We are creating new formats, stories, and building a world where the only limit is human imagination. And now we are looking for an AI Engineer ready to join and create it with us.

YOUR MISSION:

• Building agentic pipelines that transform an idea into a finished series episode without manual steps between script, generation, and editing.
• Transitioning working prototypes (MVP, PoC) into production-ready systems with a web interface used by the entire team.
• Designing a unified Knowledge Base accessible simultaneously to humans and agents, as a foundation for collaboration across various departments.
• Rapid integration of new generative models (video, text) into production on the day of their release.
• Researching and implementing new agentic system architectures: multi-agent workflows, tool calling, memory, guardrails, self-recovery.
• Analyzing patterns in user requests to agents and automating typical scenarios without human involvement.
• Reducing time and manual editing at every stage of content production – from script to final cut.
• Constant monitoring of new models, techniques, and practices in generative AI and their rapid adaptation into production.

THE FOLLOWING SKILLS AND EXPERIENCE WILL BE REQUIRED FOR THIS:

• 3-4+ years in an engineer/developer role.
• Experience with Typescript, Nest.js, and Next.js.
• Experience with PostgreSQL, Redis, Docker.
• Understanding of Observability.
• Production experience with Agentic AI Architecture: designing autonomous agents, hierarchical planning, orchestrating multi-agent systems, dynamic workflows, tool execution, and persistent state using TypeScript and LangGraph.js/Mastra.
• Experience with AI Memory & Knowledge Architecture: GraphRAG, vector databases, Neo4j, knowledge graphs, entity resolution, semantic search, and long-term agent memory.
• Experience with multimodal generative AI: orchestrating LLMs, vision-language models, and video generation models; automated quality assessment, visual consistency, iterative regeneration, and human-in-the-loop architectures.
• Experience implementing Agentic AI systems — multi-agent workflows, tool calling, MCP, RAG, state/memory, structured outputs, evaluations, guardrails, and recovery.
• Experience with generative video — video generation models/APIs, asynchronous media pipelines, FFmpeg, ensuring consistency, and automatic quality control.

WILL BE AN ADVANTAGE:

• Python for AI/ML prototypes and model work
• Fine-tuning, LoRA, PyTorch
• GPU infrastructure and inference optimization
• Computer vision, lip-sync, character consistency
• Knowledge graphs and hybrid RAG

WHAT YOU WILL GET FROM US:

• Rapid professional growth. We are building an environment where development is the norm: lectures, libraries, hackathons, schools. We compensate for specialized training and learning any language, particularly Ukrainian.
• Work format of your choice. You can work from home, in our office in Podil, Kyiv, or in Lviv (generators, shelters, lunches, snacks — all inclusive), or abroad — we have several offices there too.
• Equipment and services. Everything you need for work.
• Rest. 20 days of vacation + official holidays and unlimited sick leave.
• Care for your body and mind. We compensate for sports, health insurance in Ukraine (after the probation period), corporate doctor services, and mental health support.

WHY IS IT COOL TO WORK WITH US?

• Real impact. Your decisions affect 100+ million users — their experience, emotions, and the time they spend in the product.
• Vibrant culture. We create an environment where you can experiment and try new things. The average rating for the question "How much do you like working at HOLYWATER?" based on eNPS results is 9.23/10.
• Autonomy. We trust the team's decisions: minimal micromanagement, maximum space for initiative and impact.
• Strong people around you. We constantly challenge the status quo and reach new heights. Thinking differently and striving for more is supported here.

Perhaps this is your chance to become our next big name?
