About Valka

Valka, a visionary spin-off from the Realms Group (the parent company of Oddin.gg), is on a mission to revolutionize the way people create and experience digital content. Our team believes that content shouldn’t just be consumed; it should be co-created in real time, blurring the lines between imagination and reality. By harnessing the power of cutting-edge AI, we aim to build an interactive human-digital platform where virtual characters respond dynamically to each user’s voice, text, gestures, and more.

This is your chance to join a diverse group of innovators who are driven to redefine what’s possible in generative content. Together, we’re changing the paradigm from passive viewing to active participation, unlocking new creative frontiers across gaming, entertainment, education, and beyond.
About the Role

We are looking for an experienced LLM Engineer to help us build intelligent, automated systems that enhance both internal workflows and customer-facing applications. Your work will directly contribute to the development of AI agents that automate complex business processes, as well as generate dynamic, real-time commentary content for games such as FIFA, NBA, and more.

This is a hybrid role based in Prague, offering the opportunity to work with cutting-edge LLM frameworks, retrieval-augmented generation (RAG), and multimodal models that process both language and vision. You will collaborate with a small, fast-moving team of ML engineers, product developers, and domain experts to design systems that combine reasoning, tool use, and creative content generation.

Responsibilities

Must-have:
Solid experience with LLMs in production environments, including fine-tuning, inference, and tool integration.
Experience building RAG-based systems and working with vector or graph databases.
Strong understanding of function calling, structured output generation, and agentic reasoning workflows.
Hands-on experience with LangChain, LangGraph, or other orchestration frameworks.
Proficiency in Python and key libraries (e.g., PyTorch, Hugging Face Transformers, FastAPI).

Nice-to-have:
Experience with sports broadcasting or data-driven content generation (e.g., live commentary, analytics).
Familiarity with multimodal LLMs and integrating textual and visual inputs.
Familiarity with tools like vLLM, Triton, or DeepSpeed for efficient model serving.
Contributions to open-source AI tools or research publications in NLP, multimodal AI, or agent systems.

Join us at Valka to lead a new wave of interactive video content—one where your creativity and technical prowess will help transform entire industries and reimagine how digital content is created, shared, and experienced.

This role offers a unique opportunity to shape the future of interactive video content, where digital humans can engage in meaningful and dynamic interactions with users. If you're a passionate ML expert with a drive to innovate and create immersive experiences, we encourage you to apply.
