Harvey Software Engineer, Agents at Harvey builds AI agent systems for legal professionals, focusing on model selection, context management, and tool creation. The role involves partnering with customers and PMs to design evaluations and optimize agent performance.

Responsibilities

As a Software Engineer, Agents, you'll build the systems that make our AI agents indispensable to legal professionals.
We're looking for engineers and researchers who are immersed in the space, driven to ship impactful products, and are experienced in using practical evaluations to drive task completion quality and customer delight.
Representative Projects
Save weeks of effort on high pressure M&A deals by automating information requests and diligence checks across hundreds of thousands of files with retrieval and file editing agents.
Dramatically speed up deal turnaround speed by improving the latency and quality of agents on applying a standard legal "playbook" to contracts.
Ensure that our clients win their complex, data-hungry litigation cases by optimizing our multi-source retrieval agents.
Enable board-ready PowerPoint generation by tuning the harness and libraries for coding agents.
Partner with customers and PMs to understand legal workflows, design practical evaluations that capture what “excellent” means, and ship agents that get the job done.
Optimize agent performance through prompt engineering, model selection, tool design, skill writing, context window management, and eval harness development.
Work with our model infra team to design and implement infrastructure for low-latency agent execution, including caching strategies, parallel tool calls, or subagent patterns.
Improve our observability and instrumentation to profile agent behavior, identify bottlenecks, and drive optimization decisions.
Stay current on new developments in agentic systems and bring those learnings back to the products we build.
