Product Manager, LangSmith

Product Manager

We're looking for a product manager to own key parts of LangSmith. Building AI products is changing the way software teams work; LangSmith is the observability, evals and deployment platform that makes shipping reliable AI systems possible.

This role sits at the intersection of user experience and production infrastructure. You'll partner with engineers to build features that feel intuitive while solving deeply technical problems: versioning complex prompt chains, debugging multi-step agent failures, or designing evaluation systems that scale from 10 to 10,000 test cases.

You'll work directly with customers — from early-stage startups shipping their first agent to enterprises running mission-critical AI systems — to understand where the platform breaks down and what capabilities unlock new workflows.

Responsibilities include:

• Owning the roadmap for a core area of the LangSmith platform.
• Working with customers to understand their challenges and define new product features.
• Working with engineering to define scope, make technical tradeoffs, and ship high-impact features quickly.
• Helping shape product strategy alongside our founders and leadership team.

Qualifications include:

• 3+ years of product management or engineering experience, ideally building developer tools, infrastructure products, or technical SaaS platforms.
• Deeply technical — you can hold your own in conversations about API design, system architecture, data pipelines, and debugging production issues.
• Bias toward action — you'd rather ship, learn, and iterate than build the perfect solution upfront.
• Strong written and verbal communicator who can align cross-functional teams around a shared vision.

Nice to have:

• Computer Science, Engineering, or equivalent technical background.
• Previous experience at a high-growth startup or developer-focused company.
• Hands-on experience building with LLMs, agents, or AI applications.

Annual salary range: $180,000-$215,000
