What it means when you work for us

The roots of Fresenius Umwelttechnik GmbH date back to 1848, when Carl Remigius Fresenius founded the Fresenius Chemical Laboratory. Building on this rich history, we responded our own technical solutions for sampling in environmental and contaminated site management as early as 1989 with the development of early to the increasing demands and process gas measurement technology. In 1992, this became the independent Fresenius Umwelttechnik GmbH, which has since successfully developed, produced, and globally distributed innovative measurement systems for emission and immission control, as well as industrial process measurement technology.


From Engineering to Technology – our Mission for the Future

Today, we stand at a turning point: Our strategic goal is to consistently transform ourselves from a classic device manufacturer into a modern high-tech company. We are focusing on smart sensor technology, AI-supported data analysis, cloud-based platform solutions, and pioneering environmental technologies – for a world that should become cleaner, safer, and smarter.


Shape this Transformation with Us!

To shape this ambitious transformation, we are looking for dedicated individuals who want more than just a job – people with ideas, curiosity, and the will to make a difference. Whether in marketing, engineering, or sales: With us, you will not only find a company with history, but above all, a future that you can help shape.

We are looking for the earliest possible start date:

Service Team Leader - Mechatronics & Electronics

Are you technically strong, eager to take on responsibility, and looking for a position that can grow with you?

Then this could be your next career step.

We are not looking for a manager who exclusively organizes and delegates. We are looking for a technically savvy doer with leadership potential who will further develop our technical service together with a small team.

You will work operationally, take responsibility for people, technology, and results – and at the same time get the chance to develop a professional and growing service department from a small team.

Your Mission

Our measuring devices and systems are used for monitoring demanding industrial processes. Accordingly, the requirements for availability, reliability, and technical service are high.

As a hands-on Service Team Leader, you will assume technical and organizational responsibility for our service team.

You don't just coordinate – you can do it yourself.

You analyze technical problems, develop solutions, and support your team, especially where it gets challenging.

At the same time, you think ahead:

How can we make our service faster, more digital, more efficient, and more scalable?

What you will achieve with us: Technology & Service

  • Diagnosis and systematic analysis of technical faults
  • Maintenance, repair, and testing of our electronic and mechatronic measurement systems
  • Commissioning and technical support for devices and systems
  • Handling particularly demanding technical service cases
  • Technical support for our customers
  • Analysis of recurring error patterns
  • Collaboration with development and production for continuous product improvement

Team & Leadership

  • Technical and organizational leadership of an initially small service team
  • Planning, prioritization, and distribution of tasks
  • Support and professional development of your employees
  • Ensuring quality, adherence to deadlines, and customer satisfaction
  • Establishing clear responsibilities and efficient processes
  • Prospective involvement in the selection, onboarding, and development of new team members

Processes & Digitalization

  • Further development of our service processes
  • Establishment of meaningful service and quality key figures
  • Digitalization of documentation and knowledge management
  • Structured use of service and device data
  • Application of suitable AI tools for technical research, documentation, error analysis, and process optimization
  • Development of preventive and data-driven service approaches

Service as a Future Business Area

We do not want to understand service exclusively as a repair function.

Together with you, we want to consider what new service and digital products can be developed from our technical know-how and data.

This may include, for example, digital diagnostic offerings, remote services, maintenance concepts, data-based condition monitoring, or new after-sales services.

You will have the opportunity to actively shape this area.

Your Profile – Technical Competence Meets Leadership Potential

You have completed technical training, for example as a:

  • Mechatronics technician
  • Electronics technician for devices and systems
  • Electronics technician for automation technology
  • or a comparable qualification.

Particularly interesting for us is additional training as a certified technician or master craftsman.

Alternatively, you have a relevant degree, for example in:

  • Electrical Engineering
  • Mechatronics
  • Automation Technology
  • Measurement and Control Technology
  • Process Engineering
  • or a comparable technical field.

The degree alone is not the deciding factor for us.

What is crucial is that you truly understand technology, can systematically solve problems, and are willing to take on responsibility.

What We Expect From You

You bring practical experience in a technical environment and possess sound knowledge in electronics and/or mechatronics.

You work in a structured and independent manner, can quickly grasp technical contexts, and consistently get to the bottom of problems.

