Job Description

• Own the core LLM infrastructure powering two products redefining B2B research: Hub and Prime. • Build self-serve features that compress weeks into days: question → expert insight → follow-up, powered by RAG and adaptive workflows. • Architect automated systems that continuously capture expert opinions—creating longitudinal datasets and refreshable dashboards that compound in value. • Fuse structured survey data with unstructured expert knowledge, build semantic search across proprietary corpora, and create AI pipelines that maintain research-grade quality at scale.

Job Requirements

  • 3-4 years of experience shipping production code in a fast-paced environment
  • Full-stack expertise: Moderate proficiency in React, TypeScript, and modern frontend frameworks.
  • Backend experience with Python, Node.js, or similar
  • AI/ML implementation experience: Hands-on experience integrating LLMs, building with OpenAI/Anthropic APIs, or implementing ML models in production.
  • Experience with AWS, Docker, and modern deployment practices
  • Experience with testing, code reviews, and maintaining high code quality standards
  • Ability to translate user needs into technical solutions while maintaining engineering best practices.

Benefits

  • Excellent medical, dental, and vision insurance.
  • 401k match with immediate vesting.
  • Generous Paid time off, holidays, and parental leave.
  • A diverse, collaborative, and positive culture where we invest in and celebrate each other’s success.
  • Flexible work environment where we work hard but have fun (happy hours, team projects, and retreats).
