Enrique Gallardo
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
HMI work
Human-Machine Interface, often shortened to HMI, is the layer people use to operate machines and industrial systems. It covers control screens, status views, alarms, trends, and the logic that keeps interaction clear. Strong HMI work reduces errors and helps operators react fast.
Where it is used
- Machine control panels and touchscreen terminals
- SCADA and plant monitoring screens
- Production lines, packaging systems, and process plants
- Alarm handling, trend views, and recipe screens
- Remote access dashboards for service teams
In Germany, HMI is common in manufacturing, automotive supply chains, utilities, and factory automation. Companies bring in specialists when a new line goes live, an older interface feels slow, or operators need a cleaner workflow.
Typical toolchain
HMI specialists usually work close to PLC and SCADA environments, and they often connect interface logic with tags, signals, and alarms. Depending on the stack, they may use WinCC, Ignition, FactoryTalk View, Schneider Electric software, or similar systems. Good work also includes naming, navigation, and consistency across screens.
What strong specialists do
A strong HMI professional turns process logic into screens people can trust. That means clear status messages, simple navigation, safe control paths, and layouts that work on the shop floor. They also test with real operators, because an interface that looks good in a demo can still fail in daily use.
When companies need help
- A new machine or line needs an interface from scratch
- Existing screens are confusing or slow to use
- Alarm handling creates delays or missed actions
- Different sites need a shared HMI standard
- A release needs short-term support near commissioning
Freelance support is useful when deadlines are tight or internal teams are focused on hardware and automation tasks. In Germany, many projects also need clear communication in English and, when required, German for plant-side coordination.
Choosing the right fit
Look for specialists who can explain their screen logic, not just name a tool. Ask for examples of HMI projects, operator feedback, alarm design, and how they handle edge cases. The best professionals think about safety, clarity, and maintainability, not only visual layout.
Frequently asked questions
Need clarity? These are the questions we hear most often about Human-Machine Interface.
A strong Human-Machine Interface specialist builds the screens people use to run machines and monitor processes. That usually includes navigation, alarms, trends, status views, and control actions that match the way operators work. The goal is simple: fewer errors and faster decisions on the shop floor.
No. HMI is the operator-facing layer, while SCADA is broader and often covers supervision, data collection, and plant-wide monitoring. In many projects they work together, but the interface itself is only one part of the stack.
A Human-Machine Interface project often sits next to PLC and SCADA tools. Common names include Siemens WinCC, Ignition, and FactoryTalk View, plus the automation environment that drives the machine data. A good specialist can work across the interface and the signal logic behind it.
A strong HMI freelancer usually understands PLC communication, alarm handling, screen architecture, and industrial UX. They should also be comfortable with testing, commissioning support, and basic process knowledge. If the project is in Germany, clear communication with plant teams is often part of the job.
The more specific your machine, process, and operator needs, the better the fit for a Human-Machine Interface assignment. A good specialist can still help when the scope is incomplete, but they need to know the equipment, tags, alarms, and target users. Screen goals and constraints should be clear early.
Bring in HMI expertise when you need speed, a fresh review, or support during commissioning. Freelancers are also useful when internal automation teams are busy with PLC changes, hardware work, or several sites at once. For Germany-based projects, remote work is often fine for design and review, with on-site time for testing.
Ask to see how the Human-Machine Interface was structured, not just how it looked. Good work shows clear naming, consistent navigation, sensible alarm priorities, and layouts that reduce operator effort. References from real production or machine environments matter more than polished mockups.
Most HMI design and review work can start remotely if the specialist has the process details and access to the control environment. On-site time becomes important for commissioning, operator feedback, and testing with real equipment. In Germany, many teams use a mix of both to keep delivery moving.
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 745 € 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.
On average, freelancers in Germany who have used Human-Machine Interface in their recent projects have 20 years of professional experience, with a single engagement typically lasting around 3.4 years.
The most common languages among freelancers in Germany who have used Human-Machine Interface in their recent projects are German (100%), English (99%), and French (19%).
