  • - Own the development and evolution of scalable, reliable, and production-quality front-end code.

  • - Confidence with both frontend languages, like React and TypeScript, and backend languages, like Express, Ruby.
  • - Experience with, or deep curiosity about building AI-augmented workflows (through LLMs, foundation models, agents, or custom tooling).
  • - Builder or entrepreneurial spirit with a passion for exploring personal and creative side projects.
  • - Proficiency in building high-craft front-end experiences and scalable APIs, complemented by a working knowledge of backend infrastructure and deployment workflows.
  • - A strong sense of usability and attention to detail that aligns with Stripe’s design principles.
  • - A champion of “working in the open” who communicates early and often through rapid prototyping, open experimentation, and frequent “show and tell” sessions to drive transparency and alignment across the organization.
  • - You can apply a “product builder” mindset to solve the “last mile” problem: transforming standalone AI experiments into polished, production-ready products that prioritize discoverability and ease of use.
