Job description

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

Why work at Spiral

  • Culture: Deep-tech startup with a strong open-source ethos (Vortex, FastLanes, etc.). Company describes itself as “built for the machine consumer” – ideal for engineers passionate about high-performance computing, storage, and AI infrastructure.
  • Remote/Hybrid Policy: Not explicitly stated, but offices in New York and London suggest a hybrid model; many technical hires are likely remote-friendly.
  • Notable Perks & Engineering Culture: 63% of employees are in technical roles. Talent sourced from Palantir, Microsoft, Monzo, Carnegie Mellon, and LangChain. The engineering team writes Rust, Zig, and CUDA, and works on bleeding-edge compression and database internals. Small team (18 people) with major impact on the LF AI ecosystem.
  • Career Path: Fast growth (72.7% headcount increase in a year) means early employees can shape product direction and architecture.
