A Senior Software Engineer role on the commerce platform team at a large building-products distributor. The work centers on designing and building eCommerce services and front-end experiences — including checkout, personalization, and scalable low-latency systems — that serve millions of users across web and mobile. The role suits engineers comfortable across both back-end services and modern front-end frameworks.
Mid level · 2+ years · Full-time
Advertised as Senior, but the requirements read as Mid.
“or” means any one of them counts — you don't need all of them.

Why we read it this way (6)
The posting requires 2–5 years of experience, which aligns with a Mid-level engineer on a normal career ladder. The 'Senior' title is advertised but the experience band and scope do not support it — this is flagged as a mismatch.
Java, Kotlin, and Go are listed as interchangeable OOP language options under the requirements section; Java is used as the primary with Kotlin and Go as alternatives.
React and Next.js are listed together as front-end framework options; TypeScript is listed alongside them but is a distinct technology and is emitted separately.
A Bachelor's degree in CS or Engineering is listed, but the posting explicitly accepts 'equivalent practical experience' as a substitute, so the degree requirement is set to None.
CI/CD, observability, and performance tuning tools appear under a 'Nice to have' / secondary block ('Knowledge of…') and are marked preferred. AI/ML systems and experimentation/recommendation/search technologies also appear in that secondary block.
Commerce, checkout, and personalization system experience is listed in the requirements section but names no specific technology or tool, so it is not emitted as a skill per extraction rules.
