About the Role

Taste Labs is building the data and infrastructure layer for taste, aiming to end AI slop and make AI feel right. The role involves researching grading methods, designing tasks to capture taste and design capabilities, building agent harnesses and context layers, working on scalable RL infra, and collaborating with research teams and frontier labs to improve models.

Responsibilities

  • Research different grading methods and rubrics
  • Design unique tasks that can capture elements of “taste” and design capabilities
  • Build agent harnesses and context layers
  • Work on scalable RL infra
  • Work with internal research teams on our training pipelines
  • Work with the top frontier labs on how to craft environments to improve frontier models

Requirements

  • Experience in building evals, RL environments, ML or post-training
  • Strong backend experience
  • You like ambiguous, hard, creative problems, and want to make subjective domains verifiable
  • You’re a team player and have startup DNA: you move fast, adapt, no such thing is ‘not in scope’, you like to take ownership of things
  • Open source contributions or personal projects that show you build things because you're curious
  • Background at creative companies (Figma, Notion, Canva, Adobe, Runway, etc.) or companies with strong index building/crawling (e.g. Firecrawl, Brave, Luma, Pika) or data (Mercor, Surge, etc.)

Skills

  • Backend development
  • Evals
  • RL environments
  • ML
  • Post-training

About the Company

  • Taste Labs is building the data and infrastructure layer for taste.
  • Our goal is to end AI slop. To make AI feel right, not just be correct.
  • We raised $18.5M in seed co-led by Amplify and CRV, and most frontier labs are already customers.
  • AI has nailed objective domains and can generate anything. The hard part left is judgement: what fits, what feels like you, what's actually GREAT. We're turning that into something measurable, starting with design.
  • We do it on two sides: building the post-training data and RL environments that teach taste to frontier models, and the context and verification tools agents need to produce work that's more creative, more on-brand, more right.
  • If that problem excites you, you'll like it here!
