AI Harness Engineer

About the role

We're building the next generation of secure AI infrastructure. Our team is creating the foundational technologies that allow AI agents to operate safely, securely, and reliably at scale. This includes building secure agent control planes, embedded controls, developer tooling, observability, and infrastructure that enables production-ready AI systems. This is a hands-on engineering role for someone who enjoys building products from the ground up. You'll partner closely with AI researchers and backend engineers to rapidly move ideas into production while helping establish engineering best practices across our AI Center of Excellence.

Responsibilities

• Design and build secure AI infrastructure for production AI agents.
• Develop Agent Control Plane capabilities that manage, monitor, and secure agent execution.
• Build embedded controls and security mechanisms directly into AI agents.
• Develop reusable services, APIs, and developer tooling that support AI applications.
• Build and maintain integrations with modern Agent SDKs and Model Context Protocol (MCP).
• Design backend microservices using Python and AWS.
• Build observability into AI systems, including telemetry, monitoring, tracing, and operational visibility.
• Develop public-facing developer tools and command-line interfaces (CLI).
• Partner closely with AI researchers to rapidly transition prototypes into production-ready systems.
• Owning projects from architecture through deployment.
• Help define engineering standards and reusable patterns across the AI platform.
• Collaborate with stakeholders across the board in our Product, Sales, and Executive teams.
• Collaborate with senior engineers while independently leading technical initiatives when appropriate.
