Description

Company Description Present in the market under the Deutsche Telekom IT Solutions brand name, IT-Services Hungary (ITSH) is a subsidiary of the Deutsche Telekom Group and is the largest ICT employer in Hungary. Established in 2006, the company provides a wide portfolio of IT and telecommunications services with more than 5000 employees. ITSH was awarded with the Best in Educational Cooperation prize by HIPA in 2019, acknowledged as one of the most attractive workplaces by PwC Hungary’s independent survey and rewarded with the title of the Most Ethical Multinational Company in 2019. The company continuously develops its four sites in Budapest, Debrecen, Pécs and Szeged and is looking for skilled IT professionals to join its team. Job Description We are seeking an innovative and skilled AI Developer to design, develop, and deploy autonomous AI agents capable of proactive decision-making, goal-directed behavior, and contextual adaptability. This role requires a deep understanding of AI planning, reasoning, and interaction mechanisms, with experience in building modular, agent-based systems for real-world tasks across domains such as enterprise automation, research assistance, and interactive applications. Key Responsibilities: Design and implement intelligent, autonomous software agents using LLMs and symbolic or hybrid architectures. Develop multi-agent systems that can collaborate, negotiate, and coordinate on complex workflows. Integrate APIs, tools, and services to enable tool-using capabilities in AI agents (e.g., browsing, databases, command-line tools). Implement memory, planning, and goal-management systems within agentic frameworks. Fine-tune or prompt-engineer large language models (e.g., GPT) to support agent behavior. Build environments for agent simulation, testing, and evaluation (e.g., ReAct, AutoGPT-style frameworks). Collaborate with cross-functional teams to deploy agents into production systems. Monitor and optimize performance, safety, alignment, and interpretability of agentic behaviors. Stay up-to-date with research trends in agent-based AI, reinforcement learning, and cognitive architectures. Qualifications Bachelor’s or Master’s degree in Computer Science, Artificial Intelligence, or a related field. 4+ years of experience in AI/ML development, with agent-based or LLM-integrated systems. Proficiency in Python and relevant frameworks. Strong understanding of LLM APIs, prompt engineering, and embedding models. Experience with tools like vector databases, graph stores, and memory architectures. Familiarity with reinforcement learning, cognitive architectures, or planning systems is a plus.
