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 ## About Spiral ## Company Overview - **One-liner**: Spiral builds the multimodal data platform for frontier AI, enabling machine-scale ingestion, storage, and query of video, images, audio, point clouds, sensor streams, tables, and text as a single, versioned, object-store-native system. - **Entity Type**: Private (Series A; total funding reported as $42.5M per LinkedIn, conflicting with $22M per CB Insights) - **Headquarters**: New York, New York, United States (with offices in London, UK) - **Founded**: 2023 - **Founders**: Will Manning (CEO), Robert Kruszewski (President, Co-Founder), Nicholas Gates (CTO, Co-Founder) ## Core Business - **Primary industry**: Data Infrastructure & Analytics, AI/ML Infrastructure - **Target customers**: Frontier AI labs, research teams, and enterprise AI groups working at petabyte scale with multiple data modalities (computer vision, robotics, autonomous vehicles, etc.) - **Mission or purpose statement**: Built for the machine consumer – a database that treats bytes and tensors as first-class citizens, not a human-facing SQL warehouse. ## Products & Services - **[Spiral Platform](https://spiraldb.com/)**: The core product – a unified multimodal data platform that ingests raw object storage data and materializes model-ready tensors directly into accelerator memory. Supports declarative sampling, time-travel (`asof(T)`), and hybrid deployments across neocloud, tradcloud, and on-prem clusters. - **[Vortex](https://github.com/spiraldb/vortex)**: An open columnar format created by the team and donated to the LF AI & Data Foundation. Designed for analytical queries and AI workloads, Vortex offers up to 38% smaller files and 10–25× faster decompression than Parquet with ZSTD. - **Open-source compression libraries**: FastLanes, ALP, FSST, and others – Rust/Zig implementations of state-of-the-art integer and floating-point compression algorithms. ## Market Standing - **Valuation/Market Cap**: Not disclosed - **Key Metric**: Total Funding – $42.5M (LinkedIn reports rounds including $4.5M seed in 2023, $5.5M seed early 2025, $16.1M Series A in 2024, and $16.5M Series A in 2025). A conflicting source (CB Insights) reports $22M total; both are cited. - **Notable Investors/Partners**: General Catalyst, Amplify Partners, BoxGroup, Redpoint Ventures, Lux Capital (and others) - **Growth Signals**: 72.7% headcount growth YoY (18 employees), 86.8% monthly website traffic growth, active hiring in London and New York. Vortex accepted as an incubation project at the Linux Foundation. ## Competitive Advantages - **Multimodal-by-design**: Unlike traditional databases optimized for tabular data, Spiral natively stores and queries video, point clouds, audio, and tensors in a single tree with a unified query language. - **Object-store native, hybrid architecture**: Eliminates the need to copy or denormalize data between storage and training pipelines. - **Open-source core**: Vortex and related compression libraries are community-governed, lowering adoption risk and attracting top open-source contributors. - **Reproducibility built-in**: Immutable raw bytes on typed coordinate frames with `asof(T)` time-travel for every modality. ## Strategic Focus - **Frontier AI infrastructure**: Solving the bottleneck of moving petabytes of heterogeneous data to accelerator memory. Spiral targets the largest AI research orgs (Mistral appears as a community partner) and pretraining pipelines. - **Open-source ecosystem growth**: Driving adoption of Vortex as the standard columnar format for AI, with integrations into Apache Iceberg and PyTorch. - **Talent acquisition**: Aggressively hiring Rust, Zig, CUDA, and systems engineers to scale the platform. ## Why Work Here - **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. ## Sources 1.
