Mercor is training models that predict how well someone will perform on a job better than a human can. We use our platform to source, vet, and onboard expert contractors who help train AI models in a wide variety of domains. Our technology is so effective it's used by all of the top 5 AI labs. We scaled from $1 500M in revenue run rate in the last 17 months, making us the fastest growing company in the world. Our growth is accelerating: we averaged 11% week over week growth in July, 18% WoW growth in August, and 19% WoW growth in September. The team is small and we remain profitable because we can't hire great people as quickly as revenue is growing.

As an Infrastructure Engineer at Mercor, you'll build and scale the systems that power our rapid growth. You'll ensure our infrastructure is highly available, cost effective, and able to handle explosive traffic and compute demands. You'll work closely with engineers across product, research, and operations to design scalable architectures, streamline deployments, and improve observability.

We're hiring broadly across Infrastructure: Developer Productivity Engineer, Database Engineer, and Platform Engineer. Candidates will be team matched after the first screen, so we encourage you to apply even if your experience is stronger in one area than another.
