Senior Database Administrator (PostgreSQL/Oracle) (m/w/d)

If you are looking for a meaningful career where people work and act with passion, rethink the existing and always strive to find the best solution - you have come to the right place. We develop future technologies to relentlessly make supply chains better. 

We are a leader in supply chain software solutions, helping organizations streamline operations, reduce costs, and improve efficiency.

As a Senior Database Administrator, you will be responsible for planning, operating, and continuously improving our database landscape, with a focus on PostgreSQL and Oracle. You will help ensure high levels of performance, availability, security, and automation across on-premises, cloud, and hybrid environments. Working closely with development, operations, and business teams, you will proactively identify improvements, resolve complex database challenges, and support a stable and reliable service. This role combines hands-on database administration with performance optimization, high-availability solutions, security, monitoring, automation, and clear operational documentation.

What a day in the life looks like:

• Administer, configure, upgrade, and maintain PostgreSQL and Oracle databases, including backup and recovery processes.
• Analyze and optimize database performance using execution plans, indexing, bloat and lock management, and wait-event analysis.
• Build and operate high-availability and replication solutions, including Streaming Replication, Patroni, Data Guard, and HAS.
• Implement patches and security measures such as TDE, hardening, and auditing, and conduct regular recovery tests.
• Manage monitoring, capacity, storage, SLA reporting, and database health reporting.
• Automate operational processes using Shell, Python, and Ansible, and create runbooks, playbooks, and post-mortems.

What you bring to the team:

• At least five years of experience as a Database Administrator in enterprise environments, with strong PostgreSQL and Oracle expertise.
• Proven experience with database administration, upgrades, patching, backup and recovery, and performance analysis using tools such as Explain/Analyze and AWR/ASH.
• Practical knowledge of high-availability and replication technologies, including Data Guard, HAS, Streaming Replication, or Patroni.
• Experience with CheckMK monitoring, storage and tablespace management, capacity planning, and structured incident handling.
• Automation skills using Shell and Python, ideally including Ansible, together with foundational knowledge of security and compliance.
• Fluency in German and strong English skills; experience with Oracle AQ, PL/SQL, and Oracle GoldenGate is an advantage.
