Last position:
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
What HDLC is
HDLC, or High-Level Data Link Control, is a data link protocol used on synchronous serial connections. It defines how frames are built, addressed, checked, and delivered between systems.
It shows up in telecom gear, industrial networks, and legacy WAN setups where stable point-to-point transport still matters.
Common uses
Companies bring in HDLC specialists for work such as:
- framing and deframing serial traffic
- integrating WAN interfaces and leased-line links
- diagnosing drops, CRC errors, and timing issues
- connecting field devices and network appliances
- keeping legacy links running during migration
Tools and stack
Strong professionals know the protocol details and the hardware around it. They often work with router OSes, serial cards, analyzers, and low-level diagnostics.
They should understand bit-oriented framing, control fields, FCS checks, and the differences between HDLC variants used by vendors and carriers.
When to bring in help
HDLC work is often needed when older infrastructure meets new systems. That can mean a migration, a repair, a vendor handover, or a link that only fails under load.
In Germany, these projects often need clear documentation and smooth cooperation with internal network, operations, and field teams.
What good specialists deliver
A strong expert does more than read the spec. They trace packets, isolate link errors, check clocking and encapsulation, and explain what breaks the frame exchange.
Look for careful debugging, clear notes, and the ability to work across hardware, firmware, and network layers.
Typical project fit
HDLC is rarely a greenfield topic. It fits projects where reliability, compatibility, and legacy support matter more than new features.
Good freelancers help with troubleshooting, migration planning, interoperability tests, and documentation for teams that must keep older links stable while modernizing the rest of the stack.
Frequently asked questions
Questions about HDLC? Start with the answers below.
HDLC is used to move data across synchronous serial links with clear frame boundaries and error checking. Companies rely on it in telecom equipment, industrial systems, and other setups where a stable point-to-point link is still in service. It is often part of legacy or embedded network work, not a web or cloud stack.
HDLC is a framing method with strong vendor and carrier history, while PPP is often chosen when the link needs more built-in negotiation and flexibility. In practice, the right choice depends on the hardware, the carrier interface, and what the remote system expects. A good specialist can spot whether the issue is the protocol itself or the vendor-specific variant being used.
A strong HDLC specialist usually understands serial interfaces, router configuration, packet analysis, and low-level troubleshooting. Familiarity with network encapsulation, clocking, and hardware diagnostics is also useful. In many projects, the real value is the ability to connect protocol behavior with the device and line conditions around it.
HDLC work often needs someone who has seen real link problems before, not just the protocol definition. A simple configuration task may be enough for a general network specialist, but recurring frame errors, carrier issues, or vendor interoperability problems call for deeper hands-on experience. The more legacy hardware is involved, the more practical experience matters.
Yes, much of HDLC troubleshooting can be done remotely if the team has logs, interface counters, captures, and access to device settings. On-site support helps when cabling, clocking, adapters, or physical line issues need direct inspection. In Germany, many teams mix remote analysis with on-site checks at plants, branches, or network rooms.
A good HDLC freelancer usually provides clear diagnostics, configuration changes, test results, and concise handover notes. For migration work, they may also document mapping between old and new link settings. The best output is not just a fix, but a stable setup that your internal team can support later.
Look for someone who can explain the protocol in plain terms and tie symptoms to a likely root cause. A strong HDLC specialist tests assumptions, checks counters and captures, and separates framing problems from physical line faults. Good documentation and calm communication matter just as much as technical depth.
High-Level Data Link Control still matters when a new project must connect to existing serial or telecom equipment. It is less about greenfield design and more about compatibility, migration, and keeping older systems reliable. If your environment includes carrier links, embedded devices, or legacy WAN hardware, it can still be very relevant.