Furthermore, we expect:

  • high level of initiative and strong implementation skills
  • pronounced quality awareness
  • organizational talent and clear prioritization
  • readiness to take responsibility and decision-making ability
  • binding and appreciative communication
  • customer orientation and economic thinking
  • willingness to actively participate operationally
  • openness to digitalization and new technologies
  • good German and English language skills

Initial leadership experience is welcome, but not a mandatory prerequisite.

If you are technically strong, possess natural authority, and can inspire people, we will give you the chance to develop into a leadership role.

Leadership for us means: Competence instead of Title

We are not looking for a classic department head.

Your leadership role arises from technical competence, clarity, reliability, and the ability to make decisions.

If your team needs support, you are there.

If a difficult technical decision needs to be made, you take responsibility.

And if processes aren't working, you don't wait for someone else to improve them.

You lead by taking responsibility.

Your Learning Curve

We don't expect you to know everything already.

You will work closely with highly experienced and technically competent leaders and specialists and gain direct access to extensive know-how in gas measurement technology, sensor technology, electronics, and industrial process monitoring.

This knowledge is actively shared.

Thus, this position offers ambitious technicians, master craftsmen, and engineers the opportunity to significantly develop professionally and as a leader within a comparatively short time.

We expect performance – but we also invest in your development.

AI & Digitalization are essential tools for us

We are evolving from a classic device manufacturer to a modern technology company.

Therefore, we expect you to understand new technologies not as a threat, but as a tool.

Professional handling of suitable digital and AI-supported tools should increasingly become second nature to you.

AI can support you, for example, in error analysis, technical research, documentation, knowledge management, evaluation of service data, and process optimization.

The following applies:

AI does not replace technical competence – it makes good technical competence more powerful.

Your Career Path

This position is expressly not intended as a final destination.

We are looking for an individual who wants to grow with our company and our service department.

Level 1 – Service Team Leader

You take over a small team and actively participate operationally.

Your focus:

Understand technology. Ensure quality. Lead team. Improve processes.

Level 2 – Head of Technical Service

With growing business and corresponding personal performance, you will increasingly take responsibility for the entire technical service.

This may include:

  • growing service team
  • personnel development
  • service organization and capacity planning
  • international service activities
  • service key figures and profitability
  • digital service processes
  • new after-sales and service products

Your focus will increasingly shift from operational involvement to leadership, organization, and business development.

Level 3 – Head of Production & Service / Technical Operations

For an exceptionally high-performing individual, a further management function can develop from this in the long term.

Then it's no longer exclusively about service.

Possible responsibilities:

Production | Service | Technical Processes | Quality | Resources | Digitalization | Operational Performance

Thus, the position offers a possible path from a technically strong practitioner to team leadership and up to an operational management position within the company.

What Determines Your Next Step

For us, tenure alone does not determine who gets more responsibility.

The deciding factors are:

Performance. Competence. Readiness to take responsibility. Leadership ability. Results.

Whoever demonstrates that they can successfully develop an area should also get the chance to lead that area.

What we offer you

  • Responsible technical key position
  • Leadership experience with manageable entry
  • Clearly recognizable development perspective
  • Direct influence on technical quality and customer satisfaction
  • High degree of creative freedom
  • Short decision-making paths
  • Direct collaboration with technically experienced decision-makers
  • Intensive professional learning opportunities
  • Modern measurement, diagnostic, and digital tools
  • Further training in technology, digitalization, and leadership
  • Attractive, performance-based compensation
  • Voluntary profit sharing
  • Company supplementary health insurance
  • Modern working environment
  • Free parking and e-charging facilities
  • Regular internal and team events

Why This Position is Special

We are looking for neither a pure technician nor a pure manager.

We are looking for someone who can become both.

Today, you're with your team at the device, solving a challenging technical problem.

Tomorrow, you'll develop the process so that this problem is detected faster or completely avoided.

And in the long term, you might lead the entire department responsible for it.

Technical Competence → Team Leadership → Departmental Responsibility.

We want to pursue this path with the right individual.

Ready for the next step?

If you want to apply your technical skills in a future-oriented company, we look forward to receiving your application (including salary expectations & possible start date, preferably as a PDF) via email.

You don't have to be a finished manager yet.

But you should aspire to become one.
