Senior Data Engineer - Azure Cloud (m/f/d)

You want to build data platforms in Microsoft Azure that make our clients' corporate and machine data usable for analysis and AI – with a clear perspective towards Principal Architect? Then read on.

KRALLMANN AG is a owner-managed family company, founded in 2006 by Prof. Dr. Hermann Krallmann, professor emeritus at the TU Berlin, who is still actively involved today. We offer strategy consulting, AI consulting and implementation, business process management, enterprise architecture management, and software engineering from a single source – scientifically founded and as a partner in research network projects. We combine the organizational, technical, and psychosocial dimensions, because change is only successful if people are on board.

We support well-known clients from logistics, finance, and industry as partners throughout the entire transformation cycle, even beyond go-live. We listen and speak our clients' language. Internally, you can expect flat hierarchies, short decision-making paths, and direct access to the founder.

For our AI & Software Engineering team, we are looking for an experienced individual who will conceptualize, build, and be technically responsible for central data platforms in Microsoft Azure for our clients – from connecting source systems to the finished dashboard. Typical areas of application are with clients from logistics, finance, and industry, such as consolidating corporate and machine data on a common platform. With growing experience, you will develop into a Principal Architect Data & Cloud in your professional career.

These are your tasks

• You will connect corporate systems and machine data via interfaces and model the data so that it is ready for AI applications, analyses, and dashboards.

• You will build the cloud infrastructure for our clients using Infrastructure as Code and automate deployment and operation via CI/CD.

• You will implement security, authorizations, and tenant separation so that each user group sees exactly the data they are allowed to see.

• You will participate in pre-sales, build knowledge within the team, and further develop our data and cloud offerings.

What you bring with you

• Several years of experience as a Data Engineer in the cloud (ideally 4+ years), preferably in Microsoft Azure, with very good knowledge of SQL and Python

• Experience with Infrastructure as Code and CI/CD as well as good knowledge of cloud security and authorization concepts, ideally with Entra ID
