AI Engineer

• Fast professional growth. We build an environment where development is the norm: lectures, libraries, hackathons, schools. We cover specialized training and learning any language, including Ukrainian.

• Work format of your choice. You can work from home, at the office in Kyiv's Podil or in Lviv (generators, shelters, lunches, snacks - all inclusive), or abroad - we have several offices there too.

• Equipment and services. Everything you need to get the job done.

• Time off. 20 vacation days + official holidays and unlimited sick leave.

• Care for body and mind. We cover sports, health insurance in Ukraine (after the probation period), corporate doctor services, and mental health support&

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

• Building agentic pipelines that transform an idea into a ready-made series episode without manual steps between scripting, generation, and editing.

• Translating 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 the collaborative work of different departments.

• Rapid integration of new generative models (video, text) into production immediately on the day of their release.

• Searching for and implementing new architectures for agentic systems: multi-agent workflows, tool calling, memory, guardrails, self-recovery.

• Analyzing patterns in user interactions with agents and automating typical scenarios without human involvement.

• Reducing time and manual editing at every stage of content production - from script to final edit.

• Constant monitoring of new models, techniques, and practices in generative AI and their rapid adaptation into production.
