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
Arista in practice
Arista is used to build fast, stable network layers for data centers, campuses, and cloud-connected offices. Teams choose it when they need predictable switching, clean automation, and clear operations across many devices. The ecosystem is centered on Arista Networks hardware and EOS.
Typical work
- Spine-leaf design and switch onboarding
- EOS configuration, upgrades, and rollback planning
- EVPN-VXLAN design for segmented environments
- Automation with Python, APIs, and config templates
- Troubleshooting routing, overlays, and link issues
What strong specialists know
Good professionals do more than set ports and VLANs. They understand routing, BGP, MLAG, network segmentation, and how Arista EOS behaves in production. They also document changes clearly, because network work affects many teams at once.
When companies bring in freelance help
Companies usually need freelance support for migrations, expansions, or hardening work that cannot wait for a long internal search. In Germany, that often means helping distributed teams align on design, naming, and change windows across sites. Freelancers are also useful when the in-house team needs short-term depth on EOS or automation.
Tools and ecosystem
Arista projects often include EOS, Arista CloudVision, APIs, Python scripts, and integration with monitoring or inventory tools. Strong specialists can move between CLI work and automation work without losing control of the design. They know how to keep operations consistent while the environment grows.
How to judge fit
Look for people who explain trade-offs in simple terms and can show past work on real network changes. A solid Arista specialist will talk about failure domains, upgrade paths, and how to keep traffic flowing during change. For remote work, clear diagrams and good documentation matter; for on-site work, expect close coordination with local operations teams and German-speaking stakeholders when needed.
Frequently asked questions
Everything clients usually want to know about Arista, in one place.
Arista is used for data center switching, campus networking, and network automation where stable, low-latency transport matters. Many teams also use Arista EOS to standardize operations across large switch estates. It is a strong fit when you need clear control over design, rollout, and day-two work.
Arista usually refers to the vendor and its switching ecosystem, while Arista Networks is the company name and EOS is the operating system on the devices. Searchers often use all three terms when looking for the same kind of specialist. In practice, the distinction matters when you need help with hardware, operating system behavior, or automation around both.
Arista is often chosen for modern data center designs, operational simplicity, and automation-friendly workflows. Compared with Cisco or Juniper, the right choice depends on the existing network, team skills, and how much standardization you need. A good specialist can explain where Arista fits without forcing a vendor-first answer.
A strong Arista specialist usually knows routing, BGP, VLAN design, EVPN-VXLAN, and troubleshooting at layer 2 and layer 3. Python, APIs, and config automation are also valuable because many Arista environments depend on repeatable change. Knowledge of monitoring, documentation, and change control helps too.
A Arista project can benefit from freelance help as soon as the work involves migration risk, multi-site coordination, or automation you cannot absorb quickly in-house. You do not need a full rewrite or a crisis to justify support. The best time is often before the rollout starts, when design choices are still open.
Yes, much of Arista work can be done remotely from Germany if the team can share diagrams, access, and change windows clearly. Remote specialists can handle design reviews, automation, and troubleshooting with the right permissions. On-site time becomes more useful for cutovers, lab validation, or sensitive production changes.
With Arista, good quality means the network change is understandable, repeatable, and safe to operate after handover. Look for clean documentation, sensible rollback plans, and config that matches the design instead of one-off fixes. A strong specialist leaves the team able to run the environment with less friction.
A Arista freelancer should ask about the current topology, the EOS version in use, automation tools, and who approves changes. It also helps to know whether the work is a migration, a new build, or a cleanup of an existing environment. Clear access and a named contact make delivery much smoother.
