Interview with Stefanie Müller: Technology, Change, and True Equality Insights on International Women in Engineering Day at TLT-Turbo
Stefanie Müller is Demand Manager at TLT-Turbo – and has been part of our team for over a decade. Her journey has taken her from foundry technology to engineering and now to a strategic interface role connecting sales, engineering, and customers. In this interview for International Women in Engineering Day 2025, she shares her thoughts on motivation, change, equality – and why, for her, implementation often matters more than the concept itself.
Interview with Stefanie Müller
Position: Demand Manager
Location: Zweibrücken
At TLT-Turbo since: Over 10 years
“Technology fascinates me – but it’s only through great collaboration that it becomes truly successful.”
From Model Building to Demand Management – A Career Fueled by Passion
Stefanie, you’ve been with TLT-Turbo for more than 10 years. What originally drew you to technology – and what has kept you motivated ever since?
“Even before my studies, I completed an apprenticeship as a model maker specializing in foundry technology. Learning to work with metal, plastic, and wood from the ground up was incredibly fulfilling.
At the end of my apprenticeship, I became pregnant and had the opportunity to support the office with NC programming and project management. Those experiences inspired me to pursue further studies.

From the beginning, and still today, my greatest motivation is the joy and pride I feel in creating something new – in turning an idea into reality.
In recent years, I’ve also developed a strong interest in interdisciplinary collaboration, both within the company and beyond.
Because no matter how good a concept is – if the implementation fails, the idea won’t succeed.”
From Engineering to Strategy – Embracing Change and New Perspectives
You transitioned from design engineering to demand management. How has your perspective on technology and collaboration changed?
“Change is essential – it gives us the chance to try new things and grow.
The role of Demand Manager gave me exactly that opportunity.
I realized that many challenges I faced as an engineer could be avoided through better communication, cross-departmental collaboration, and smart use of tools.”
Interface Work: A Challenge and Opportunity in One
What do you find most exciting about working at the intersection of engineering, sales, and the customer?
“Many mistakes or misunderstandings happen because people don’t share the same information.
This can be costly, frustrating, and time-consuming. Questioning whether every department really needs its own Excel sheet with similar data – and then working together to find better solutions – is a real challenge.
It takes persuasion to break down old habits. But it’s incredibly rewarding when you start seeing success – smoother projects, less effort, better results.”

Technology Has No Gender – Only Curiosity
What would you say to young women who are curious about engineering but still hesitant?
“My advice: To encourage more women to pursue careers in engineering – or more boys to follow their passions in so-called ‘female jobs’ – we need to remove boundaries.
Society, families, schools, and kindergartens should allow every child the same freedom to explore.
No limits, no taboos. Let kids discover the world in all its diversity.
Personally, I don’t like discussions around equality quotas or initiatives like Girls' or Boys' Day. To me, true equality exists when it’s no longer a topic – when it simply goes without saying.
Everyone should follow their passion. Whether it’s a boy who wants to take over his father’s workshop or become a preschool teacher. Or a girl who dreams of becoming a nurse – or chooses to be a stay-at-home mom.
I chose mechanical engineering, but during school I could’ve just as easily imagined becoming a midwife. Both were valid options – because as a child, I wasn’t limited by expectations.
I was allowed to help with renovations, build my own projects (like a rabbit hutch or “villa”!), experiment freely with cooking and baking at my grandma’s, and babysit. All of those experiences broadened my perspective.”
With colleagues like Stefanie Müller, it becomes clear: technical expertise and bold ideas go hand in hand – and true equality has the greatest impact when it’s lived as a matter of course.
