Member of Technical Staff (AI Software Engineer, Agent Engine)

Description

The company is building agentic products, including its Computer product, the Comet ecosystem and an Agent API, for a large base of users.

The Agent Engine team works on agent experiences and frontier intelligence systems, combining engineering with applied research.

Open problems the team tackles include agent harnesses for high-stakes work, action and decision models, consistent behavior across local, headless cloud and custom execution environments, secure agent capabilities, and data representations for agent-environment interaction.

Responsibilities

• Design agent harnesses and systems that carry out high-stakes, mission-critical work for users.
• Build action and decision models that work out how to reach user goals from complex multimodal states.
• Deliver a consistent experience across local execution, headless cloud, custom executors and other environments using sound system design and flexible abstractions.
• Develop permission architectures, payload classifiers and other methods for secure-by-design agent capabilities.
• Design data representations and interaction modes between agents and their environments.

Requirements

• Solid working knowledge of the AI systems stack.
• Proficiency in Python.
• Significant experience in at least one of: harness engineering, agent skills and plugin architectures, model training and reinforcement learning, or browser technologies such as CDP, Playwright and extension development.
• Strong technical instincts and a good sense of user experience quality.
• Comfortable on a small, fast-moving team and inclined to take ownership.
• Experience with TypeScript, Go or Rust is a plus.
• Enjoys shipping products that people find useful and delightful.
