Software Engineer - Applied AI

Responsibilities

• Improve accuracy on our core extractions. Documents can be long, amended in unanticipated ways, or have unclear language. You'll work with our JDs and other experts to find the failure modes, figure out what's happening, fix them
• Own our evals. The only way to maintain a system like this is through tests and evals. We have a strong foundation for evals, but think that it can be better and want to invest heavily here. You'll design and maintain the suites that tell us whether a change helped and to prevent regressions
• Improve our shared agent harness. Tooling, parallel tool calls, context strategy, and the orchestration behind our agentic advisory workflows
• Design for human review. Our users don't want a black box. Work with product and design on how a suggestion gets surfaced, explained, and accepted or rejected, then feed the corrections back into the system
• Be informed on the state of AI. Models, capabilities, and usage pattern best practices shift weekly and it's our job to be aware of what's out there so we can remain at the frontier of the industry. You'll stay on top of the latest developments and, leveraging our evals, take advantage of the rising tide of models!
