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
What CAN Bus does
CAN Bus, short for Controller Area Network, is a robust serial communication system for microcontrollers and electronic control units. It lets distributed components exchange messages without a central host, using priority-based arbitration and strong error detection. The protocol is widely used where reliable communication matters in vehicles, machines and embedded products.
Systems and use cases
CAN Bus supports real-time data exchange across environments with electrical noise, limited wiring and strict reliability needs. Typical applications include:
- Powertrain, chassis and body control networks in passenger and commercial vehicles
- Industrial machines, robots and mobile equipment
- Battery management, charging systems and energy hardware
- Medical devices, lifts and safety-related control systems
- Test benches, gateways and diagnostic tools
In Germany, it is common across automotive manufacturing, suppliers, automation and industrial equipment projects.
Protocols and tooling
CAN specialists work with the ISO 11898 standard and practical ecosystem layers such as CANopen, SAE J1939, DeviceNet and NMEA 2000. They select transceivers, configure bit timing, define message identifiers and map signals into usable data models. Tooling can include CAN analyzers, bus monitors, oscilloscopes, hardware interfaces and software libraries for embedded or desktop systems.
Integration skills
Effective CAN Bus work combines embedded firmware, electronics, diagnostics and systems integration. Specialists may connect CAN networks with Ethernet, LIN, FlexRay, USB or cloud services through gateways. They also handle bootloaders, calibration data, fault handling, network management, cybersecurity controls and automated testing, depending on the product and its safety requirements.
When companies need help
Freelance expertise is useful when an internal team must bring a prototype into reliable operation, investigate intermittent bus faults or extend an established network. Common signals include:
- Unclear message specifications or conflicting signal definitions
- Bus-off events, frame errors or unexplained latency
- A new ECU, sensor, actuator or gateway must join the network
- Diagnostic data needs to align with vehicle or machine requirements
- Existing firmware requires testing, documentation or modernization
For projects in Germany, remote analysis can often be combined with on-site work at a lab, plant or vehicle facility.
What strong experts deliver
Strong CAN Bus professionals explain trade-offs in identifiers, timing, termination and network load before implementation begins. They use traces and reproducible tests to isolate faults instead of relying on assumptions. Their deliverables may include message databases, interface specifications, firmware, diagnostic procedures, test reports and clear documentation for production and maintenance teams.
Frequently asked questions
Need clarity? These are the questions we hear most often about CAN Bus.
CAN Bus connects electronic control units and embedded devices so they can exchange short, prioritized messages over a shared network. It is used in vehicles, industrial machinery, battery systems, medical equipment and test environments where robust communication is required.
CAN Bus is often chosen for dependable control communication with moderate bandwidth and distributed arbitration. LIN is simpler and less costly for low-speed peripherals, FlexRay supports more deterministic communication, and automotive Ethernet offers much higher bandwidth for data-heavy systems.
A strong CAN Bus specialist often combines embedded C or C++, microcontroller firmware, electronics, diagnostics and test automation. Experience with CANopen, J1939, gateways, signal databases, oscilloscopes and network analysis tools is also valuable.
The right level of CAN Bus experience depends on the risk and scope of the system. A simple interface integration may need a specialist who can configure messages and test signals, while safety-critical vehicle or machine networks require proven skills in architecture, fault analysis, diagnostics and verification.
CAN Bus development can often be done remotely when specifications, logs, simulation models and hardware access are available. On-site collaboration in Germany may still be important for vehicle testing, production equipment, laboratory measurements or faults that cannot be reproduced elsewhere.
A company may bring in a CAN Bus freelancer when a project faces intermittent bus errors, an urgent integration issue or a gap in protocol knowledge. External specialists can also review an architecture, create a test strategy or prepare a team for a new CANopen or J1939 implementation.
Ask a CAN Bus professional to explain how they would verify bit timing, termination, arbitration, error states and message definitions. Strong specialists can show a methodical approach using traces, fault injection, reproducible tests and documentation rather than treating the network as a black box.
A capable CAN Bus specialist may deliver message and signal specifications, database files, firmware changes, gateway mappings, diagnostic procedures and automated tests. For production work, request clear records of assumptions, error handling, verification results and any limits found during bus analysis.
The average hourly rate of freelancers in Germany who have used CAN Bus in their recent projects is 86 €, which corresponds to a daily rate of about 686 € based on an 8-hour working day.
Of the freelancers in Germany who have used CAN Bus in their recent projects, 92% hold at least a Bachelor's degree, 72% 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 (98%), and French (18%).
The most common industries among freelancers in Germany who have used CAN Bus in their recent projects are Automotive (81%), Manufacturing (81%), 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 (94%), and Information Technology (87%).
