  • Experience with Python
  • You are proficient in web design: HTML, CSS, Design systems with a portfolio to show it
  • You are proficient in data plumbing in React: GraphQL, fetch, Apollo, React Query, or similar

  • Comfortable with ambiguity, lack of structure, and a greenfield environment where you can (and have to) build a lot from scratch

Additionally, here are some general skills that LabelFlow people tend to have

  • You are fluent in English
  • You are very curious and won't stop searching until you find the answer
