Why is it
worth joining TTMS?

1

Flexible working hours

Not everyone is comfortable operating a company during the standard 9 a.m. – 5 p.m. hours. We have been successfully running projects for many years despite diversified work patterns.

2

Possibility of remote work

At TTMS, desk-to-desk work is what drives us, but we understand if someone prefers a remote or hybrid model. We are equipped with all the necessary tools to perform either at home or in the office.

3

Great, non-corporate atmosphere

Professionalism, attention to the quality of work and a friendly, informal atmosphere are not mutually exclusive. A flat structure and natural, friendly relationships create the basis for creativity and innovation.

4

Interesting, international projects

We create solutions for medium and large companies, we are present in Poland, Malaysia, Denmark, the UK, Switzerland, and India – the effects of your work will travel around the world. In TTMS you have an influence on the company’s success.

5

Together towards climate neutrality

We select subcontractors to minimize the carbon footprint, organize bush plantings, save peat bogs – all to achieve climate neutrality in 2025. We are glad that we are attracting more and more people who also care about sustainable development and environmental protection.

Friendly offices

Our offices are modern spaces that inspire employees and are environmentally friendly. Białystok is the kingdom of Marvel superheroes, Krakow is a soothing tropical forest, Wrocław is an art gallery, and the Lublin branch is a rock “hall of fame”.
