Train, deploy, and continuously improve your own models on an integrated compute, training, inference, and sandbox stack. Backed by Menlo.
About the role
You'll build the distributed control plane and node-level runtime behind our sandbox platform: placing workloads across bare-metal workers, launching secure microVMs, and making the entire lifecycle fast, efficient, and resilient to failure. Build the control plane that places sandbox workloads efficiently across bare-metal CPU and GPU workers.
What they're looking for
- You have 5+ years of experience building production distributed systems from the ground up
- You have strong systems programming experience. Production Go is a major advantage, Rust, C++, or comparable systems-language experience is also valued
- You are a high-agency engineer who can lead the design and implementation of high-performance, fault-tolerant systems
- You have strong Linux systems fundamentals and depth in at least one of virtualization, networking, storage, or workload isolation
- You enjoy going deep on systems performance, whether the bottleneck is memory behavior, concurrency, networking, or resource utilization
- You have built, deployed, and operated production systems at scale
More about this role
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.
Prime Intellect has raised $150M in total funding from Founders Fund, Radical Ventures, NVIDIA, and exceptional AI, infrastructure, and enterprise operators — including Andrej Karpathy, Dwarkesh Patel, and leaders and founders from Ramp, Perplexity, Harvey, Mercor, Zapier, Datadog, Cognition, OpenAI, Thinking Machines, Together AI, SemiAnalysis,...
