Prime Intellect, Inc. is building the open frontier AI stack, unifying compute, environments, evaluations, sandboxes, and deployment for post-training at frontier scale.
The platform supports SFT, RL, tool use, and continuous production models with open-source models and a full-stack workflow. You will build environments, evaluations, agent systems, and post-training methods with an external robotics team, training agents using RL, world modeling, imitation learning, planning, and multimodal
Prime Intellect is building the open superintelligence stack: the infrastructure frontier AI labs build internally, made available to every ambitious AI team. Our platform, Lab, unifies compute, environments, evaluations, secure sandboxes, high-performance training, and deployment into one full-stack system for post-training at frontier scale - from SFT and RL to tool use, agent workflows, and continuously improving production models. We are building open frontier AI: open-source models trained end to end for long-horizon tasks like autonomous research, and the full-stack platform our own research team uses to build them. The next generation of AI companies, enterprises, and research teams do not just need more GPUs. They need the ability to turn their own workflows, tools, data, and feedback loops into superintelligence they own.
You will build environments, evaluations, agent systems, and post-training methods with an external robotics team.
You will train and evaluate agents with reinforcement learning, world modeling, imitation learning, planning, and multimodal perception, using feedback from simulation and deployed robots.
The experiments will test behavior under partial observations, long horizons, changing environments, and hardware and safety constraints.
Applied Research at PrimeWe turn a workflow into tasks, environments, evaluations, and reward signals, run post-training experiments against real baselines, and deploy what works. When a result looks good, we find out whether the gain came from the model or from the data, harness, inference, or infrastructure. The reusable parts become shared research, open-source systems, and product capabilities.Every Applied Research role is externally facing. Most researchers work directly with customers, users, or research partners while maintaining a substantive research agenda.
Representative early problemsBuild aligned simulation and real-world evaluations for a long-horizon embodied task, then measure exactly where policies fail to transfer.
Combine demonstrations, interventions, offline data, and online feedback into a training loop that improves behavior without erasing prior competence.
Train an embodied agent to recover from partial failures, changing scenes, and uncertain state while respecting safety and hardware constraints.
If you're excited about the opportunity to build the foundation for the future of decentralized AI and create a platform that empowers developers and researchers to push the boundaries of what's possible, we'd love to hear from you.
