What you'll build

Deliver significant features and enhancements across Shopper Technology products. Scale high‑traffic digital commerce experiences. Solve challenges that span frontend applications, APIs, microservices, and infrastructure. Improve performance, reliability, security, and developer productivity. Identify and resolve scalability and operational issues across production services. Contribute to engineering best practices and the adoption of AI‑assisted development. If you've worked in a role where you delivered production‑grade JavaScript or TypeScript applications, built and supported GraphQL, REST, or microservice architectures, and implemented CI/CD pipelines or Infrastructure as Code solutions, you'll feel at home here. What matters most is a track record of improving software quality, operating large‑scale systems, and helping other engineers succeed.
