Member of Technical Staff, Software Engineer

At Fireworks, we’re building the future of generative AI infrastructure. Our platform delivers the highest-quality models with the fastest and most scalable inference in the industry. We’ve been independently benchmarked as the leader in LLM inference speed and are driving cutting-edge innovation through projects like our own function calling and multimodal models. Fireworks is a Series C company valued at $4 billion and backed by top investors including Benchmark, Sequoia, Lightspeed, Index, and Evantic. We’re an ambitious, collaborative team of builders, founded by veterans of Meta PyTorch and Google Vertex AI.

You’ll help build the core systems powering Fireworks AI — from customer-facing APIs and product features to the distributed infrastructure running AI workloads at scale.

This is a true full-stack backend + infra role. You’ll design systems, ship product, and own everything end-to-end, not just tickets.
