Jens R.
Last position:
Platform Architect & Senior Developer at Direct client, industrial measurement technology, medium-sized company
- Technical leadership across hardware, firmware, and software teams; scope: hardware/firmware team (4 people) and leadership group (5 people)
- Consolidated and documented a product family that had grown over more than 15 years and aligned it with CRA compliance — from the bare-metal I/O module to the cloud interface.
- Provided the most important customer product with the essential requirements and architecture documentation within two months — for a firmware landscape that had grown over more than 15 years. It now supports the customer’s modernization strategy.
- Established a monthly reporting line to the supervisory board and executive board within three months: nine meetings since 12/2025. The report itself is versioned and built from the CI pipeline; it is based on automatically collected activity and release data instead of assessments.
- Built a container-based CI/CD infrastructure from scratch: cross-compilation, host tests, and documentation builds in one continuous pipeline.
- Introduced declarative QA gates for DevOps and development artifacts — from the start using lefthook instead of pre-commit, executed in a dedicated container image.
Technologies used: arc42, req42, tpo42, docToolchain, PlantUML, ArchiMate, C4 model, ADR, C, C++ (GTest), CMake, Bare Metal (ARM Cortex-M3/M7), OCI containers, Jenkins, lefthook, Prometheus, Grafana, SBOM, CRA, OPC, SCADA, PLC integration, IPv6 migration, Zero Trust, Sociocracy 3.0, Cynefin

Architecture and Programming for Automotive Test Bench Platform at Automotive Supplier
In this project, I was responsible for the design and implementation of a new, modular, and highly scalable test bench platform for an automotive supplier. My focus was on developing a robust system architecture and programming the associated software, with consistent use of UML modeling throughout. This structured approach made it possible to greatly increase the reusability of individual LabVIEW test modules and to significantly reduce development time for follow-up projects. I also integrated modern automotive standards such as CAN FD, LIN, and safety requirements, which made the solution future-proof.

About the technology
Industrial Ethernet for automation
PROFINET, short for Process Field Network, is an Industrial Ethernet standard for connecting controllers, remote I/O, drives, sensors and other automation devices. It supports real-time communication, device diagnostics and coordinated machine control. Companies use it in production lines, process plants, material handling systems and factory-wide automation networks.
Controllers and devices
A PROFINET system links a controller with field devices and engineering tools. Specialists define device roles, network names, addresses and communication relationships, then validate data exchange during commissioning. Common work includes configuring Siemens PLCs, distributed I/O, variable-speed drives, safety components and HMI connections through TIA Portal.
- Configure controllers, devices and GSDML files
- Map I/O and validate cyclic data exchange
- Integrate drives, sensors, robots and HMIs
- Diagnose device faults and communication loss
Ecosystem and tooling
The ecosystem includes Siemens SIMATIC controllers, TIA Portal, PROFINET interfaces, GSDML device descriptions and industrial Ethernet switches. Strong specialists understand RT communication, topology discovery, diagnostics, VLAN concepts and cabling for demanding plant environments. They may also work with PROFIBUS, OPC UA, EtherNet/IP or safety technologies when systems cross technology boundaries.
When freelance expertise helps
Companies bring in freelance PROFINET expertise for new machine builds, line expansions, plant migrations and commissioning under time pressure. External specialists can review an existing topology, resolve intermittent faults or prepare a repeatable automation standard. In Germany, collaboration may combine remote engineering with on-site work at factories, integrators or machine builders.
- Commission a new production cell
- Migrate or extend an automation network
- Investigate jitter, alarms and device dropouts
- Document topology, parameters and recovery steps
Reliable commissioning
Quality work starts with a clear network design and a controlled device configuration. Experienced professionals test communication paths, verify diagnostics and separate wiring, configuration and application faults instead of treating every alarm as a PLC problem. They also document naming, addressing, backups and handover procedures so plant teams can maintain the system.
Choosing the right specialist
Look for practical experience with the controller family, device vendors and engineering environment used in your plant. Ask how the specialist approaches topology reviews, GSDML changes, drive integration, safety boundaries and on-site commissioning. The best fit combines PROFINET knowledge with PLC programming, industrial networking, machine safety awareness and clear technical documentation.
Frequently asked questions
Everything clients usually want to know about PROFINET, in one place.
PROFINET connects industrial controllers with remote I/O, drives, sensors, robots and other automation devices over Industrial Ethernet. It is used for machine control, production lines, diagnostics and coordinated factory automation.
PROFINET uses Industrial Ethernet and supports flexible topologies, higher integration potential and detailed network diagnostics. PROFIBUS remains common in established installations, so a specialist may need to integrate, migrate or troubleshoot both technologies.
A strong PROFINET specialist often combines network configuration with PLC programming, TIA Portal, Siemens SIMATIC systems, drive commissioning and industrial switch setup. Knowledge of PROFIBUS, OPC UA, machine safety and industrial cybersecurity can be important for wider automation projects.
The right level depends on the scope, device mix and commissioning risk. For a simple configuration, focused device and controller knowledge may be enough; complex plants need a specialist who has handled topology design, diagnostics, migrations and production commissioning.
PROFINET planning, configuration reviews, documentation and many diagnostic tasks can be handled remotely with secure access and suitable plant data. Physical wiring, device replacement and final commissioning usually require on-site collaboration, particularly when production equipment is involved.
PROFINET is an open Industrial Ethernet standard, although Siemens tools and controllers are widely used in its ecosystem. Devices from other manufacturers can participate when they provide compatible interfaces and the required GSDML descriptions.
Ask for a clear network design, device inventory, diagnostic method and commissioning plan. Good PROFINET work leaves tested configurations, meaningful device names, fault documentation, backups and handover material that the plant team can use.
A PROFINET freelancer may deliver topology and addressing plans, TIA Portal configurations, GSDML integration, controller and drive commissioning, fault analysis and technical documentation. The exact deliverables should match the plant’s equipment, safety responsibilities and acceptance process.
The average hourly rate of freelancers in Germany who have used PROFINET in their recent projects is 89 €, which corresponds to a daily rate of about 715 € based on an 8-hour working day.
