Employee testimonials
Bogomil Tabakov
Software Engineer
"At A1 I have the opportunity to work on many different IT solutions, both for internal developments and for the company's business customers or partners. The huge variety of projects and the technologies used in them enrich my professional experience. Most of all, however, I enjoy the team - there is no colleague who will refuse help when needed, and it is very nice to have leaders who are an active part of the development process."
Ivan Vasilev
Software Engineer
"The way of working and the environment at A1 made a good impression on me during my internship, so I accepted to become a permanent part of the company. There are a lot of interesting projects in my job and using a variety of new technologies, but I enjoy doing everything mostly because of the people in the team. The users of our software are often different departments within the company, and this can really help a software developer gain more experience in a variety of different areas of the business."
Pancho Radev
Senior Software Solutions Architect, Information Technology and Digital Transformation at A1
What attracted me, and continues to do so, is that A1 is a leader in the telecommunications and information services market, and continues to maintain and develop its leading position, increasingly becoming an IT company.
My job title is Software Solutions Architect - this means that I deal with solutions that are yet to be implemented in the company. My job is to design how they will need to be developed for our needs, how they will integrate with our existing systems.
Tsvetomil Yordanov
Manager of the Operational Software Development Team at A1
The dynamics with which you work, does not allow at any time to be boring and monotonous, which in my opinion is very important for a pleasant working day. After years of working in a big company like A1, I realized that what I was looking for in the beginning is indeed what I like - it brings me satisfaction and I am confident that I made the right choice.
Vanya Danova
Senior Specialist, IT Project Analysis and Coordination, IT and Digital Transformation, A1
A1 is a great company and offers many practical and useful digital solutions that I am starting to use while we are developing them, but the things I value most are the good relationships within the team and with management, and the endless opportunities for learning and development. My professional development here is all about working and interacting with great professionals who show me the way and set an example. Each project brings different value.
