About the Team

At Stripe, we believe that craft and beauty are essential to building tools that people and businesses around the world love and trust. Designers at Stripe sweat every detail, balancing utility, usability, and beauty in everything we ship. These are not just nice-to-have qualities but core to our operating principles and mission. As an AI Staff Software Engineer, you will be the architect of the engine that powers this obsession by designing and building internal AI tools that accelerate prototyping, inspire experimentation and innovation, and get us to production-ready ideas even faster. You must be doggedly curious, technical but creative, deeply familiar with the AI landscape, and obsessed with the ever-changing intersection of code, design, and systems thinking.

What you’ll do

• Partner with designers to understand their workflow and responsibilities and imagine AI-powered tools and agents that left-shift and accelerate prototyping.
• Own the development and evolution of scalable, reliable, and production-quality front-end code.
• Create documentation and workflows that help teams adopt and master these tools quickly and efficiently.
• Write clean, maintainable software that works within Stripe’s stack.
• Drive technical decisions and implementation from start to finish and through support and iteration.
• Ensure all tooling meets Stripe’s expectations around quality, security, and performance.

Who you are

• 10+ years of experience coding production-ready software. 
• 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.
