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

About the technology
Secure Unix foundation
OpenBSD is a security-focused, free Unix-like operating system maintained by the OpenBSD project. It is known for secure defaults, careful code review, integrated cryptography and a clear base system. Companies use it for internet-facing services where predictable behavior and a small attack surface matter.
Network services
OpenBSD supports firewalls, routers, VPN gateways, DNS services, mail systems, bastion hosts and authoritative infrastructure. Its PF packet filter, relayd load balancer and OpenSSH ecosystem help teams build controlled paths between users, applications and external networks. Professionals also deliver hardened hosting environments and dependable edge services.
Tools and ecosystem
The system includes a coherent base environment and the pkg_add package manager for additional software. Common work involves PF, OpenSSH, LibreSSL, httpd, relayd, OpenSMTPD, Unbound, bgpd and virtualization with vmm. Specialists may also use Ansible, monitoring tools, shell scripting, Git and network automation around OpenBSD deployments.
When expertise matters
- Replacing an aging firewall or VPN gateway
- Hardening a public-facing Unix service
- Designing segmented network infrastructure
- Migrating from Linux, FreeBSD or proprietary appliances
- Preparing repeatable deployment and recovery procedures
Freelance expertise is useful when internal teams need focused security work, a careful migration or operational coverage without committing to a permanent role. In Germany, OpenBSD may support hosting, telecommunications, research and security-sensitive infrastructure. Remote delivery works well when access, documentation and change controls are ready; on-site work can help with hardware and network handovers.
Skills to look for
Strong professionals understand Unix internals, TCP/IP, routing, DNS, TLS, SSH and firewall policy. They can read system logs, trace traffic, automate configuration and explain the effect of each security decision. Experience with high availability, backups, observability and incident response adds value when OpenBSD carries critical network services.
A sound specialist also knows where the base system ends and external packages begin. They test upgrades, document PF rules, restrict privileges and keep recovery paths practical. Clear communication matters because a secure configuration must remain understandable to the team that operates it.
Evaluating delivery quality
Ask candidates to describe a comparable OpenBSD deployment, its threat model and the reasoning behind its network rules. Review how they handle patching, key management, secrets, logging, rollback and failure testing. A useful technical assessment can cover PF state handling, routing, service isolation and a controlled change to a staging host.
Quality is visible in concise documentation, reproducible configuration and evidence that the professional tested both normal traffic and denied traffic. The right expert balances OpenBSD’s security principles with the existing environment instead of forcing an unsuitable design.
Frequently asked questions
What clients ask us most about OpenBSD — answered in short.
OpenBSD is commonly used for firewalls, VPN gateways, routers, bastion hosts, DNS services and other security-sensitive network roles. Its secure defaults and integrated tools also suit hardened web, mail and infrastructure services.
OpenBSD places unusual emphasis on secure defaults, code auditing and a coherent base system. Linux often offers broader hardware and application support, while FreeBSD is frequently chosen for its networking, storage and jail capabilities; the right choice depends on workload, team skills and operational constraints.
A strong OpenBSD specialist usually brings Unix administration, TCP/IP networking, routing, DNS, TLS, SSH and firewall design. PF, shell scripting, Git, configuration management, monitoring and incident response are also valuable for production work.
The required depth depends on the risk and scope of the work. OpenBSD installations for a small service may need focused system and network skills, while a firewall migration or high-availability gateway requires strong experience with PF, routing, testing, recovery and change control.
Yes, OpenBSD work is often suitable for remote collaboration when secure access, diagrams, inventories and an agreed change process are available. On-site support can still be useful for physical firewall replacements, cabling, console access or a network handover in Germany.
Companies often bring in an OpenBSD freelancer for a new firewall, VPN, routing design, hardened service, migration or security review. External expertise is especially useful when the internal team needs a focused assessment or wants to reduce risk during a sensitive change.
A high-quality OpenBSD professional explains the threat model, keeps PF rules understandable and tests both allowed and denied traffic. They document upgrades, backups, secrets, monitoring and rollback rather than treating a working configuration as the finished result.
OpenBSD rewards careful reading of documentation and disciplined operational habits. Freelancers should understand the base system, package management, privilege separation, release upgrades and tools such as PF, relayd, OpenSSH and Unbound, while communicating clearly with the team responsible for production.
