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 an automotive test bench platform at Automotive supplier
In this project, I was responsible for designing and implementing 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 UML modeling used consistently throughout. This structured approach significantly increased the reusability of individual LabVIEW test modules and sustainably reduced development time for subsequent projects. I also integrated modern automotive standards such as CAN FD, LIN, and safety requirements, making the solution future-proof.

About the technology
Industrial communication
PROFINET is an Industrial Ethernet standard for real-time communication between controllers, remote I/O, drives, sensors and other automation devices. It supports structured data exchange, diagnostics and coordinated control in production systems. The technology is widely associated with Siemens SIMATIC and the broader PROFIBUS & PROFINET ecosystem.
Network design
Strong specialists plan the physical and logical structure of a PROFINET installation. They select suitable switches, define device names and IP settings, segment traffic where needed, and document topology for commissioning and maintenance. They also account for electromagnetic conditions, redundancy needs and the timing demands of motion or process applications.
Tools and ecosystem
PROFINET work often involves TIA Portal, SIMATIC controllers, ET 200 remote I/O, HMI systems, drives and industrial switches. Professionals may also use GSDML files, controller diagnostics, packet captures and vendor-specific engineering tools. Adjacent knowledge of PROFIBUS, OPC UA, PLC programming, industrial cybersecurity and functional safety is valuable when systems span several automation layers.
Typical assignments
- Design or extend a PROFINET network for a new production line
- Integrate controllers, remote I/O, drives, robots and machine vision
- Commission devices and resolve name, topology or configuration faults
- Diagnose cycle-time, packet-loss and intermittent communication issues
- Migrate or connect existing PROFIBUS installations with newer systems
When expertise matters
Companies bring in freelance PROFINET specialists during plant expansions, machine integration, commissioning and brownfield modernization. External support is useful when an internal team needs focused troubleshooting without delaying production. In Germany, on-site work may be important for factory acceptance tests, cabinet checks and commissioning, while planning, documentation and many diagnostic tasks can be handled remotely.
Quality indicators
A capable professional explains how a network design supports the required real-time class and shows disciplined commissioning practices. They verify device identity, topology, diagnostics, cable infrastructure and controller behavior instead of treating symptoms in isolation. Ask for examples of comparable machines or plants, clear test records and a practical handover plan for the operating team.
Frequently asked questions
Everything clients usually want to know about PROFINET, in one place.
PROFINET connects controllers with devices such as remote I/O, drives, robots, HMIs and sensors over Industrial Ethernet. It carries cyclic control data as well as diagnostics and configuration information. This makes it suitable for discrete manufacturing, process-related systems and automated material handling.
PROFINET uses Industrial Ethernet and supports higher network flexibility, richer diagnostics and direct integration with modern IT and automation systems. PROFIBUS is a fieldbus technology that remains common in existing plants. The right choice depends on installed equipment, timing requirements, migration goals and the condition of the current infrastructure.
A strong PROFINET professional usually understands PLC programming, TIA Portal, Siemens SIMATIC hardware, industrial switches and GSDML device descriptions. Knowledge of PROFIBUS, OPC UA, VLANs, network diagnostics and industrial cybersecurity can be equally important. Experience with drives, robotics or safety systems is useful for integrated production lines.
The required depth depends on the assignment. A device integration may need focused configuration skills, while a plant-wide redesign calls for experience with topology, redundancy, commissioning and fault analysis. Ask candidates to describe comparable machines or facilities and the exact deliverables they owned.
PROFINET planning, configuration reviews, documentation and some diagnostics can often be handled remotely. Physical commissioning, cable checks, machine acceptance and intermittent fault investigation may require access to the site. For German facilities, clarify travel expectations, site safety rules and the working language before the engagement begins.
Check whether the professional has worked with the controller, drives, I/O and switches used in your plant. Ask how they document topology, device names, diagnostic findings and recovery steps. A good specialist links each recommendation to production risk and leaves the internal team with maintainable records.
PROFINET faults can result from poor cabling, duplicate device names, incorrect topology data, unsuitable switches, electromagnetic interference or configuration mismatches. Symptoms may appear only under production load or after a machine change. Effective diagnosis combines controller alarms, device diagnostics, physical inspection and packet or topology analysis.
Freelancers working with PROFINET should follow updates from PROFIBUS & PROFINET International and stay familiar with current Siemens and other vendor tooling. Hands-on practice with diagnostics, device integration and commissioning matters more than tool familiarity alone. Documented lessons from varied plant environments also strengthen their ability to assess unfamiliar systems.
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.
Of the freelancers in Germany who have used PROFINET in their recent projects, 75% hold at least a Bachelor's degree, 42% hold at least a Master's degree, and 4% hold a doctorate.
