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

- Configured and operated the virtualization platform with OLVM and Ansible-based provisioning
- Containerized and redeployed critical services: WordPress, Jenkins, PostgreSQL, MariaDB, Subversion with Apache + AD integration
- Developed Ansible playbooks for automated deployment and configuration management
- Integrated Foreman for repository and security management in the DMZ
- Produced technical documentation in Markdown; organized in Bookstack
- Coordinated with external vendors (e.g. HPE) for hardware installation and setup
- Delivered all contributions documented and reproducible in Markdown

About the technology
What SELinux does
SELinux, short for Security-Enhanced Linux, adds mandatory access control to Linux systems. It limits what users, processes and services can access, even when a process is compromised or a user account is misused. Instead of relying only on traditional Unix permissions, SELinux applies security policy to every relevant interaction.
Policy and enforcement
SELinux policies define allowed actions through contexts, types, domains and rules. Experts configure enforcing, permissive and disabled modes, label filesystems correctly and investigate AVC denial messages. They turn observed application behavior into narrow, maintainable policies rather than weakening protection with broad exceptions.
Ecosystem and tooling
SELinux is closely tied to Red Hat Enterprise Linux, Fedora, CentOS Stream and other Linux distributions. Practical work often includes:
- Managing booleans, file contexts and port labels with semanage and restorecon
- Reviewing audit logs with ausearch, sealert and audit2why
- Writing and packaging custom policy modules with audit2allow and SELinux tooling
- Applying controls to systemd services, Apache, Nginx, databases and container runtimes
Where companies use it
Companies use SELinux to protect web servers, identity services, databases, payment systems and internal platforms. It is valuable where Linux hosts process sensitive data or must contain the impact of a compromised service. In Germany, specialists may support regulated industries and enterprise environments through remote work, on-site operations or a combination of both.
When freelance expertise helps
External expertise is useful during a new Linux rollout, a migration from another mandatory access control approach or an incident involving unexplained denials. A specialist can establish policy baselines, remediate mislabeling, review container isolation and document operational procedures. Common signals include:
- Services fail only when SELinux is enforcing
- Teams use chcon or setenforce as permanent workarounds
- Custom applications lack a tested policy module
- Audits require evidence of least-privilege controls
Signs of strong professionals
Strong SELinux professionals explain why a denial occurs and identify the smallest safe policy change. They understand Linux permissions, systemd, networking, containers, automation and incident response alongside policy language. Look for experience with testing in enforcing mode, policy versioning, rollback plans and clear documentation that operations teams can maintain.
Frequently asked questions
Key details about SELinux, drawn from the questions we get asked most.
SELinux is used to enforce mandatory access control on Linux systems. It restricts processes and users to explicitly permitted actions, helping contain compromised services and reduce unauthorized access to files, ports and system resources.
SELinux uses labels, types and domain policies to control interactions across a Linux system. AppArmor is generally profile-based and associates rules more directly with application paths, so the better choice depends on the distribution, existing skills and required policy model.
SELinux work benefits from strong Linux administration, systemd, networking and audit-log analysis skills. Container security, Kubernetes, Ansible, Bash and knowledge of web servers or databases are also valuable when policies must operate across modern infrastructure.
SELinux expertise should match the risk and scope of the environment rather than a fixed duration. A smaller policy adjustment may need focused troubleshooting, while a production rollout requires policy design, testing, automation, documentation and a controlled migration plan.
SELinux projects can often be handled remotely through secured access, logs, configuration repositories and controlled test environments. On-site work may help with restricted infrastructure, hardware access or incident response, while German or English communication should follow the operating team's needs.
SELinux quality is shown by precise diagnosis, least-privilege policies and safe changes that remain enforceable after deployment. Ask how the specialist handles AVC denials, tests custom modules, manages labels and prevents audit2allow output from creating unnecessary permissions.
SELinux support is valuable when enforcement breaks an application, a new service needs a policy or an audit requires stronger Linux isolation. It is also useful before a migration, container rollout or production hardening effort, when mistakes could interrupt critical services.
SELinux assignments in Germany may involve enterprise Linux, hosted infrastructure, public-sector systems or regulated workloads. Professionals should be comfortable with remote collaboration, clear change records and access controls, while on-site visits may be required for sensitive environments or operational handovers.
