Jobbeschreibung

About the RoleJoin a small, engineering-heavy team building the leading open-source LLM engineering platform — think "Datadog for AI applications." The platform helps teams trace, evaluate, and manage prompts across the full LLM development lifecycle, and is trusted by a large and rapidly growing base of developers at startups and Fortune 50 enterprises alike. The company recently joined forces with a major data infrastructure player, enabling it to move even faster on product while staying true to open-source and self-hosting.

As a Product Engineer on the Growth team, you'll own the full funnel — from top-of-funnel awareness through activation, adoption, and expansion — and have real latitude to run bold experiments that directly move the needle on growth.

What You'll Do

• Analytics & data stack: Build and maintain the product analytics infrastructure (e.g. event tracking, BI tooling, columnar databases) to generate deep insights into user behavior and funnel performance.
• Funnel mapping: Define and instrument core funnels for each product feature; make it easy for the team to monitor activation, adoption, and retention.
• Experimentation: Design and run A/B tests and growth experiments — from onboarding flows to in-product nudges — to validate hypotheses and improve key metrics.
• SDK & integration development: Develop and maintain client SDKs and integrations (multi-language, versioned, packaged) that reduce time-to-value for new users.
• Self-serve & activation: Build in-product experiences, guided flows, and documentation hooks that help customers reach their "aha moment" faster with less hand-holding.
• Feature adoption & expansion: Identify and act on opportunities to help customers expand from a single product area to the full platform offering.
• Cross-functional collaboration: Work closely with product, design, marketing, and sales to align on priorities, communicate tradeoffs, and ship impactful work quickly.
• Open-source community: Contribute to open-source workflows and engage with a vibrant developer community building cutting-edge AI applications.

What We're Looking ForRequired

• Based in the EU and able to work EU timezones; willing to be in the Berlin office approximately one week per month.
• Legal authorization to work in the EU without employer sponsorship (no visa sponsorship available).
• Hands-on experience building or integrating LLM-based applications — including prompt management, LLM evaluation, or observability for LLM systems.
• Strong SQL skills and experience querying/analyzing product and usage data in analytical or columnar databases (ClickHouse or similar is a plus).
• Experience instrumenting products for metrics and analytics: event tracking, tracing, and A/B experimentation to drive growth outcomes.
• Experience developing and maintaining client SDKs or integrations — packaging, versioning, multi-language clients, and release management.
• Proficiency with Git-based workflows, code review, CI/CD pipelines, and containerization (Docker).
• Strong product sense and the ability to communicate technical tradeoffs clearly to non-technical stakeholders.
• Comfortable operating with high ownership and minimal supervision in a fast-moving, small team environment.

Nice to Have

• Experience contributing to or maintaining open-source projects and community-driven development workflows.
• Background at companies in the AI/ML tooling, developer infrastructure, or data observability space.

Compensation & Benefits

• Salary: €90,000 – €160,000 per year, depending on experience.
• Equity participation in a high-growth, well-backed company.
• Work with a focused, experienced, and highly collaborative engineering team.
• Opportunity to shape the growth trajectory of one of the most widely adopted open-source AI platforms in the world.
