a technical craft role rather than a people-management position.

• Own architecture spanning agent execution and orchestration, integrations, data and context layers, APIs, permissions, and shared services.
• Design for both hosted and customer-managed deployments, including tenant isolation, upgrades, configuration, and operating in customer environments.
• Make and guide decisions on platform qualities such as scalability, resilience, security, and maintainability.
• Contribute engineering principles and standards that can be shared across product teams.

Requirements

• The available description establishes principal-level ownership of platform architecture and technical direction, but does not include the detailed qualifications or experience requirements.

Benefits and work setup

• Remote-first flexibility.
• Competitive compensation and equity are listed, with no amounts specified.
• A baseline of 25 days of paid time off, plus paid volunteer days.
• Equipment and additional support for remote work and professional development.
• Two annual in-person gatherings: one company-wide and one team event.
