Software Development San Mateo, CA 51–200 employees Founded 2022 Privately Held

Fireworks AI runs a GPU-backed inference and model-tuning platform built on PyTorch, vLLM and SGLang across NVIDIA and AMD hardware, with Kubernetes spanning AWS, GCP and Azure. Listings on Azure Marketplace and ties to Azure AI Foundry point to hyperscaler co-selling. Hiring is engineering-heavy and senior-skewed, though velocity is slowing, and job posts flag a missing SecOps function and strained revenue accounting as the business scales.
