About the Role Join 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. 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.

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).
