• Build and improve APIs used by internal and external customers.

• Participate in architectural discussions and technical decision-making.

• Refactor and optimize existing services.

• Improve performance, reliability, and maintainability.

• Review code and share engineering best practices.

• Collaborate with engineers across multiple product teams.

What You’ll Be Working On

Some of the team’s current initiatives include:

• building and expanding our Public API platform

• improving performance and reducing latency across critical customer journeys

• refactoring cart and checkout services

• improving system observability and metrics

• evolving parts of our monolith into independent services
