Our client is one of the biggest online retailers worldwide with yearly revenue of £1 billion. 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. Making platform compliant to industry standards and develop new features.
The Java Engineer will join a new project in a fast-paced agile team based in Lublin. 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.
