Senior Research Engineer, LLM

About the Role

Genies is looking for a passionate Senior Research Engineer to join our core AI team at our Bay Area office in San Mateo, CA. This is a critical role where you will take end-to-end ownership of the research and development of our core generative AI systems, driving the roadmap that will define the intelligence and interactivity of millions of AI avatars. You will solve fundamental technical challenges in creating socially-aware, autonomous, and creative AI characters and companions. Working closely with a dedicated team of engineers and researchers, you will bridge the gap between cutting-edge research and real-world product impact.

What You'll Be Doing

• Architect and develop next-generation agentic reasoning frameworks, enabling avatars to formulate plans, utilize tools, and interact dynamically within Genies' social gaming ecosystems.
• Design and implement advanced LLM post-training and alignment algorithms (e.g., RLHF, DPO / GRPO) to fine-tune avatar personality, behavior, and conversational quality.
• Pioneer research into socially-grounded intelligence, empowering avatars with memory, context-awareness, and the ability to engage in complex, multi-turn interactions.
• Develop robust data pipelines to process diverse, multimodal user interaction data, identifying key signals for improving model performance and agent capabilities.
• Create novel evaluation methodologies and benchmarks to rigorously measure avatar quality across dimensions like role-playing consistency, safety, and task completion.
• Collaborate with product and engineering teams to translate research breakthroughs into scalable, production-ready systems that directly impact the user experience.
• Stay at the forefront of academic and industry research in LLMs and AI agents, identifying and prototyping new techniques to advance our technology.
