Head of Marketing, Langfuse

About Langfuse Langfuse is the open-source LLM engineering platform that helps teams build useful AI applications through tracing, evaluation, prompt management, datasets, and metrics. We are now part of ClickHouse. Like ClickHouse, Langfuse is open source, and we work in public: our product, docs, changelog, roadmap, and community discussions are visible to the developers and teams who use us. Langfuse is already one of the most widely adopted platforms in the category: trusted by 19 of the Fortune 50 and 63 of the Fortune 500, with 50M+ SDK installs per month, 6M+ Docker pulls, and 30k+ GitHub stars. We are hiring a Head of Marketing for Langfuse. This is a hands-on marketing leadership role for someone with deep experience in product marketing, developer marketing, and technical content. You will own how Langfuse shows up in the market, manage the Langfuse marketing team, and turn our current founder-led, product-led motion into a holistic marketing ecosystem. The core of the role is still product marketing and developer trust: positioning, launches, category narrative, developer content, website, customer proof, lifecycle, funnel, sales enablement, and the way we explain Langfuse to technical users and technical buyers. At the same time, Langfuse now has access to ClickHouse's global go-to-market engine. You will be the person who makes those resources work for Langfuse without diluting the Langfuse voice. What You'll Do: Own Langfuse marketing strategy and execution globally, with product marketing and developer content as the center of gravity. Manage and develop the Langfuse marketing team, including Product Marketing Engineering, Developer Advocacy, and Product Marketing content and resources. Define the operating model for Langfuse marketing: what sits in the Langfuse pod, what runs through ClickHouse shared teams, who owns what, and how we measure whether it is working. Build the marketing plan across positioning, launches, website narrative including product pages and conversion paths, customer proof, onboarding, lifecycle, funnel, sales collateral, campaigns, and events. Own the Langfuse category narrative: LLM observability, evals, prompt management, datasets, agent observability, self-hosting, and the broader LLM engineering workflow. Keep the developer motion strong: useful technical content, examples, cookbooks, docs-adjacent education, changelog, town halls, open-source communication, and high-trust product launches. Partner with ClickHouse demand generation and field marketing to make enterprise marketing systematic rather than ad hoc: webinars, workshops, regional events, conferences, paid campaigns, retargeting, and follow-up motions. Create the canonical Langfuse sales narrative and enablement system so ClickHouse AEs, SAs, field teams, and leadership can confidently explain Langfuse. Lead customer marketing and proof: case studies, technical stories, customer references, logo strategy, community stories, enterprise migration stories, and reusable sales narratives. Use data to run the function: unique visitors, signups, activation, revenue, product usage signals, campaign performance, attribution, event ROI, pipeline creation, pipeline acceleration, and qualitative user feedback. What You Bring Along: You have led product marketing, developer marketing, DevRel, growth, or demand gen marketing for a technical SaaS product. You have marketed to developers, infrastructure teams, AI teams, data teams, security teams, observability teams, or another highly technical audience. You are a strong product marketer at the core: positioning, narrative, launch strategy, competitive thinking, customer proof, sales enablement, and technical buyer messaging are natural territory for you. You write exceptionally well. You can make complex technical ideas clear without making them shallow. You are technical enough to use the product, understand the market, earn credibility with engineers, and spot vague or misleading market
