• Checkouts + Payments: Redesign how customers subscribe to Squarespace — from choosing the right plan to checking out with their preferred payment method. This team focuses on creating flexible, transparent purchasing experiences.
• Corporate Applications: Act as internal consultants, creating custom solutions for departments like Marketing, Legal, and Security. From modern web apps to high-volume event pipelines, this team builds the tools that help Squarespace grow from the inside.
  
  

You'll Get To…

• Comfortable working in collaborative environments where feedback is valued
• A degree in Computer Science — or equivalent industry experience that speaks for itself
  
  

Why You'll Love It Here

• You'll work with passionate, thoughtful engineers solving real-world problems.
• You'll shape products used by millions of people around the globe.
• You'll be supported in growing your skills and your career.
• You'll find a workplace that values inclusivity, creativity, and curiosity.
