Senior Linux Platform / System Engineer – RHEL, PostgreSQL & DB2

Project overview

As part of a comprehensive IT transformation and cloud journey, our client is modernizing its existing system landscape step by step. To provide internal teams with the necessary freedom for parallel migration and transformation projects, external expertise is sought for the ongoing operation and targeted further development of the existing platforms.

Specifically, the focus is on taking over clearly defined technical work packages related to the existing Linux and database environments. The emphasis is on technically maintaining, optimizing, and elevating these platforms to the next level in terms of stability, maintainability, standardization, and automation. Important clarification: Independent responsibility for migration projects is explicitly not part of this role – points of contact with these projects will only arise where adjustments or technical dependencies on the existing platforms need to be considered.

• Utilization: Full-time (Total contingent: 700 hours)
• Project length: 6 months with option for extension
• Location: Approx. 3 days on-site in Wiesbaden for onboarding, thereafter 100% remote
