About the Role

Rippling is building an autonomous operating system for work, investing heavily in enterprise AI. This role focuses on developing purpose-built ML systems that learn from proprietary data to deliver compounding intelligence across all products, powering the fastest-growing product in Rippling's history. As a Senior Machine Learning Engineer, you will own the end-to-end ML lifecycle, partnering with cross-functional teams to make AI agents reliable, accurate, and continuously improving. This is a hands-on role with opportunities to lead technical decisions and influence the team's ML direction.

Responsibilities

  • Own the end-to-end machine learning lifecycle for high-impact AI projects, from problem definition through production deployment and iteration.
  • Design and implement ML systems—including fine-tuned LLMs, RAG, reward models, and multi-agent orchestration—tailored to Rippling's enterprise domain.
  • Build robust evaluation and experimentation capabilities: offline benchmarks, A/B testing, and continuous monitoring of model quality.
  • Develop training pipelines and data flywheels that leverage Rippling's structured data graph.
  • Take ML techniques from research to production: evaluate where RLHF, distillation, structured decoding, and tool-use training can improve model quality, reliability, and efficiency.
  • Build and improve feedback loops, active learning workflows, and automated retraining pipelines.
  • Partner closely with Product and Platform teams to translate requirements into reliable ML systems and deliver measurable product improvements.
  • Contribute to design and code reviews, share ML best practices, and mentor engineers within the team.
  • Stay current with ML research and apply relevant advances to production systems.

Requirements

  • 5+ years of software engineering experience, including 3+ years focused on ML, with experience shipping and operating ML systems in production.
  • Strong practical experience with modern ML, including LLMs, transformer architectures, fine-tuning, and RAG; familiarity with RLHF or related model-alignment techniques.
  • Strong fundamentals in classical ML and statistics.
  • Hands-on proficiency with ML frameworks such as PyTorch or JAX and production ML infrastructure.
  • Experience building evaluation systems for generative AI.
  • Demonstrated ability to independently deliver complex ML projects, make sound technical tradeoffs, and collaborate across functions.
  • Strong product instincts and an ability to connect model improvements to customer outcomes.
  • Clear, precise communication to diverse audiences.
  • Comfort with ambiguity and high velocity.
  • Publications in top ML venues (NeurIPS, ICML, ACL, EMNLP) are a plus.
  • Experience with enterprise data or knowledge graphs is a plus.
