Cloud Engineer – Clustering & Pacemaker Expertise

Overview

Position Overview:
We are seeking a highly skilled Cloud Engineer with specialized expertise in clustering technologies, particularly Pacemaker, along with strong knowledge of hyperscaler platforms (Azure, AWS, GCP, IBM Cloud). The ideal candidate will have deep experience working with Red Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES) and the ability to design and implement high-availability solutions using Pacemaker clustering across multiple OS environments. This role is integral to ensuring the stability and availability of cloud-hosted applications, particularly for SAP workloads, and includes leading proof of concept (PoC) projects, as well as collaborating closely with development teams to prepare requirements and documentation.

Key Responsibilities:Clustering & High Availability Expertise:
Design and implement Pacemaker clustering solutions across multiple operating systems (RHEL, SLES) and platforms to ensure high availability and fault tolerance of critical applications, databases, and services.

Contribute to clustering architecture decisions, ensuring optimal scalability and reliability of business-critical workloads.

Troubleshoot and resolve complex issues related to Pacemaker clusters, providing expert guidance on configuration, failover testing, and cluster architecture.

Hyperscaler Expertise:
Utilize extensive knowledge of hyperscaler platforms (Azure, AWS, GCP, IBM Cloud) to design, deploy, and maintain cloud high availability solutions.

Implement and manage cloud-based HA solutions in multi-cloud environments, leveraging cloud-native services alongside Pacemaker clustering for mission-critical applications.

Proof of Concepts & Architecture Documentation:
Lead and support PoC exercises to evaluate new clustering architectures and solutions, documenting setup, configurations, and lessons learned.

Produce detailed technical documentation covering clustering configurations, architecture diagrams, and deployment processes, ensuring knowledge transfer, reproducibility, and further automation.

SAP Solution Basis & Integration:
Leverage expertise in SAP Solution Basis, specifically SAP S/4 HANA, Netweaver, and HANA databases, to implement and optimize clustering solutions for SAP workloads in the cloud.

Ensure that SAP systems are properly integrated with Pacemaker clustering to meet high availability requirements.

Additional Database Knowledge (Optional):
Support DB2 and other database solutions in the context of clustering and high availability to ensure optimal database performance and uptime.

Collaborate with database teams to implement clustered databases that are tightly integrated with the cloud infrastructure and clustering technologies.

Collaboration & Requirement Preparation:
Work closely with development and business teams to define infrastructure requirements for clustered solutions.

Participate in detailed requirement analysis sessions with internal and external stakeholders to ensure clustering and HA solutions meet SAP ECS needs and requirements.

Communication & Reporting:
Fluent in business English, with the ability to communicate technical concepts clearly to both technical and non-technical stakeholders.

Prepare and deliver technical presentations, status reports, and documentation related to clustering solutions and cloud architectures.

Qualifications:Education:
Bachelor’s degree in Computer Science, Information Technology, or a related field.

Advanced certifications in cloud platforms (Azure, AWS, GCP) and clustering technologies (Pacemaker) are a plus.

Experience:
Multiple years of experience in clustering and high availability solutions, with a deep focus on Pacemaker and associated technologies.

Hands-on experience in cloud environments (AWS, Azure, GCP, IBM Cloud) with a focus on HA architecture and cloud-native services.

Extensive experience with Linux-based operating systems (RHEL, SLES), including system administration and OS tuning in clustered environments.

Technical Skills:
In-depth knowledge and hands-on experience with Pacemaker clustering, including resource agents, fencing, and quorum management.

Strong understanding of cloud platforms (AWS, Azure, GCP, IBM Cloud) with experience in implementing HA solutions.

Experience in deploying and managing SAP systems (S/4 HANA, Netweaver, HANA) in a high-availability clustered environment.

Familiarity with databases like HANA and DB2 (optional) in a clustered and HA setup.

A plus (optional): experience with automation tools (e.g., Ansible).

Soft Skills:
Excellent problem-solving and troubleshooting skills with a focus on complex high-availability configurations.

Strong ability to collaborate with cross-functional teams, providing technical leadership in clustered and high-availability solution design.

Fluent communication skills (verbal and written) in business English, with experience in preparing and presenting technical documentation and reports.

Preferred Skills:
Advanced certifications in Pacemaker, Red Hat, SLES, and SAP systems.

Experience in designing and implementing multi-cloud high availability architectures.
