About Us / Project Context

Our DBaaS (Database as a Service) team operates a central platform for automated provisioning and management of databases across multiple environments (e.g., AWS, GCP) and various DBMS (Oracle, PostgreSQL).

Current setup:

• Database provisioning (create, modify, delete) is handled via CI/CD pipelines in GitLab
• A central Self-Service Portal serves as the user interface and triggers these processes
• The portal also provides features like billing, data maintenance, and integration with a central data inventory
• These additional functions communicate with other systems and portals via APIs

Technical background of the existing solution:

• The current portal is based on an Oracle database with Oracle APEX frontend
• Core business logic is mostly implemented in PL/SQL within the database
• There is an existing Node.js/microservice layer, but it primarily acts as a forwarding layer to the database logic
• The existing platform is maintained and further developed internally, and this role will not be responsible for it

WHAT WILL YOU DO:

• Develop a modern DBaaS platform in parallel with the existing system, with the goal of fully replacing it once complete
• Port and re-implement existing functionalities into a modern, service-oriented architecture
• Work on a new platform based on:
  • Node.js backend (running in Docker containers on Kubernetes / CaaS)
  • Frontend preferably using Vue.js, React is also possible
  • PostgreSQL database
• Develop and integrate API-based interfaces to internal and external systems
• Collaborate on CI/CD topics with DevOps teams (not a main focus)
• Work closely with DevOps and cloud teams

Technology / Stack

• Backend: Node.js (JavaScript)
• Frontend: Vue.js (preferred), React optional
