<h5>Persons in these roles are expected to work from our offices in Seattle. On-site requirements vary based on position and team.

You'll own end-to-end product surfaces: designing interactions for long-running, non-deterministic agents, contributing to the agent architecture behind them, building React applications on top of our agent infrastructure, and shaping how users understand and steer what the system is doing. You'll work closely with UX designers, AI/ML engineers, and research scientists. You're a seasoned engineer who thrives in greenfield environments and has a track record of building intuitive, high-performance user experiences. You're energized by the design problems that come with agentic products: streaming state, ambiguous outputs, and users who need to trust the work.</p> <p><strong>Who We Are:&nbsp;</strong></p> <p>The Agentic Applications team builds<a href="https://asta.allen.ai"> Asta</a>, Ai2's open research assistant for science, which finds, summarizes, and analyzes scientific evidence across millions of papers. Go try it; it's public. Our hardest problems are interface problems: a scientist won't trust an answer they can't verify, so our agents have to show their work — and real research doesn't finish in a chat session, so they have to run long, hold state, and stay legible across the whole stretch. We build in a tight loop with Ai2's research org and the researchers who use what we ship.</p> <p><strong>Your Next Challenge:</strong></p> <p>The essential functions include, but are not limited to the following:</p> <ul> <li>Work closely with UX designers, product managers, and research scientists to develop rich UI experiences using React and robust backend services in Python.</li> <li>Contribute to the agent architecture behind these products, shaping how agents, tools, and services fit together.</li> <li>Engage in the entire software development lifecycle, from ideation and design through implementation and testing to deployment and operational support, with a strong sense of ownership for results.</li> <li>Communicate effectively across engineering, product, and research teams to align priorities and drive projects to completion.</li> <li>M
