How we know
It hasn't been reposted, listed twice, or left up unusually long, and the posting doesn't say it's a talent pool.
Ghostless records the day it first sees a posting, so a repost can't reset its age. This one was already up when Ghostless started tracking Spiral, so its true age is longer.

About the role
About Spiral
Spiral builds a fast analytical database for multimodal, multi-rate data streams, on top of the open source Vortex file format. Our users are AI/ML researchers and AI infra engineers developing models in complex domains, such as weather & climate, financial, time-series, genomics, point-clouds, videos, and images. They spend their days waiting on data loaders, writing video or sensor data pipelines, and watching expensive GPUs sit idle on I/O. We make that pain go away.
What we're looking for
We’re looking for exceptional engineers with deep experience in low-level, high-performance software and cloud-scale storage systems.
- 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, SF, or London office
