About The Position

Langfuse is an open-source LLM Engineering Platform that helps teams build useful AI applications through tracing, evaluation, and prompt management. Now part of ClickHouse, Langfuse aims to be the 'Datadog' for LLM observability. The platform is trusted by numerous large companies and has a significant open-source presence. The company is seeking a Product Marketing Lead to define and execute the market strategy for Langfuse. This is a senior individual contributor role with a focus on product marketing strategy and execution across positioning, launches, website narrative, funnel optimization, customer proof, onboarding, sales collateral, and communicating the value of Langfuse to technical users. While people management is a possibility for the future, the immediate focus is on strategic judgment and excellent execution. The ideal candidate has prior experience marketing technical products to developers, understanding the importance of specificity, usefulness, technical honesty, and product trialability. The role involves building category narratives as well as refining specific marketing assets like onboarding emails, pricing pages, launch posts, sales decks, and conversion reports. This is an opportunity to join a rapidly growing open-source AI infrastructure company in a category that is still being defined.

Requirements

Meaningful experience in product marketing, developer marketing, DevRel, growth, or GTM for a technical product
Marketed to developers, infrastructure teams, AI teams, data teams, security teams, or another highly technical audience
Exceptionally strong writing skills; ability to make complex technical ideas clear without making them shallow
Strong product intuition and ability to use the product sufficiently to be credible with engineers, founders, and technical buyers

Experience leading launches, positioning, website messaging, sales enablement, customer proof, and product narratives end-to-end
Ability to lead through clarity, planning, and execution, whether or not directly managing people
High quality bar for developer-facing marketing and a low tolerance for vague language, buzzwords, or content that does not help the user
Comfort operating in ambiguity and turning messy input into a clear plan
Excitement about AI engineering and staying close to what developers are actually building

Nice To Haves

Already create content: blog posts, talks, product explainers, social posts, newsletters, videos, docs, or open-source examples
Original opinions that experienced technical people value
Comfortable on camera and on stage

Make the Langfuse website sharper: clearer homepage narrative, product pages, customer proof, conversion paths, SEO/GEO inputs, and developer-facing explanations that are precise and useful
Build a repeatable launch system across product updates, changelog, blog, social, email, docs, website surfaces, sales enablement, and ClickHouse GTM channels
Lead customer marketing: customer stories, use cases, proof points, quotes, logo strategy, launch references, and reusable sales narratives

Conduct market and competitive analysis across LLM observability, evals, agent observability, prompt management, and related developer tooling
Work with ClickHouse marketing, sales, solutions, and field teams so Langfuse benefits from the larger GTM engine without losing its developer voice
