Mercor is organizing human intelligence to power the AI economy. We are powering frontier research, AI benchmarks, and AI agent training at scale for the top AI labs and enterprises. Backed by General Catalyst and Menlo.
About the role
Frontier AI is going physical, and the labs building it are bottlenecked on one thing: high-quality data from the real world. Mercor pairs its operational scale with the specialized engineering that physical-world data demands.
What they're looking for
- Strong backend and data engineering fundamentals in a modern language (Python, Go, Rust) and comfort operating production systems on AWS and GCP
- Experience building and owning high-volume data pipelines, not just contributing to them
- Experience with large binary formats, streaming ingestion, distributed batch processing, and object storage economics
- Customer-facing instincts: you can lead a technical conversation, ask the right questions, and push back when a request is unreasonable
- Comfort working through ambiguity and shipping iteratively with a product team, where requirements evolve with the customers and data types
