• Develop and implement scalable database designs that meet business needs • Optimize and tune databases for performance, including query optimization, indexing strategies, and troubleshooting performance issues • Ensure data integrity and security by implementing best practices for backup, recovery, and access control • Work closely with developers, data scientists, and other stakeholders to understand data requirements and deliver solutions that align with project goals • Provide guidance and support to junior database engineers and other team members • Stay current with emerging database technologies and trends • Diagnose and resolve complex database issues

• Architect & build core backend systems. • Design scalable data infrastructure. • Integrate AI into real-world workflows. • Design systems that scale. • Develop performant APIs and services. • Collaborate closely with users. • Shape Clipbook's engineering culture.

• As a PHP developer you are part of our backend team and collaborate with colleagues from other software areas to further develop our platform. • You design new features on our existing Yii-based site, contribute to our new Symfony developments and actively help migrate the monolith to a service-oriented architecture. • You further develop existing Transfermarkt features and initiate new ones – both in the monolith and in the new Symfony stack. • You build robust REST APIs that connect our web and app projects. • You coordinate closely with stakeholders, for example on API design or integrating external services. • You work in a growing system that handles many millions of requests per day – performance, scalability and clean architecture are a key focus. • You build it, you run it: your interest goes beyond software development and you are also curious about how the application behaves in production, how it is monitored and how it can be improved. • You develop within an agile Scrum process in two-week sprints and actively participate in reviews, retrospectives and technical improvements.

• Take ownership of the conception, implementation, documentation, and architecture of features, interfaces, and sub-systems. • Work closely with architects, developers, and business roles in a cross-functional agile team. • Actively drive and shape the products daily. • Successfully lead an initial integration project (HL7 or FHIR) across the finish line. • Deliver reliably — with over 90% of development tasks completed on time. • Take ownership: of features, releases, and writing clean, traceable code. • Help improve CI/CD processes, increase test coverage, and bring fresh ideas for standards and interfaces. • Share knowledge by mentoring junior developers.
