Plum Inc is hiring a Senior Data Scientist

About the Role

Shape the future of AI-driven fintech by leading the design and implementation of scalable Generative AI systems. In this role, you'll architect end-to-end pipelines that leverage large language models to process complex data and deliver contextually relevant results across client-facing products.

What You’ll Do

  • Design and maintain robust Generative AI workflows using LLMs, from data ingestion through to generation and deployment
  • Integrate both open-source and proprietary models—including GPT and LLaMA—using APIs and custom orchestration layers
  • Build and refine Retrieval-Augmented Generation (RAG) systems to enhance prompt relevance with contextual data
  • Develop evaluation frameworks that combine embedding-based similarity, scoring metrics, and human feedback to assess output quality
  • Implement monitoring and logging solutions to ensure reliability and observability in production environments
  • Collaborate with cross-functional teams to embed generative capabilities into live applications

What We’re Looking For

  • Proven experience in machine learning with a focus on production-level systems
  • Hands-on work across the full ML lifecycle: retrieval, generation, evaluation, and deployment
  • Strong technical fluency with tools like LangChain and architectures such as RAG
  • Ability to thrive in a fast-moving, autonomous environment where ownership and innovation are central

Environment & Culture

This is a fully remote role with team members across the U.S., offering long-term flexibility and autonomy. You’ll work within a high-performing, collaborative culture that values initiative, technical excellence, and meaningful impact. Regular video meetings and digital collaboration via Slack keep the team connected. Occasional in-person gatherings provide opportunities to strengthen relationships and align on vision.

The organization emphasizes ownership, continuous learning, and direct contribution—your ideas won’t just be heard, they’ll be acted on.
