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
