Jobbeschreibung

In Short: Langfuse is looking for a hands‑on Technical Support Engineer to join the Berlin Office who will own the front line of our customer/community experience, keep a tight feedback loop with product engineering, and help thousands of AI‑product teams succeed with tracing & evals.

About Langfuse

• Open Source LLM Engineering Platform, help teams build useful AI applications via tracing, evaluation, and prompt management (mission, product)

• Massive opportunity, chance to build the "Datadog" of this category; model capabilities continue to improve but building useful applications is really hard, both in startups and enterprises

• Largest open source solution in this category: >2k customers, >14M monthly SDK downloads, >6M docker pulls

• Financials: We raised $4M from world class investors (Y‑Combinator, Lightspeed, General Catalyst) and are default alive by making more money than we spend

• We're a small, engineering‑heavy, focused team in Berlin and San Francisco (how we work)

What you will be working on

At Langfuse support is not a cost‑center but a product discovery engine (see handbook): engineers own their features end‑to‑end, fixes land fast, and users ideally see “magic” when their feedback ships the same day. You will be running that engine while engaging with our large OSS community.

Community and low‑touch Customer Support (70%)

• Triage & solve inbound questions from diverse channels (Slack Connect, email, GitHub, Discord)

• Improve Docs, snippets and auto‑reply prompts so the next 1000 teams self‑serve the answer → ideally users do not have questions and our product/docs are self‑explanatory

• Create helpful content i.e. helpful blog posts, sample repos and tutorials

• Escalate bugs to product engineering and close the loop with the customer once shipped

• Spin up proof‑of‑concepts (TypeScript/Python) to reproduce edge cases or demonstrate work‑arounds

Key Accounts (30%)

• Act as named technical contact for a handful of high‑volume customers; jump on Slack huddles, unblock integrations, surface best practices

• Track their feature requests, quantify impact, and champion them on our roadmap

• Go through deep technical integration/implementation questions together with our customers and in their codebase

Who we are looking for

Must:

• You deeply care about customers and want to help other engineers

• Solid foundations in software engineering (CS or Data Science degree or comparable projects)

• Strong writing: short Slack messages and long‑form guides/documentation

• Curiosity for LLM application development

Bonus:

• Past B2B solutions engineering, technical support, or DevRel

• Open‑source maintainer
