Senior Staff AI Engineer (US)

We are looking for a Senior Staff AI Engineer with 8-15 years of experience to own the technical direction of our agentic AI harness and transform how chemists and AI reason about science together. You will be the most senior hands-on IC on the Agentic AI team, building the orchestration, tool use, memory, and reasoning layer at the center of Albert OS, the first AI-native operating system for materials science. This is a 0-to-1 role where you'll define how the entire platform shifts from a chat-based interface to an agentic-first experience, working with trillions of proprietary scientific tokens that no one else in the world has access to. You'll lead two junior engineers on the AI harness while partnering closely with product and ML leadership to expand agent capabilities across every surface of the platform.

What will you be doing?

• Build and expand the agentic harness (think Claude Code or Devin, but for chemistry), designing orchestration, tool use, memory, planning, and evaluation layers for production agent systems

• Set the technical direction for shifting the entire Albert OS platform from a chat-style interface to an agentic-first experience where agents operate across every surface

• Develop agentic tools and sub-agent personas that operationalize how chemists think and work in their day-to-day workflows

• Integrate frontier reasoning models into the application, expanding their capabilities and potentially contributing to fine-tuning programs for domain-specific reasoning

• Make agent behavior observable and measurable through tracing and evaluation against real scientific tasks, driving reliability to the level where partners trust agents to act autonomously
