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.

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
What CAN Bus does
CAN Bus, short for Controller Area Network, is a message-based communication system for electronic control units. It lets devices exchange data over a shared two-wire network without a central host. CAN Bus is common in passenger vehicles, commercial vehicles, agricultural machinery, robotics and industrial equipment.
Core applications
CAN Bus supports real-time communication where reliability and predictable behavior matter. Typical work includes:
- Connecting ECUs, sensors, actuators and diagnostic tools
- Building vehicle control and monitoring networks
- Integrating battery, motor and charging systems
- Supporting industrial machines and mobile equipment
- Testing fault handling and message timing
Ecosystem and tooling
Strong specialists understand CAN, CAN FD and common higher-level protocols such as CANopen, J1939 and UDS. Their toolkit may include DBC files, bus analyzers, oscilloscopes, logic analyzers, simulators and test automation. They also work with embedded C or C++, microcontrollers, RTOS environments and automotive software interfaces.
When companies need help
Companies often bring in freelance expertise when a new control unit must join an existing network, communication faults are difficult to reproduce or a prototype needs to become production-ready. In Germany, specialists may support automotive suppliers, mobility companies, machine manufacturers and industrial teams remotely, on site or in a hybrid setup. Clear technical English is common, while German can help in plant and supplier collaboration.
What strong professionals deliver
A capable CAN Bus professional begins with the network architecture, message definitions, bitrate and termination. They trace signals from requirements through firmware, wiring and test results. Useful deliverables include DBC specifications, interface documentation, diagnostic services, automated test cases, bus-load analysis and reproducible fault reports. They also account for electromagnetic interference, error states and recovery behavior.
Choosing the right specialist
Look for evidence of hands-on work with the relevant vehicle or machine domain, not only general embedded software experience. Ask how the professional validates arbitration, timing, error frames, termination and compatibility between nodes. Experience with CAN FD, UDS or J1939 matters only when the project requires it. The best fit can explain trade-offs clearly and leave behind testable, maintainable interfaces.
Frequently asked questions
Need clarity? These are the questions we hear most often about CAN Bus.
CAN Bus connects electronic control units, sensors and actuators so they can exchange messages over a shared network. It is widely used in vehicles, industrial machines, robotics, agricultural equipment and battery-powered systems.
Controller Area Network is designed for robust, prioritized message exchange with strong error handling and modest wiring demands. Automotive Ethernet offers higher bandwidth, while LIN is simpler and less costly for lower-speed local devices. The right choice depends on timing, bandwidth, topology and safety requirements.
A strong CAN Bus specialist often also understands embedded C or C++, microcontrollers, RTOS environments, electrical interfaces and automated testing. Experience with CAN FD, CANopen, J1939, UDS, DBC files and tools such as bus analyzers can be important for specific projects.
The right level of CAN Bus experience depends on the assignment. A small integration task may need practical knowledge of message configuration and testing, while a vehicle network redesign requires deeper skills in architecture, diagnostics, timing, error handling and production validation.
CAN Bus development can often be handled remotely when interface files, logs, simulators and test hardware are available. On-site work may still be needed for vehicle trials, wiring checks, electromagnetic testing or access to plant equipment. German and English communication can both be relevant in local supplier projects.
Ask for concrete examples of network integration, fault diagnosis and test evidence involving CAN Bus. A reliable professional can explain bitrate selection, arbitration, termination, bus load, error frames and recovery behavior, then document assumptions and measurable acceptance criteria.
CAN FD is useful when a system needs larger payloads or faster data transfer while retaining the CAN communication model and robust arbitration. It is not automatically the best option: every node, transceiver, toolchain and validation process must support it.
A CAN Bus freelancer may provide network architecture, DBC files, message and signal definitions, diagnostic specifications, test cases, bus-load analysis and fault reports. The deliverables should match the project stage and make the interface understandable, testable and maintainable for the wider team.
The average hourly rate of freelancers in Germany who have used CAN Bus in their recent projects is 85 €, which corresponds to a daily rate of about 683 € based on an 8-hour working day.
Of the freelancers in Germany who have used CAN Bus in their recent projects, 91% hold at least a Bachelor's degree, 70% hold at least a Master's degree, and 10% hold a doctorate.
On average, freelancers in Germany who have used CAN Bus in their recent projects have 21 years of professional experience, with a single engagement typically lasting around 2.9 years.
The most common languages among freelancers in Germany who have used CAN Bus in their recent projects are German (99%), English (97%), and French (18%).
The most common industries among freelancers in Germany who have used CAN Bus in their recent projects are Automotive (81%), Manufacturing (80%), and Information Technology (62%).
The most common business areas among freelancers in Germany who have used CAN Bus in their recent projects are Product Development (100%), Quality Assurance (93%), and Information Technology (86%).
