ERP Program Manager at Fiserv
The client is undergoing a comprehensive transformation. All SAP ECC landscapes worldwide are being migrated to SAP S/4HANA, with the goal of introducing a global standard template.
The program also includes the migration and modernization initiative "RISE with SAP", which may involve migrating selected country installations to the SAP Private Cloud.
On the stakeholder side, the program's reporting line extends up to the company's board and the implementation partner's board.
Fiserv Germany's ERP landscape currently includes several non-standard SAP tools and applications that extend the ECC environment's functionality and often integrate with downstream systems. As part of the move to SAP S/4HANA, it is essential to assess the core functionality, integration points, and future viability of these applications to determine their alignment with the target architecture.
The focus of the role is to provide expert advice and assessment to define the scope, strategy, and roadmap for migrating Fiserv Germany's SAP ECC system to SAP S/4HANA.
SAP's recommended best practices are followed, and a structured approach is used to ensure a smooth transition with minimal disruption while maximizing business value.
This assessment forms the basis for a successful SAP S/4HANA transformation, ensuring alignment with industry best practices, regulatory compliance, and future scalability.
Migration strategy definition – evaluating available transition approaches based on business objectives, technical feasibility, and SAP best practices.
Technical readiness assessment – conducting a system analysis to assess compatibility, custom code impact, data volume management, integration points, and infrastructure readiness for SAP S/4HANA.
Business process impact analysis – reviewing the latest business process documentation to define the scope and effort needed to implement required functions in SAP S/4HANA and identify process optimization opportunities.
Roadmap for non-SAP systems and applications – evaluating third-party and legacy applications for SAP S/4HANA integration and recommending consolidation, migration, or replacement strategies.
Deployment & implementation planning – defining a phased rollout approach, including project timelines, risk mitigation strategies, and key milestones aligned with business priorities.
The transformation is carried out in phases: the discovery phase leads to the explore phase, which then leads to the design phase and finally to the implementation phase.

About the technology
Mission-Critical Operating System Management
This proprietary operating system is famous for its multi-user, multiprocessing capabilities and unmatched uptime. It is primarily used in industries where system failure is not an option, such as railway networks, nuclear power plants, stock exchanges, and semiconductor manufacturing. Experts in this field ensure that database transactions, batch processing, and real-time operations run without interruption.
Hardware Platform Migrations
A major task for modern enterprise environments is porting legacy workloads to newer hardware. Specialists handle the complex transition of software from historical VAX, Alpha, and Itanium architectures to modern x86-64 virtualized environments. This requires deep knowledge of compilers, binary translation tools, and system-level APIs to preserve application behavior.
Core Ecosystem and Tooling
To maintain and update these robust environments, professional specialists utilize a specific set of tools and languages integrated into the operating system.
- VMScluster software for high availability and shared storage access
- Oracle CODASYL DBMS and Rdb databases for enterprise data management
- DCL scripting for system automation and batch job control
- Compilers for Fortran, COBOL, Basic, C, and Pascal
- ACMS for transaction processing monitoring
Common Architectural Challenges
Organizations running this platform often face challenges related to legacy code integration and modernization. Specialists are brought in to bridge the gap between traditional architectures and modern IP-based networks or web services. They secure network communications using modern encryption protocols, replace obsolete storage arrays, and resolve performance bottlenecks in decades-old database schemas.
Strategic Freelance Engagements
Hiring external expertise is a common strategy when full-time in-house knowledge is retiring or when a specific, time-limited project arises. Freelance professionals provide the specialized skills needed for operating system upgrades, storage migrations, or disaster recovery planning. They allow companies to maintain their trusted systems safely without committing to long-term overhead.
Key Qualifications in Specialists
Distinguished professionals possess a deep understanding of system internals, memory management, and process scheduling. They do not just write scripts; they understand how the operating system interacts with the underlying hardware or hypervisor layers. Strong communication skills are also essential, as these experts must collaborate with modern IT teams to integrate legacy systems into hybrid cloud strategies.
Frequently asked questions
Before you brief your next project: the most common questions about OpenVMS.
Enterprise systems run OpenVMS for applications requiring absolute uptime, high security, and massive clustering capabilities. It is heavily utilized in sectors like manufacturing, healthcare, finance, and defense where unplanned downtime leads to catastrophic business impacts.
A professional working with OpenVMS is usually proficient in classical languages such as COBOL, Fortran, C, and Basic. They also use Digital Command Language for system administration, batch processing, and automation tasks.
Companies often hire specialists to migrate their legacy systems to modern x86-64 servers or cloud hypervisors using emulation or native porting. A qualified OpenVMS expert can transition your environment to virtual machines without losing data integrity or system performance.
Yes, specialists can connect OpenVMS environments with modern cloud applications using standard TCP/IP networking, REST APIs, and modern messaging queues. This allows legacy database transactions to feed real-time analytics engines running in the cloud.
The newer VSI OpenVMS v9 releases introduce native support for x86-64 architecture, making it easier to run the operating system on industry-standard hardware. This release represents a major milestone, allowing companies to exit proprietary hardware maintenance contracts.
Finding permanent employees with this specific skill set is increasingly difficult as the workforce ages. Engaging a freelance OpenVMS specialist allows companies to access elite system administration and migration expertise for targeted projects, upgrades, or emergency support.
You should look for professionals who have managed multi-node VMScluster configurations and executed complex system upgrades. A strong candidate should be able to walk you through their experience with system performance tuning and disaster recovery scenarios.
While older installations require patching, modern versions of OpenVMS support advanced encryption, secure shell protocols, and multi-factor authentication. An expert can secure your legacy network connections and ensure compliance with modern security audits.
The average hourly rate of freelancers who have used OpenVMS in their recent projects is 105 €, which corresponds to a daily rate of about 837 € based on an 8-hour working day.
