Jobs at Fireworks AI

Here at Fireworks, we’re building the future of generative AI infrastructure. Fireworks offers the generative AI platform with the highest-quality models and the fastest, most scalable inference. We’ve been independently benchmarked to have the fastest LLM inference and have been getting great traction with innovative research projects, like our own function calling and multi-modal models. Fireworks is funded by top investors, like Benchmark and Sequoia, and we’re an ambitious, fun team composed primarily of veterans from Pytorch and Google Vertex AI.

Fireworks is building the inference and orchestration layer for companies deploying open-weight and fine-tuned models in production. As teams move beyond prototyping with closed models, they need faster, cheaper, and more flexible infrastructure. Fireworks delivers on all three. Its inference engine, FireAttention, provides up to 8x lower latency, while FireFunction supports compound AI workflows across multiple models, APIs, and tools. Customers like Uber, DoorDash, Superhuman, Cursor, and Sourcegraph have standardized on the platform to run AI workloads at scale.

As of May 2025, Fireworks is generating approximately $130M in ARR, growing over 20x+ YoY, and operating profitably with more than $80M in cash on hand. Led by former Meta and Google engineers, including key contributors to PyTorch, the team brings deep technical expertise and a clear read on market needs. With over 12,000 users and a product suite purpose-built for latency-sensitive, enterprise-grade deployments, Fireworks is emerging as the default infrastructure provider for AI inference in production.
