About The Position

The Sr. Software Engineer II - Catalog will build and modernize iHerb's product catalog, one of the most business-critical platforms in the company. You will work across the full stack: backend services, React frontend, and relational data layers. Our current backend is .NET/C#; we also use Go, Python, and Java across the organization.

Requirements

AI-driven SDLC : hands-on experience shipping production code with AI-assisted development tools such as Claude Code, GitHub Copilot, or Cursor. The bar is not awareness; it is daily use in delivering real software.
Full-stack awareness: comfortable contributing across layers of the stack when needed; purely single-layer specialists are not the target profile.
Production ownership: experience owning features end-to-end from spec through deployment, observability, and on-call. Engineers here own what they ship; there is no separate ops handoff.
Code quality fundamentals: strong grasp of software design principles, automated testing, code review, and CI/CD.
Backend development proficiency in one or more of: C#/.NET, Go, Python, Java. .NET/C# is the primary stack today.
Proficiency in React or equivalent modern frontend framework.
Proficiency in Relational database experience with MS SQL Server or Postgres.
Proficiency in REST API design and microservice patterns.
High degree of accuracy and attention to detail
Excellent organization skills and ability to multi-task

Nice To Haves

Contributions to internal developer tooling, golden path standards, or SDLC process improvements.
Experience with e-commerce platforms, product catalogs, or high-traffic consumer applications.
Experience working in globally distributed teams.
Track record of documenting architectural decisions, writing RFCs, or contributing to engineering wikis.

Responsibilities

Build and ship catalog features end-to-end: API design, business logic, data models, and React UI.
Use AI-driven SDLC tooling such as Claude Code as a core part of your daily workflow, including code generation, spec-to-code translation, and automated test creation.
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.
Review pull requests, maintain code standards, and contribute improvements to the shared golden path.
Collaborate with product and design to refine specs before and during implementation.
Instrument services with logging, metrics, and alerts; participate in on-call rotation and own incident response for catalog services.
