Sr. Software Engineer II - Catalog

Job Summary:

The Sr. Software Engineer II - Catalog will build and modernize iHerb's product catalog, one of the most business-critical platforms in the company.

Job Expectations:

• Build and ship catalog features end-to-end: API design, business logic, data models, and React UI.

• Participate in the catalog modernization effort, working on the new stack in parallel with the existing platform.
• Write and maintain automated tests; quality is built in, not handed off.
