Revenue of PLN 2.2BN in 2025, no debts, since 2006 on the market – numbers prove our strength & credibility. 

At Sii we have a lot of knowledge sharing initiatives – our workers can join  technology Communities, participate in a mentoring program or benefit from in-house trainings, blog and e-learning platforms. 

We are a key partner for many prestigious global companies from different sectors i.a: BNP Paribas, KUKA, ING or Bombardier with whom we have contracts that guarantee continuity of employment for our workers.  

Programs dedicated to reward workers who have referred the largest number of friends to work or who have passed on valuable sales leads. The best ones receive special prizes and bonuses – up to SEK 50 000!  

 The recommendation contest is also for people outside the company – find out more!

A development program consisting of a collaboration between an experienced employee – Mentor – and a Mentee, i.e. a person who wants to expand his or her knowledge. In addition to its educational value, the program fosters integration, collaboration and develops soft skills. 

Our values are Sii DNA. They reflect who we are and guide us in our daily decisions. When joining our company, it is worth to know them.

We do our best to create an inclusive and empowering workplace where everyone has an equal opportunity to develop and reach their best. Such an approach is rooted in our mission, strategic goals and 14 Sii’s values. 

Sii has the following programs: supporting foreigners, Power Umberella – support and understanding for LGBTQ+ employees, Power Woman, Power Mum, Power Kids. 

Fun is one of our 5 goals! Our employees are invited to events to share knowledge, important moments for company or branch office, integration, fun and our passions. 

We allocate PLN 1M annually for the development of passions and hobbies through our Passion Sponsorship & Volunteers programs. Thanks to this funding, 25% of our Power People pursue their dreams each year – such as climbing Mont Blanc, running races in the most remote corners of the world, or sending a balloon into the stratosphere.

No matter our title, we address each other by first names. Transparency and dialogue are important for us, that’s why we periodically organize local CEO meetups, online CEO live sessions and departmental Inspiration Days. During them everyone has the opportunity to meet with people managing the company, ask questions, report problems and discuss troubling issues.

Sii shares its profit with employees to thank everyone for a great year and results. We know that without the huge commitment of Power People, the company’s success would not be possible. From 2022, over PLN 76 M has already been allocated for this aim. 

Gifts to celebrate important moments with our workers – weddings, new babies in the family, work anniversaries and others. The first day at Sii also begins with a welcome pack of useful tools and accessories.
