EMPLOYEE FOR WORK PREPARATION
M/F/D
You don’t just see a window – you see every detail.
Every window begins with an idea.
An architect draws a line.
A client has a dream.
A customer wants light.
A joiner waits for the first cut.
Amongst all these people, there is one person who brings everything together.
Perhaps that person is you!
Ideas become windows, and your planning becomes quality!
At OST-Fenster, we don’t produce standard products. Every window, every front door, every sliding element is made to measure.
Why OST?
We have been manufacturing windows and doors made of wood and wood-aluminium for over 50 years.
Not mass-produced – but made to measure.
For people who demand the very highest standards of quality, design and durability. Our customers don’t just invest in windows. They invest in their home. And that’s precisely why we invest in people who are masters of their craft.
Join our team!
- Order processing, design and ordering of materials
- Creating and checking drawings (CAD)
- Clarifying technical details internally
- Preparing order and production documentation
- Contacts and communication with suppliers
- Training as a joiner, woodworking technician, technical draughtsman or a comparable qualification
- Experience in window manufacturing
- Technical understanding
- An enjoyment of planning and organisation
- The ability to work independently
- Team spirit

- The ability to keep track of everything, even on complex projects
- a modern, second-generation family business
- a team that works together rather than just alongside one another
- high-quality projects rather than mass production
- modern software
- short decision-making processes
- opportunities for further training
- a secure job with a future
- appreciation for your work

For homes where families celebrate Christmas. For windows where the first coffee of the morning is enjoyed. And for people who come home every day and say: ‘I feel at home here’.
That’s exactly what you’ll be helping to create!
Not on an assembly line. But with your own hands. With your skill. With your passion.
Because an OST window isn’t just an industrial product. It’s genuine craftsmanship!
