ABOUT THE POSITION
We are looking for a Senior AI Engineer to help design and deliver agentic AI systems that power R&D tooling for video game asset pipelines and production workflows. You will help shape the technical direction of our internal agent platform and drive engineering practices around agent loops, memory, evaluation, and safe deployment of LLM-driven applications.
This is a senior, hands-on individual contributor role: you will write code, help design the agentic architecture, and partner with stakeholders across studios to turn emerging AI capabilities into production-grade tools.
Co budeš dělat
- Agent platform
Design and build key parts of our internal agent libraries - the core abstractions and developer ergonomics that let teams across the company build agents quickly and consistently.
Help shape the architecture of our central agent runtime - the runtime, registry, and observability surface where agents are deployed, monitored, and governed.
Help define and evolve the agent loop / harn
- Agent loop & harness engineering
Drive prompting strategy at scale: system prompt design, guardrails, mitigation of context poisoning and pollution, and management of hyperparameters (context window sizing, lost-in-the-middle effects, temperature, top-k).
Design tool interfaces for agents: MCP servers, structured inputs/outputs for context, and sub-agent composition patterns.
Advocate for best pra
- Agent memory
Design and build the key parts of the memory layer used across our agents: conversation history management, context chaining, and episodic memory.
Help define the boundary between short-term working context and long-term persistent memory, including decay/retention policies.
Apply RBAC and tenant isolation to memory so agents can be safely shared across teams and projects.
- Test- and eval-driven development
Build out the evaluation discipline for agentic systems: golden traces, regression evals, offline + online metrics, and red-team prompts.
Build the harnesses and CI gates that let us iterate on prompts, models, and tools with confidence.
Uphold evals as the unit of progress - no agent change ships without a measurable signal.
- Backend & platform foundations
Design and build scalable backend services and secure RESTful APIs in Python (FastAPI), with strong data modeling across relational and non-relational stores.
Enforce authentication/authorization (RBAC), input validation, and robust error handling for agent-facing endpoints.
Implement caching, queues, and vector storage where the agent workload requires it.
- Quality, delivery & collaboration
Drive performance tuning, code reviews, and technical documentation within your area of the AI platform.
Maintain CI/CD with Git/GitLab and Docker; ensure reproducible local-dev and deployment pipelines.
Partner with UI/UX, production, SRE, IT, and game-team stakeholders to translate workflows into agentic solutions.
Contribute to architectural decisions and share
