About Us:

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.

The Role

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.

What You’ll Work On

APIs, web backend, and developer tooling
Model training, fine-tuning, and inference orchestration
Job scheduling, autoscaling, and model serving
Billing, enterprise features, and access control
Cross-cloud infrastructure (compute, storage, networking)
Global scale GPU cluster management

What You’ll Do

Build and scale backend services and distributed systems
Own systems from design → production → reliability
Work directly with customers to solve real problems
Optimize performance, cost, and developer experience
Move fast and use AI tools to automate everything you can

You Might Be a Fit If

You cannot wait to jump into the forefront of AI revolution
You like to build infrastructure and backend that are directly contributing to products
You think in systems, tradeoffs, and impact
You take ownership and drive things across teams

Requirements

5+ years building backend or infrastructure systems
Strong distributed systems fundamentals
Experience with cloud (AWS/GCP/Azure)
Familiar with ML/AI tooling or platforms
Comfortable working with both humans and AI systems

Bonus

Experience with large-scale ML infrastructure
Kubernetes / cloud-native stack
Infra-as-code, CI/CD, or open-source contributions
