Project description:

Our client is one of the largest e-commerce platforms in Europe, used by millions of users every day. The company connects sellers - from small businesses to global brands - with customers, offering a vast product selection, fast delivery, and a well-crafted shopping experience.

Designing a vertical-specific user experience for the automotive category as part of company’s key strategic initiative, aimed at transforming the platform from a general-purpose marketplace into a collection of specialized “stores within a store.”

The role:

• Design, develop, and maintain scalable backend services and APIs using Kotlin, Java, and Spring Boot.
• Build and evolve solutions based on microservices architecture, ensuring their reliability, performance, and maintainability.
• Design the architecture of new modules and backend components and contribute to key technical decisions.
• Continuously optimize and improve existing systems, identifying opportunities to enhance performance, scalability, and code quality.
• Work with MongoDB, Spring Data MongoDB, and Google Cloud Platform (GCP) as part of the application ecosystem.
• Write and maintain high-quality, well-tested code while following established engineering best practices.
• Use AI-assisted and agentic coding tools as part of the daily software development workflow.
• Collaborate closely with Product Managers, Data Analysts, UX Designers, and other engineers to translate product and business needs into effective technical solutions.
• Occasionally contribute to areas beyond the backend, including web or mobile development, depending on project needs.
• Ability to effectively use AI-assisted development tools, such as GitHub Copilot, OpenCode, or other agentic coding tools, as part of your daily development workflow.
• Strong proficiency in both Kotlin and Java.
• Hands-on experience in developing backend applications using Spring Boot.
• Experience in designing and implementing solutions based on microservices architecture.
• Strong focus on building, testing, and maintaining high-quality backend services and APIs.
• Ability to design the architecture of new modules and proactively identify opportunities to optimize and improve existing systems.
• Experience working closely with product and business teams, including Product Managers, Data Analysts, and UX Designers, to define and refine technical and functional requirements.
• Strong understanding of software engineering best practices and commitment to maintaining high engineering standards.

Nice to have:

• Versatility and cross-functional skills – hands-on knowledge of frontend or mobile technologies (Web / iOS / Android) at a level that allows you to take on tasks beyond the backend domain.
• Intermediate knowledge of MongoDB and Spring Data MongoDB.
• Hands-on experience working with cloud platforms, with a particular focus on Google Cloud Platform (GCP).
