Our brand Deutsche Telekom IT Solutions Slovakia entered the life of Košice region in 2006 under the name of T-Systems Slovakia and ever since has been inextricably linked with the region when became one of the founding members of Košice IT Valley. We have managed to grow from scratch to the second largest employer in the eastern part of the country with more than 3900 employees. Our goal is to proactively find new ways to improve and continuously transform into the type of company providing innovative information and communication technology services.

Deutsche Telekom offers the position of a Senior Generative AI Expert in the department Product Innovation & Customer Experience (PIC) of the board area Technology & Innovation.

We are deeply convinced Generative AI has tremendous transformative potential across many areas of our business – both in customer-facing and internal ones. We will help tackle this huge opportunity with a strong Generative AI center of expertise within our board area Technology and Innovation, driving change across the company in tight cooperation with our business units. The objective of this center of expertise is not only to deeply understand and work with leading-edge 3rd party Generative AI technologies to build new products with superior customer experience and enhance internal efficiency. We will also build our own strong foothold and technology in this space, i.a. by leveraging Open Source developments.

The candidate will be part of a strong AI expert team that is the key driver of this development and will help DT meet its objective of becoming a leader in our industry and beyond in leveraging the power of Generative AI – in an ethical and safe way.

WHAT WILL YOU DO?

• You will be a part of the Generative AI center of expertise with the mission of exploring leading-edge Generative AI technologies, to build new products offering superior customer experience and driving internal efficiency. Our goal is to become a leader in our industry and beyond in leveraging the power of Generative AI.
• You bring extensive expertise in Generative AI technologies of 4+ years and an even longer track record in data science, with significant hands-on experience in developing and orchestrating Generative AI models.
• You have significant experience and understanding of large language / transformer models, cloud-based development, as well as a strong attitude of acting fast and being results-driven.
• You have successfully guided more junior experts in developing Generative AI-based solutions and look forward to combining such guidance with own hands-on work on AI models/solutions at Deutsche Telekom.
• You enjoy working together with an international team of senior experts in the field of Generative AI, mobile working flexibility, as well plenty of opportunities for learning and exchanges at both industry and academic events.

YOU WILL SUCCEED IF YOU :

• Are comprehensive and deep expert knowledge and 4+ years of experience in Generative AI technologies and 7+ years of experience in data science, with significant and extended hands-on experience in developing Generative AI models and potentially supportive/orchestrating technologies of the latter.
• Have ideally extensive experience in building scaling products based on Generative AI technologies.
• Have solid experience in software development, Open Source programming languages.
• Have strong knowledge of cloud technologies like AWS, Azure etc.
• Have experience in managing stakeholder expectations by being highly flexible as well as driving proactive and reactive communication. Being able and motivated to facilitate difficult discussions within the team or with diverse senior stakeholders.
• Have extensive and long-term experience in multi-cultural environments.
• Have excellent communication skills in leading AI technology/strategy discussions in development teams and in meetings with senior management. Should be able to explain complex topics in “crisp simple” language to top management.
• Have strong community engagement in Open Source is highly appreciated.
• Strong track record working in virtual settings across globally distributed teams, strong social and interpersonal/intercultural skills.

• Are able to act quickly, set new technical directions, empower the team to make decisions and aid the team with smart but fast decisions and engage in focused experimentation.
• Results Driven - confident, thrives on hard work and consistent challenge, and is quick on his/her feet. Monitors quantitative progress measures and acts quickly on deviations from plan.
• Are creative thinking to push the envelope of Generative AI model optimization and products (e.g. novel architectures, loss functions, or training techniques).

• Have ability and drive to balance AI and product development with ethical considerations (e.g. understanding potential biases, fairness issues, privacy concerns, and societal impacts).

• Speak English fluently on C1 level 
• Have technology education: Ideally mathematical, natural science, and/or engineering university degree; PhD in machine learning or similar highly welcome.
