Enrique G.
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
PLC Basics
Programmable Logic Controller, or PLC, is the control layer behind many machines and production systems. It reads inputs, drives outputs, and runs the logic that keeps equipment moving in a safe sequence. Companies use it for discrete control, interlocks, alarms, and reliable real-time operation.
Where It Fits
PLC work shows up in packaging lines, conveyor systems, process skids, building automation, and factory utilities. In Hamburg, it is also relevant for logistics, food processing, port-related systems, and industrial plants that need stable on-site control. Strong specialists understand how the controller fits into the wider machine and SCADA setup.
Typical Tasks
- Write and maintain control logic
- Map sensors, actuators, and safety signals
- Integrate HMI, SCADA, and drives
- Support startup, commissioning, and troubleshooting
- Document tags, alarms, and signal lists
These tasks often span full project lifecycles, from panel test to handover. Experts must keep sequences clear and failure modes easy to diagnose.
Ecosystem Skills
PLC specialists often work with Siemens S7, TIA Portal, Allen-Bradley, Studio 5000, CODESYS, Modbus, PROFINET, and EtherNet/IP. They should read electrical drawings, understand PID control, and collaborate with electricians, mechanical teams, and safety specialists. Good code is only part of the job.
When to Bring In Help
- A new machine needs control logic from scratch
- An old line must be migrated or cleaned up
- Commissioning is blocked by faults or sequence issues
- A site needs extra capacity for a shutdown or retrofit
Freelance PLC expertise is useful when deadlines are tight or the internal team is focused on operations. Remote support can cover software review, but on-site work is often needed for cabinet checks and commissioning.
What Good Looks Like
A strong PLC professional writes logic that is readable, testable, and safe to maintain. They separate machine states well, handle alarms cleanly, and leave clear comments and as-built documentation. They also know how to work with hardware, not just software, which matters when the system is live.
Frequently asked questions
Curious about Programmable Logic Controller? Here are the answers that come up again and again.
A Programmable Logic Controller runs the control logic for machines and plant equipment. It reads inputs from sensors, decides what should happen next, and drives outputs such as motors, valves, or alarms. That makes it the core of many automation systems.
No. A PLC is the controller that executes real-time logic, while industrial automation software may also include SCADA, HMI, engineering tools, and data layers. Companies often need both, but they solve different parts of the system.
Common PLC environments include Siemens S7 with TIA Portal, Allen-Bradley with Studio 5000, and CODESYS-based systems. Many projects also depend on fieldbus and network tools such as PROFINET, EtherNet/IP, and Modbus. A good specialist should be comfortable across the stack that matches the site.
A strong Programmable Logic Controller specialist usually understands electrical schematics, I/O mapping, safety circuits, HMI logic, and basic motion or drive control. On many projects, documentation and commissioning discipline matter as much as coding. Communication with maintenance and production teams is also important.
It depends on the scope, but even a small change can affect the whole machine sequence. For new builds, retrofits, or migration work, companies usually want someone who has already handled the same type of control system, hardware family, and commissioning phase. For troubleshooting, practical plant experience matters most.
Both, depending on the task. PLC logic review, documentation, and some debugging can be done remotely if secure access is available, but panel checks, wiring faults, sensor tests, and live commissioning usually need on-site work. In Hamburg, many projects combine both to keep downtime short.
Look for clear logic structure, solid comments, and evidence of commissioning work, not just programming claims. A good PLC professional can explain how alarms, interlocks, and recovery states are handled, and can show how they test changes before a plant goes live. They should also document what they changed.
A Programmable Logic Controller is usually chosen for machine control and fast discrete logic. PAC systems overlap with PLCs and may add more data handling, while DCS is more common in continuous process plants. The right choice depends on the equipment, the response time needed, and how the site is organized.
