About the Role

Define Langfuse's market presence and execute product marketing strategy across positioning, launches, website narrative, funnel, customer proof, onboarding, and sales collateral. This senior individual contributor role requires strategic judgment and excellent execution, with potential for future people management. The role involves marketing technical products to developers, building category narratives, and improving various marketing assets. Join a fast-growing open-source AI infrastructure company to clarify product depth and own the narrative system for Langfuse.

Responsibilities

Own Langfuse product marketing strategy and execution across positioning, messaging, launches, customer proof, website narrative, onboarding, funnel, and sales collateral.
Build the marketing plan for your area: decide what matters, define the sequence, create the operating cadence, and turn strategy into shipped work.
Define and maintain the category story for Langfuse: what we are, what we are not, how we describe LLM observability, evals, prompt management, datasets, agent observability, and the broader LLM engineering workflow.
Own the funnel and conversion plan: website conversion, activation, onboarding, lifecycle emails, self-serve-to-sales handoff, product usage signals, and the metrics marketing reviews every week.
Partner closely with product and engineering to turn product substance into launches, changelogs, blog posts, product pages, demos, webinars, workshops, and technical proof that developers trust.
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.
Create the canonical first-call / webinar narrative for Langfuse and keep sales, solutions, field, and regional motions aligned around it.
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.
Use AI tools and automation to scale the marketing operating system: research, content review, competitive tracking, customer evidence, reporting, and routine workflows.
Lead through clarity, planning, writing, prioritization, and delivery, whether or not you directly manage people.

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.
Exceptional writing skills, making complex technical ideas clear without making them shallow.
Strong product intuition, able to use the product credibly with engineers, founders, and technical buyers.
Understanding of PLG funnels: activation, onboarding, conversion, lifecycle, product usage signals, self-serve growth, and sales-assisted expansion.
Led launches, positioning, website messaging, sales enablement, customer proof, and product narratives end to end.
Ability to lead through clarity, planning, and execution, regardless of direct people management.
High quality bar for developer-facing marketing and a low tolerance for vague language, buzzwords, or content that does not help the user.
Comfortable operating in ambiguity and turning messy input from founders, product, sales, users, and the market into a clear plan.
Excited about AI engineering and staying close to what developers are actually building.
Experience in developer tools, open source, observability, databases, data infrastructure, cloud infrastructure, AI tooling, or security.
Built or led product marketing at a fast-growing startup.
Managed PMM, DevRel, growth, content, community, or field marketing teammates.
Experience with both self-serve PLG and enterprise sales-assisted motions.
Creates 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.
Knowledge of ClickHouse, SQL, analytics systems, observability, or AI application development.
