  • 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.

  • 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).
