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.

- 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

About the technology
Deterministic Real-Time Kernel Development
FreeRTOS provides a microkernel architecture designed for resource-constrained microcontrollers. Embedded professionals utilize this real-time operating system to handle preemptive multithreading, task scheduling, and inter-task communication via queues, semaphores, and direct task notifications in low-memory environments.
Industrial and Automotive Applications in Germany
German engineering firms rely heavily on the real-time kernel across industrial automation, robotics, medical devices, and automotive subsystems. Local manufacturing standards often mandate deterministic execution alongside functional safety derivatives such as SafeRTOS, requiring specialized knowledge of strict hardware timing and memory isolation.
Typical Hardware Targets and Tooling
- ARM Cortex-M microcontrollers from STMicroelectronics, NXP, and Renesas
- Espressif ESP32 chips leveraging dual-core SMP configurations
- Debugging with Segger J-Link, Ozone, and FreeRTOS-aware GDB plugins
- Static analysis tools ensuring MISRA C compliance
Connectivity and Cloud Integration
Modern deployments frequently employ the AWS IoT FreeRTOS distribution to link edge devices securely to cloud infrastructures. Specialists integrate core libraries such as coreMQTT, coreHTTP, and cellular or Wi-Fi connectivity stacks, while configuring TLS layers and secure bootloaders for robust over-the-air firmware updates.
Indicators That Specialized Support Is Needed
- Unresolved priority inversions causing silent deadlocks under operational load
- Memory fragmentation issues exhausting heap managers like heap_4 or heap_5
- Strict power budgeting requiring dynamic tickless idle implementation
- Porting legacy bare-metal C codebases to modular multi-task architectures
Evaluating Practical Technical Proficiency
A proficient specialist understands hardware interrupts, critical sections, and context switching overhead at the silicon register level. They design clean task architectures that avoid excessive stack allocations, verify timing using logic analyzers, and produce maintainable code that meets rigid embedded industry standards.
Frequently asked questions
Not sure where to start with FreeRTOS? These answers cover the essentials.
Organizations implement FreeRTOS when transitioning away from bare-metal superloops toward deterministic multitasking. The kernel manages concurrent processes like sensor polling, motor control loops, network communication, and local user interfaces without missing hard deadlines.
Unlike embedded Linux, FreeRTOS requires minimal memory footprints measured in kilobytes, booting instantaneously on low-power microcontrollers. While Zephyr RTOS offers an integrated driver ecosystem, this microkernel excels when teams require minimal architectural overhead and fine-grained control over silicon peripherals.
A solid FreeRTOS background relies on mastery of embedded C or modern C++, deep understanding of microcontroller peripherals like DMA and timers, and proficiency with hardware protocols such as SPI, I2C, CAN bus, and UART. Familiarity with hardware debuggers and oscilloscopes is equally vital.
While standard FreeRTOS is free and open-source under the MIT license, safety-critical projects in German medical or industrial sectors often select SafeRTOS. It provides certified reliability following standards like IEC 61508 or ISO 26262, utilizing an identical design philosophy.
Yes, the modern modular libraries maintain official integrations for MQTT, PKCS #11, and mbed TLS. A specialist working with FreeRTOS configures secure element storage, mutual authentication, and fail-safe over-the-air firmware updates directly to major cloud providers.
Many design, architecture, and simulation tasks proceed entirely remotely. However, teams in Germany typically ship hardware development boards to the specialist, though physical lab presence is occasionally required for custom test benches, climate chamber testing, or EMC certification.
Developing reliable products requires senior-level familiarity with RTOS internals. An expert handling FreeRTOS must accurately calculate task stack allocations, choose proper heap management strategies, and prevent thread synchronization issues such as race conditions and deadlocks.
Review the specialist's experience with board support packages and interrupt latency optimization. Quality FreeRTOS code demonstrates clean separation between ISRs and task space, zero reliance on non-reentrant library calls, and adherence to strict static analysis rules.
The average hourly rate of freelancers in Germany who have used FreeRTOS in their recent projects is 92 €, which corresponds to a daily rate of about 733 € based on an 8-hour working day.
Of the freelancers in Germany who have used FreeRTOS in their recent projects, 86% hold at least a Bachelor's degree, 57% hold at least a Master's degree, and 5% hold a doctorate.
On average, freelancers in Germany who have used FreeRTOS in their recent projects have 18 years of professional experience, with a single engagement typically lasting around 3.3 years.
