You’ll work across the stack — crafting responsive, intuitive seller-facing interfaces on the frontend and reliable, high-performance services on the backend. This is an exciting opportunity to own features from the database to the browser, collaborate with experienced engineers, and ship products used by millions of sellers every day.
Design, develop, and maintain full stack features that support the seller experience, from listing creation to order and inventory management.

Develop and maintain backend services and APIs that power seller-facing workflows.
Collaborate with peers and senior engineers to implement scalable, efficient, and maintainable systems across the stack.
Write clean, well-documented, and well-tested code following best practices.
Participate in code reviews and learn from feedback to continually improve.
Troubleshoot and fix issues across the frontend and distributed backend systems in production environments.
Contribute to improving development processes, tooling, and team workflows.
6-Month Accomplishments:
Become proficient with the seller pod’s tech stack, development tools, and codebase across frontend and backend.
Ship production-quality full stack features with guidance from senior team members.
Take ownership of small to medium-sized components or features end-to-end.
Collaborate effectively with Product, QA, and Design teams on feature delivery.
12+ Month Accomplishments:
Independently deliver full stack features from design to production.
Contribute to performance improvements and scalability initiatives on both the client and server side.
