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
What HMI does
A Human-Machine Interface, commonly called HMI, connects people with machines, equipment, and industrial processes. It presents operating data through screens, alarms, trends, controls, and status views. An effective HMI helps operators understand conditions quickly and act safely without exposing unnecessary system complexity.
Industrial applications
HMI solutions run production lines, packaging equipment, building systems, water treatment plants, energy infrastructure, and process facilities. They can support a single machine or provide a consistent interface across a larger automation environment.
- Monitor machine states, values, and production sequences
- Display alarms, events, trends, and maintenance information
- Control recipes, setpoints, modes, and operator permissions
- Connect field devices with PLC, SCADA, and MES systems
Platforms and tooling
The ecosystem includes Siemens WinCC, Rockwell FactoryTalk View, Schneider Electric interfaces, AVEVA solutions, and Inductive Automation Ignition. Specialists may also work with TIA Portal, OPC UA, Modbus, industrial Ethernet, SQL databases, and historian systems. The right stack depends on the control hardware, plant standards, compliance needs, and required integration depth.
When companies need specialists
Companies often bring in freelance HMI experts during a new line launch, control-system migration, plant expansion, or modernization project. They may need help replacing legacy screens, standardizing navigation, connecting new PLCs, or improving alarm handling. In Germany, collaboration may combine remote configuration with on-site commissioning at a plant or production facility.
- A legacy HMI must be migrated without disrupting operations
- Operators struggle to interpret alarms or process states
- A new PLC, robot, sensor, or MES connection is required
- Several sites need a shared visualization standard
Skills that matter
Strong professionals understand both automation logic and human factors. They translate process requirements into clear screen structures, reusable faceplates, sensible alarm priorities, and role-based access. They can test communication faults, document tag mappings, manage version changes, and validate the interface with operators rather than relying on visual polish alone.
How quality is judged
A dependable HMI is readable under pressure, consistent across screens, and resilient when devices or networks fail. Good specialists define useful alarms, prevent unsafe actions, protect critical controls, and make diagnostics easy to follow. They also leave maintainable project files, naming conventions, documentation, and training materials so plant teams can support the system after handover.
Frequently asked questions
Need clarity? These are the questions we hear most often about Human-Machine Interface.
A Human-Machine Interface gives operators a visual way to monitor and control machines or industrial processes. It shows values, statuses, alarms, trends, recipes, and controls while exchanging data with PLCs, drives, sensors, and supervisory systems.
An HMI usually focuses on operating and visualizing a machine, cell, or local process. SCADA generally covers supervisory monitoring across wider areas, sites, or systems, although modern products can overlap and combine both functions.
A strong Human-Machine Interface specialist may work with Siemens WinCC, Rockwell FactoryTalk View, AVEVA, Ignition, or Schneider Electric tooling. Useful adjacent skills include PLC programming, TIA Portal, OPC UA, Modbus, industrial Ethernet, SQL, MES integration, and alarm management.
For a Human-Machine Interface project, look for experience with a comparable plant process, control platform, and commissioning context. A specialist who has delivered operator screens, tested failure states, documented tag structures, and worked with production staff can usually assess the project realistically.
Much of an HMI project can be handled remotely, including screen design, configuration, simulation, documentation, and software testing. Site access is often useful for hardware checks, network troubleshooting, operator workshops, and final commissioning, particularly in German industrial facilities.
Ask an HMI specialist to explain how they structure alarms, navigation, permissions, tag naming, and recovery from communication loss. Review interface examples, test plans, documentation, and their ability to connect design decisions with operator safety and process requirements.
An HMI professional benefits from knowledge of PLCs, industrial networks, motion control, robotics, databases, cybersecurity, and manufacturing execution systems. Familiarity with usability and human factors is also important because a technically correct screen can still slow down decisions.
A Human-Machine Interface freelancer is useful when a company needs focused expertise for a migration, retrofit, new production line, or short commissioning phase. Freelance specialists can also provide an independent review of an existing interface and a practical plan for improving alarms, consistency, and maintainability.
The average hourly rate of freelancers in Germany who have used Human-Machine Interface in their recent projects is 93 €, which corresponds to a daily rate of about 742 € based on an 8-hour working day.
Of the freelancers in Germany who have used Human-Machine Interface in their recent projects, 88% hold at least a Bachelor's degree, 54% hold at least a Master's degree, and 5% hold a doctorate.
