On the Road and Continuously Learning

Smooth-running tools and technologies are crucial for scientists worldwide, who work on finding breakthrough solutions against cancer, inheritable diseases, and future pandemics. But who ensures these tools work flawlessly, so researchers can focus on their work? Enter the Sartorius service teams, who support life science and biopharma customers around the world – while advancing their own careers.

This article is posted on Sartorius Blog.

At Sartorius, two specialized Services teams work hard to ensure that biopharmaceutical researchers and manufacturers can keep their critical work on track:

"In the bioprocess division, our main objective is to support our customers in the biopharmaceutical and pharmaceutical industries," explains Stephan Theisen, Head of Services in Sartorius’ Bioprocess Solutions. "This means after the team has performed the installation and qualification of the systems, we take care of the product process security during production by minimizing downtimes." His counterpart, Richard Ploner, Head of Services in the Lab Products & Services Division adds: "For our research customers, our team takes care of the entire lab instruments portfolio, which reaches from lab balances, lab water systems and pipettes to highly complex bioanalytical instruments. Our most important objective is to have satisfied customers." 
 

On the Road: Delivering Expert Support and Building Customer Relationships

Fabienne Vogt, Switzerland-based Field Services Engineer, supports customers with on-site expertise and care.

 

Fabienne Vogt, based in Switzerland, is a dedicated Field Services Engineer in the Bioprocess Solutions services team. She supports customers on-site, ensuring their needs are met with expertise and care. Her main responsibilities include performing annual and preventive maintenance, addressing repairs, providing technical assistance, and troubleshooting potential issues on-site. 
“What I enjoy most about my job is being on the road and interacting with customers. I get to see a lot of different companies and learn how they handle their media to produce medicines, and I meet new people continuously.”

Another aspect Fabienne appreciates are the training opportunities in her field: "At Sartorius, you can take part in technical training courses any time and learn more about tools and functions. The variety of our systems is enormous and so is the know-how among colleagues – and all of them are very open to sharing their knowledge."

A Space to Grow: Career Advancement in Services

Working in the Services department – whether as a Field Service Technician, Service Engineer, or Technical Support Engineer – provides a dynamic environment where professionals can thrive and develop their careers. A prime example for this is Jonnie Hannah.

 

It’s nice to know that the work that we’re doing has a good purpose behind it.

Jonnie Hannah, Team Lead Services BioAnalytics

Jonnie's career in engineering took off with an electrical engineering apprenticeship in a pharmaceutical company that combined hands-on work with training and studies. During this time, he gained experience in a manufacturing setting and became well-acquainted with stringent quality and compliance regulations in the pharmaceutical industry. 
 

Advancing through various roles in Services, Jonnie Hannah became a Field Service Engineer and now leads a team of  field service engineers for the BioAnalytics portfolio. 


In 2018, Jonnie took the leap to Sartorius as a Technical Engineer. Over the years, he advanced to Field Service Engineer for the bioanalytics portfolio. In this capacity, he serviced, maintained, repaired, and installed all bioanalytical equipment. “As an engineer, you’re always learning,” Jonnie shares. “I also really enjoy the customer-facing side of the role, communicating with our customers and understanding what they are trying to achieve with the instrument,” Jonnie says. “It’s nice to know that the work that we’re doing has a good purpose behind it.”


In 2024, Jonnie’s journey came full circle when he stepped into the role of Team Lead for the  BioAnalytics services team. Now leading a group of seven field service engineers, Jonnie and his team work on products like the Incucyte, a live cell imaging and analysis system, and the CellCelector, an automated cell imaging and picking system. 
 

Incucyte SX5 instrument

Incucyte®

At the beginning of the research process, the Incucyte live-cell analysis system helps scientists to better understand the mechanism underlying a disease. Sitting directly in an incubator, it tracks and analyzes cell reactions and interactions 24/7, for example how cells grow, move from one location to another, change in size, or shape, or how they react to a drug candidate. With this knowledge, scientists can study the behavior of target molecules in living cells. For the design of coronavirus therapeutics, for example, one target was the spike protein of the SARS-CoV-2 virus.

Once a target molecule is identified, researchers screen large compound libraries to see if one of these can address the target – that means it can bind to the target and has potential therapeutic effect. For this screening, a large number of samples with cells or particles that have been treated with potential drugs need to be analyzed. The iQue®3 helps to identify the most promising ones more quickly with the fastest sample acquisition time in the industry followed by automated analysis.  With this technology, scientists can screen thousands of compounds in hours instead of days.

Octet®

Once a promising lead has been identified, it needs to be further optimized. The Octet® helps measure how well different drugs bind to the target molecule, analyzing binding affinity and kinetics in real-time. These factors are important to study in that they may affect the drug's optimal dosing and efficacy.

CellCelector

In a next step for many biologics or biological products, scientists aim to find and develop a cell line that can be used to manufacture the drug candidate. The CellCelector can screen large numbers of clonal cell lines for their productivity, growth rate, or other characteristics to help identify the most promising candidates for further development. Crucially, it can accurately identify clones that have been generated from a single cell, thus ensuring 100% monoclonality, a requirement for developing cell lines that are the biological factories of certain protein therapeutics.

Every day is different, and my job role is very dynamic. New challenges always present themselves within service.

Jonnie Hannah, Team Lead Services BioAnalytics

Reflecting on his experience, Jonnie concludes: "Sartorius is a fantastic company to work for. The opportunities are endless. Due to the size and the broadness of the company, there are different divisions and departments that you can transition to if you wish to grow your career further. Whether it's progressing into service management, delving deeper into the technical aspects of product development, becoming an expert on specific products, or transitioning into manufacturing and quality roles."
