    Your role in the team

    • Full-Stack development and technical responsibility for the VuFind implementation. This includes modifications in the PHP backend, VuFind modules, and Solr definitions, as well as the associated data provisioning pipelines.
    • Backend development and customization: You develop the backend logic of our new discovery system VuFind based on PHP.
    • Data integration and API management: You design and implement interfaces (REST, OAI-PMH, etc.) for connecting library management systems (e.g., Alma), repositories, and external data sources.
    • Search engine technology: You optimize and configure the indexing and search logic in Apache Solr.
    • Architecture and Deployment: You design the target architecture in collaboration with the operations managers and make decisions regarding the technical framework of a multi-tenant system.
    • Code quality: You establish clean and well-testable development practices within the core team. This includes sustainable software architecture, quality assurance through internal reviews, and automated deployments via CI/CD pipelines.

    Our expectations of you

    Education

    • Several years of practical experience as a Full-Stack Developer, whether through formal education, studies, or an alternative path. What matters is what you have built, maintained, and operated productively.

    Qualifications

    • Analytical foresight: You are not afraid of complex, hierarchical data structures (e.g., XML, JSON, or library formats such as MARC21 or Dublin Core).
    • Frontend technologies: Knowledge of JavaScript/HTML5/CSS3 to support and coordinate with the frontend is a big plus.
    • You have the ability to convey complex technical issues and can translate requirements into clear technical solutions together with subject matter experts, working towards a common goal.
    • Previous library experience is not a requirement but is advantageous.
    • Very good German skills and technical English

    Experience

    • Extensive experience in server-side development with PHP: ideally with current frameworks such as Laminas or Laravel – or proven solid experience in a comparable environment and the willingness to quickly and thoroughly familiarize oneself with the required programming languages.
    • Data and search know-how: practical experience with relational databases (e.g., MariaDB, MySQL) and ideally some initial exposure to search engines like Apache Solr or Elasticsearch are a definite plus.
    • Proficient in DevOps tools: experience with Git-based workflows and CI/CD, Linux environments, package managers, and Kubernetes.
