Role Overview

We invite experienced individuals to join us as Principal Machine Learning Engineers, working autonomously to lead AI system initiatives within game development. This role emphasizes applied AI, where you'll move beyond research to embed cutting-edge models into artist and developer tools. Your responsibilities will span from experimental proof-of-concepts to full-scale production deployments, balancing model fine-tuning with inference optimization to tackle actual production challenges.

Key Responsibilities

• Develop intricate agent workflows utilizing frameworks such as LangGraph and LangChain, integrating techniques like MCP, RAG/GraphRAG, and bespoke skill sets.
• Design and implement generative content pipelines, including 2D/3D image and video generation (using tools like Stable Diffusion and open-source large language models), ensuring smooth integration with digital content creation tools and gaming engines.
• Transition from prototypes to production-grade systems by building robust evaluation frameworks and deploying cost-efficient, scalable solutions employing Python, FastAPI, AWS SageMaker/Bedrock, and adhering to MLOps best practices.
• Conduct technical feasibility studies through proof-of-concepts, collaborating closely with product and creative teams to translate complex technical challenges into actionable development roadmaps.

Candidate Qualifications

• Minimum of 7 years of hands-on experience building production-level systems with a focus on machine learning and artificial intelligence, demonstrated through shipped code or equivalent accomplishments.
• Deep expertise in agent-based architectures or generative content workflows, ideally both.
• Ability to thrive in ambiguous environments by innovating with minimal initial specifications and iterating prototypes to clarify paths forward.
• Pragmatic judgment in choosing when to utilize pre-existing models, fine-tune them, or develop simple scripts based on project needs.
• Strong proficiency with Python programming; familiarity with AWS services, LangChain or LangGraph frameworks, ComfyUI, and contemporary AI technology stacks is essential.

Additional Information and Benefits

• Opportunity to contribute at the company's headquarters, influencing its strategic direction.
• Membership in the R&D center focused on pioneering gaming technologies.
• Participation in group events and social activities.
• Comprehensive medical insurance coverage for all employees.
• Relocation assistance available.
• Career growth and international transfer possibilities through Virtuos Internal Mobility Program.
• Access to multiple internal and external learning resources.
