Research Engineer - Reinforcement Learning

Prime Intellect•San Francisco, CA

9d•Hybrid

About The Position

Building Open Superintelligence Infrastructure Prime Intellect is building the open superintelligence stack - from frontier agentic models to the infra that enables anyone to create, train, and deploy them. We aggregate and orchestrate global compute into a single control plane and pair it with the full rl post-training stack: environments, secure sandboxes, verifiable evals, and our async RL trainer. We enable researchers, startups and enterprises to run end-to-end reinforcement learning at frontier scale, adapting models to real tools, workflows, and deployment contexts. As a Research Engineer in our Reasoning team, you'll play a crucial role in shaping our technological direction, focusing on our test-time compute scaling research ideas. If you love working with synthetic data and teach LLMs reasoning abilities, this role is for you. For more details about the project you would be working on, check out our outlook on decentralized training in the inference-compute paradigm.

Requirements

Strong background in AI/ML engineering, with extensive experience in designing and implementing end-to-end pipelines for the inference or training of large-scale AI models.
Deep expertise in distributed inference techniques and frameworks (e.g. vllm, sglang) for optimizing the performance and scalability of AI workloads.
Solid understanding of MLOps best practices, including model versioning, experiment tracking, and continuous integration/deployment (CI/CD) pipelines.
Passion for advancing the state-of-the-art in reasoning and democratizing access to AI capabilities for researchers, developers, and businesses worldwide.
If you're not familiar with these, but feel like that you can contribute to our mission and you're a high-energy person, get familiar with these resources ( here , here and here ) and please reach out!

Responsibilities

Lead and participate in novel research to build a massive scale synthetic data generation pipeline and orchestration solution
Optimize the performance, cost, and resource utilization of AI inference workloads by leveraging the most recent advances for compute & memory optimization techniques.
Contribute to the development of our open-source libraries and frameworks for synthetic data generation and distributed RL frameworks.
Publish research in top-tier AI conferences such as ICML & NeurIPS.
Distill highly technical project outcomes in layman approachable technical blogs to our customers and developers.
Stay up-to-date with the latest advancements in AI/ML infrastructure and tools, synthetic data gen research and proactively identify opportunities to enhance our platform's capabilities and user experience.
