Embedded Systems Consultant / Architect | Integration and Validation Engineer / Manager at Ingenieurbüro Baig
Led the hardware development and validation of a safety-critical 400 V battery management system (BMS) for the TOGG SUV program; performed system architecture reviews, schematic validations, EMC and reliability tests, and root cause analyses in line with relevant automotive standards (ECE-R10, CISPR25, ISO-26262). Coordinated cross-border EU engineering teams, customer reviews, and technical documentation to deliver a production-ready, validated system.
Architected and integrated 22 state-of-the-art ADAS validation vehicles for BMW ADCAM and LIDAR programs at Magna Electronics; synchronized up to 26 heterogeneous sensors (LIDAR, RADAR, cameras, GNSS/INS) using PTP-based timing architectures. Defined the system architecture, HW/SW interfaces for hardware-in-the-loop (HIL) reprocessing, sensor integration strategies, and data acquisition frameworks. This enabled scalable vehicle-level validation, improved validation efficiency by 25%, and reduced project costs by €1.45 million.
End-to-end validation and integration of automotive radar platforms for a Daimler project at Continental. Developed automated open-loop hardware-in-the-loop (HIL) environments to accurately test target tracking KPIs, field of view limits, and thermal and voltage-related ECU state machines.

Architecture and Programming for Automotive Test Bench Platform at Automotive Supplier
In this project, I was responsible for the design and implementation of a new, modular, and highly scalable test bench platform for an automotive supplier. My focus was on developing a robust system architecture and programming the associated software, with consistent use of UML modeling throughout. This structured approach made it possible to greatly increase the reusability of individual LabVIEW test modules and to significantly reduce development time for follow-up projects. I also integrated modern automotive standards such as CAN FD, LIN, and safety requirements, which made the solution future-proof.

About the technology
PLC basics
A Programmable Logic Controller, or PLC, is the control unit that runs machines, lines, and industrial equipment. It reads sensors, executes logic, and sends commands to drives, valves, motors, and alarms. Companies use it to keep operations stable, safe, and repeatable.
Common systems
PLC work often centers on vendor ecosystems and their engineering tools.
- Siemens S7, TIA Portal, and Step7
- Allen-Bradley and Studio 5000
- Mitsubishi, Omron, Beckhoff, and Schneider Electric
- HMIs, I/O modules, and industrial networks
What specialists deliver
Strong specialists write and maintain control logic, handle commissioning, and adjust sequences during ramp-up. They also support fault finding, alarm handling, interlocks, and communication with SCADA or MES systems. Good work shows up in clear documentation and clean handover.
When companies hire
Companies bring in freelance PLC experts when a line is being built, retrofitted, or stopped by a fault that needs fast diagnosis. They also help when a plant changes product formats, adds sensors, or migrates old logic to a new platform. In Germany, this often involves site work in manufacturing and process industry settings.
Good signals
- Experience with the exact PLC platform in use
- Safe handling of machine start-up and change control
- Strong debugging of I/O, communication, and timing issues
- Clear wiring, test, and handover documentation
- Comfort working with maintenance, production, and electrical teams
Adjacent skills
PLC specialists often need more than ladder logic. Useful nearby skills include industrial networking, safety circuits, motion control, HMI screens, SCADA integration, and reading electrical drawings. For remote collaboration, they should also explain changes clearly and support on-site teams during testing and commissioning.
Frequently asked questions
The facts hiring teams ask for most often when it comes to Programmable Logic Controller.
A Programmable Logic Controller runs the control logic that keeps industrial equipment moving in the right order. It reacts to inputs from sensors and switches, then controls outputs such as motors, valves, alarms, and safety signals. That makes it central to machines, production lines, and process systems.
Bring in a PLC specialist when a project needs fast commissioning, a platform migration, or urgent fault finding. Freelancers are also useful when the internal team knows the machine but lacks time for detailed debugging, documentation, or controls integration. They can step in for a single site visit or a longer change project.
No, but the terms are closely related. PLC is the general term in English, while SPS is the common German term for the same type of control system. Siemens S7 is a widely used PLC family, so people often search for the platform name when they really need PLC expertise.
A strong Programmable Logic Controller expert usually knows the platform your site already uses, not just one language or one brand. In practice, that often means Siemens, Allen-Bradley, Beckhoff, Omron, Mitsubishi, or Schneider Electric tools and their related engineering environments. Exact platform fit matters more than broad claims.
A good PLC professional should also understand industrial networking, HMIs, SCADA, drives, and basic electrical documentation. Safety circuits, sensors, actuators, and motion control are often part of the same scope. The best specialists can work across logic, wiring, and commissioning without losing track of the process.
A Programmable Logic Controller project needs enough experience to match the risk and complexity of the equipment. Small logic changes may only need a specialist who knows the platform well, while plant start-ups or migration work need someone who has handled testing, version control, and rollback planning before. Look for proven project evidence, not vague claims.
Many PLC tasks can start remotely, such as code review, troubleshooting, and planning changes. But commissioning, wiring checks, cabinet inspections, and final sign-off usually need on-site presence. In Germany, hybrid collaboration is common when the machine is local and the specialist can travel for testing phases.
Ask for examples that match your exact environment, not just general control work. A strong Programmable Logic Controller expert can explain how they debug faults, protect safe operation, document changes, and support handover to maintenance. Clear answers about testing and commissioning are a better sign than broad promises.
The average hourly rate of freelancers in Germany who have used Programmable Logic Controller in their recent projects is 95 €, which corresponds to a daily rate of about 762 € based on an 8-hour working day.
Of the freelancers in Germany who have used Programmable Logic Controller in their recent projects, 89% hold at least a Bachelor's degree, 54% hold at least a Master's degree, and 10% hold a doctorate.
On average, freelancers in Germany who have used Programmable Logic Controller in their recent projects have 23 years of professional experience, with a single engagement typically lasting around 3.9 years.
