Spiral is building the data infrastructure that AI actually needs. We enable teams developing models in complex domains, such as weather & climate, financial, time-series, genomics, point-clouds, videos, and images.

We're reinventing storage with innovative data layouts, compression strategies, and orchestration layers, blending open-source building blocks like Vortex with proprietary cloud data warehouse architecture.

We’re a small, high-caliber team based in New York and London, backed by world-class VCs and equipped with the runway to tackle bold ideas.

We’re looking for exceptional engineers with deep experience in low-level, high-performance software and cloud-scale storage systems.

What we're looking for:

  • 5+ years of experience writing high-quality production code

  • Strong foundation in operating systems and systems programming

  • Proven track record in performance engineering

  • Familiarity with tools like Apache Arrow, Parquet, DataFusion, Clickhouse, or DuckDB is a plus

  • Understanding of cutting-edge ML infrastructure stack (e.g. PyTorch, CUDA) is also a plus

  • Experience with Rust is a bonus

  • Willingness to work in-person at our NYC or London office

Compensation Range: £150K
