By combining frontier agentic AI, an enterprise-grade platform, and deep domain expertise, we’re reshaping how critical knowledge work gets done for decades to come.\nThis is a rare chance to help build a generational company at a true inflection point. We have strong product-market fit and world-class investor support. We’re scaling fast and defining a new category in real time. The work is ambitious, the bar is high, and the opportunity for growth - personal, professional, and financial - is unmatched.\nOur team moves fast, takes ownership, and is deeply committed to the mission - operating with intensity, staying close to our customers, and pushing each other for excellence. We live by three values: Decisiveness, Simplicity, and Job's Not Finished. We act quickly on clear judgment over perfect information, we believe simplicity is what scales, and we're never satisfied with where we are. If you want to do the best work of your career alongside people who share that drive, we'd love to build with you.\nAt Harvey, the future of professional services is being written today - and we’re just getting started.\nRole Overview\nAs a Software Engineer, Agents, you'll build the systems that make our AI agents indispensable to legal professionals.\nYou will design environments and actions for agentic professional work, make model selection decisions, manage context windows, create optimal tools, and develop evals that enable faster iteration loops to unlock new capabilities.\nWe'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.\nWhat You'll Do\nPartner with customers and PMs to understand legal workflows, design practical evaluations that capture what “excellent” means, and ship agents that get the job done.\n\nOptimize agent performance through prompt engineering, model selection, tool design, skill writing, context window management, and eval harness development.\n\nWork with our model infra team to design and implement infrastructure for low-latency agent execution, including caching strategies, parallel tool calls, or subagent patterns.\n\nImprove our observability and instrumentation to profile agent behavior, identify bottlenecks, and drive optimization decisions.\n\nStay current on new developments in agentic systems and bring those learnings back to the products we build.\n\nWhat You Have\n10+ years (post-BS/MS) of software engineering experience.\n\nPassion for building effective domain-specific agents.\n\nIterative mindset: you develop proof of concepts, make decisions quickly, and ship v0s.\n\nComfortable with when and how to use evaluations to drive quality.\n\nHumble and adaptable about code and frameworks. We expect you to drive adoption of new best practices as they develop.\n\nWe are hiring for this role across Mid, Senior, and Staff levels.\n\nProficiency in Python and experience working with LLM APIs and agent frameworks.\n\nExperience with shipping user-facing products, either on the backend or full-stack.\n\nCompensation\n$231,000 - $340,000 USD\nDepending on your location, an Applicant Privacy Notice may apply to you.
