Last position:
Security Architect at Capgemini
I implemented a Zero-Trust architecture for robust, military-grade maritime container mini data centers based on VMware & Tanzu to support containerized GIS workloads for ground forces. The main focus was on securing communications, workload protection, and data access in contested electronic battle environments affected by jamming, interception, signal manipulation, and constantly changing operational conditions. I designed and architected use cases so that every element of workload, identity, and system could continue to operate independently and securely even in degraded or disrupted scenarios. In parallel, I defined the enterprise and solution security architecture with LeanIX, Bizzdesign, and HOPEX as enterprise architecture, repository, and governance platforms to maintain architecture inventory, relationships, traceability, target pictures, and security governance in complex environments. For the architectural designs, I used Sparx Enterprise Architect to describe formal architecture views, interfaces, trust boundaries, and system architecture in both IT and OT environments. IriusRisk was used for threat modeling of the solution to identify architecture-driven risks, derive security requirements, and detect countermeasures and design gaps directly from the solution models. Risk and compliance management was supported with Archer. Architecture decisions, control gaps, and operational risks were translated into controlled governance and auditable compliance measures. For documentation, collaboration, and visual design, I used Confluence to maintain Architecture Decision Records, Security Blueprints, and workflows. I used Lucidchart and draw.io to create design artifacts tailored to stakeholders. I also defined OT security concepts with support from electrical and mechanical engineers in the areas of oil, vehicle onboard systems, rail, power plants, pharma, gas turbines, and nuclear technology. I created the end-to-end OT security strategy, starting with global policy, developed into standards and procedures, and finally aligned with Bell-LaPadula, Purdue Model, SABSA, TOGAF ADM, CENELEC 50701, IEC 62443, and NIST standards. In addition, I worked with engineering team leads to identify critical KBP assets and place them under protective measures that segmented SCADA, PLC, and HMI assets. I drove collaboration between Security, IT, and OT teams to create standardized workflows and use cases for the OT security solution catalog, while integrating Defense-in-Depth and Zero-Trust principles into operational environments. A key part of my work was integrating multidisciplinary engineering, security, and operations stakeholders into a unified security blueprinting strategy and ensuring that architecture, threat modeling, governance, and documentation were technically strong and operationally practical.

About the technology
Control systems
A Programmable Logic Controller, commonly called a PLC, is an industrial computer built to monitor inputs, execute control logic and operate machinery through outputs. It runs reliably in demanding environments, from production lines and conveyor systems to water treatment, energy and building automation. Unlike general-purpose software, PLC programs are designed for predictable, continuous operation and straightforward fault diagnosis.
Automation platforms
PLC specialists work across vendor ecosystems such as Siemens SIMATIC, TIA Portal, Rockwell Automation Studio 5000, Beckhoff TwinCAT, Schneider Electric and Mitsubishi. Their work can include ladder logic, function block diagrams, structured text, safety control and motion applications. Strong knowledge of industrial networks such as PROFINET, EtherNet/IP, Modbus TCP and OPC UA helps connect controllers with sensors, drives, robots and higher-level systems.
Typical deliverables
- Control logic for machines, cells and complete production lines
- HMI screens, alarms, recipes and operator workflows
- Commissioning, testing and troubleshooting at the plant
- PLC migrations, machine upgrades and software documentation
- Interfaces to SCADA, MES, robots, drives and safety equipment
These deliverables must fit the electrical design, mechanical sequence and operating requirements of the plant. Specialists often translate process descriptions into clear sequences, interlocks and recovery behavior before writing and testing the program.
When to bring expertise
Companies bring in freelance PLC expertise when a new machine needs commissioning, an existing controller requires a migration, or internal capacity is limited during a plant upgrade. Hamburg companies may need a specialist who can work with local production, logistics, maritime or process-industry environments while coordinating remotely with teams elsewhere. On-site access is often important for commissioning, but preparation, simulation, documentation and code reviews can happen remotely.
Safety and quality
A capable professional understands more than programming syntax. They read electrical drawings, define safe states, configure drives and field devices, use version control, and test sequences against real operating conditions. They document tags, alarms, backups and changes so another specialist can maintain the system. For safety-related work, knowledge of the applicable machine-safety process and certified safety components is essential.
Selecting a specialist
Look for evidence of comparable machines, controller families and commissioning work rather than a generic software profile. Ask how the specialist handles downtime, fault finding, backups, change control and handover to the plant team. A strong expert explains trade-offs between PLC platforms, separates standard and safety logic, and leaves behind tested code, usable documentation and a clear recovery plan.
Frequently asked questions
Curious about Programmable Logic Controller? Here are the answers that come up again and again.
A Programmable Logic Controller controls machines and industrial processes by reading sensors, evaluating logic and switching outputs. PLC systems operate conveyor lines, packaging equipment, robots, pumps, HVAC systems and process plants with predictable timing and robust diagnostics.
A PLC is built for reliable industrial control, straightforward maintenance and long operating cycles. Industrial PCs suit data-heavy applications and complex interfaces, while microcontrollers fit embedded products and compact devices; the right choice depends on timing, environment, safety, maintainability and integration needs.
A strong Programmable Logic Controller specialist may work with Siemens TIA Portal and SIMATIC, Rockwell Studio 5000, Beckhoff TwinCAT or another vendor environment. Useful adjacent skills include HMI and SCADA configuration, industrial networking, electrical drawings, variable-frequency drives, robotics, OPC UA, MES integration and safety systems.
The required level depends on scope and risk, not on the technology name alone. A small logic change may need a focused specialist, while a new machine, migration or safety-critical production line calls for someone who has handled design, simulation, commissioning, fault recovery and handover in comparable settings.
PLC work can often begin remotely through requirements analysis, code preparation, simulation, documentation and reviews. On-site access is usually needed for wiring checks, I/O validation, commissioning and troubleshooting; in Hamburg, teams should clarify plant access, security procedures and the language used by operators and maintenance staff.
Programmable Logic Controller projects frequently use Siemens SIMATIC, Rockwell Automation, Beckhoff, Schneider Electric and Mitsubishi systems. The best specialist is not defined by one brand alone, but by practical knowledge of the installed platform, its programming tools, connected devices and the plant's maintenance standards.
Ask for examples of comparable machines or processes and discuss how the specialist approaches sequencing, alarms, interlocks, backups and testing. A reliable PLC professional communicates clearly, documents assumptions, uses disciplined change control and can explain how the system behaves during faults and recovery.
Define the controller and software versions, machine scope, available drawings, required interfaces, safety responsibilities, access arrangements and acceptance tests. A Programmable Logic Controller specialist also needs to know whether the work covers only programming or includes electrical checks, HMI changes, commissioning, operator training and documentation.
