Staff Software Engineer - AIMarketingSan Francisco, CA

Staff AI/ML Engineer

Rippling gives businesses one place to run HR, IT, and Finance. It brings together all of the workforce systems that are normally scattered across a company, like payroll, expenses, benefits, and computers. For the first time ever, you can manage and automate every part of the employee lifecycle in a single system. Based in San Francisco, CA, Rippling has raised $1.4B+ from the world's top investors—including Kleiner Perkins, Founders Fund, Sequoia, Greenoaks, and Bedrock—and was named one of America's best startup employers by Forbes. We prioritize candidate safety. Please be aware that all official communication will only be sent from @Rippling.com addresses.

The Growth Engineering team builds world-class products, data infrastructure, and AI systems powering Rippling's market intelligence and GTM operations. The team works cross-functionally with sales, marketing, Applied AI, and data engineering teams to design systems that amplify Rippling's high-performance GTM engine — from recommendation models and enrichment pipelines to AI-driven workflows and proprietary data funnels. We operate on a modern Growth Services infrastructure built on FastAPI, Kubernetes, Databricks, Kafka, Snowflake, PostgreSQL, and OpenAI APIs, enabling scalable experimentation and fast iteration.

We're seeking a Staff AI/ML Engineer to architect and lead development of production-grade AI systems, including recommendation engines, multi-LLM architectures, and ML pipelines. You'll be responsible for designing systems that combine real-time data processing, ML/LLM Ops, and intelligent orchestration across Rippling's Growth Infrastructure. This is a hands-on engineering leadership role — you'll own the technical strategy for AI/ML within Growth Engineering, mentor engineers, and solve some of the most complex challenges in production AI systems with immediate business impact.

Expertise in recommendation engines, matrix factorization, and personalization models.

Deep experience integrating LLMs (OpenAI, Claude, etc.) into production applications.

Hands-on experience training, evaluating, and deploying models in Databricks notebooks and Spark pipelines.

Experience with MLOps tooling for off-the-shelf models like XGBoost, CatBoost, or LightGBM.

Strong background in data engineering (Kafka, Spark, Databricks, PostgreSQL).

Proven ability to architect scalable AI systems and lead end-to-end deployment.

Preferred Skills

Familiarity with LangChain, LangSmith, and vector databases.

Deep understanding of multi-LLM coordination patterns, dynamic prompt routing, and evaluation loops.
