Built to change the nature of grocery ecommerce globally, our custom-designed solutions are uniquely capable of meeting the complex and developing expectations of shoppers, while driving better productivity, greater flexibility, and higher margins for grocery retailers online.

The goal of the project is to keep the Web system reliable and resilient, reducing risks, improving performance to deliver the best UX for customers. We also aim to make the platform compliant to industry standards, while developing new features.

The candidate will join a new project in a fast-paced Agile team. Among the main responsibilities are the development of new features, requirements analysis, and applying the best IT practices as part of their daily routine.

Cross-team support within the project:

•  Java 11 migrations (to be confirmed, most services seem to be already migrated)

•  RDS migration: migration of version of Postgres in AWS RDS for several of our microservices

•  Migration of internal frameworks: Spring Boot, AWS client libraries, security updates, etc.

•  Data migration: new retailers coming to our platform may need to have their data in their current production systems migrated to the OSP services

•  Work with the SRE team to ensure support and update dependencies of services that don’t change often. Some of these services are in the area of “Customer Audit” or “Right to be forgotten”.

We hire people not for a project but for the company. If the project (or your work on it) is over you go to another project or to a paid “Idle”.
