Langfuse - Product Manager

Langfuse is hiring its first Product Manager. You will work with the founders to define the product vision and set the strategic direction. You will also work with Solution Architects, sales, and marketing. Your input will help shape product decisions.

Engineers at Langfuse own delivery from start to finish. They help find solutions and turn them into technical requirements. They implement and launch the work. They support each launch with documentation and changelogs. They also speak directly with customers to receive feedback on features and educate the roadmap. The whole company helps shape the quarterly roadmap. The engineering team then delivers it.

As Product Manager, you will look beyond the current quarter. You will build a deep understanding of our market and emerging trends. You will also study how engineers use AI to build agentic applications. You will use these insights to create clear product artifacts. They will define the user problems we want to solve and how we want to solve them.

What you will do at Langfuse:

• Shape the product direction and translate long-term opportunities into clear priorities.
• Turn customer, community, and market insights into decisions about what to build and what not to build.
• Lead new product areas from research and scoping through launch.
• Work closely with founders, engineers, designers on APIs, SDKs, infrastructure, UX, and documentation.
• Align founders, engineering, sales, marketing, and key customers without introducing unnecessary processes.
• Make the product-engineering team more effective through clear context, strong judgment, and concise written briefs.
• You will own the quarterly roadmapping process and propose in which direction we should develop Langfuse.

What you will

not do:

Project Management for engineers. Everyone here can organize themselves, you do not need to do this.

Slice large projects into Linear tickets. Single engineers execute on large projects in Langfuse.

Communicate between customers and engineers. Engineers talk to customers daily.

What we are looking for:

• An experienced PM from developer tools, observability, infrastructure, data, or a similarly technical product.
• Technical enough to reason credibly about APIs, SDKs, architecture, and UX tradeoffs.
• You are hands-on: you test products, you talk to users, you maybe build a small prototype.
• Strong strategic thinking, prioritization, and product taste.
• Comfortable with ambiguity, autonomy, and a fast-moving environment.
• Pragmatic, calm, organized, and focused on shipping.
• Excellent written and spoken communication.
• Deeply interested in AI and already using AI tools extensively.
• Experience with open source, enterprise software, or major platform shifts is a plus.
