Job description

About Us:

Fireworks is the platform for specialized intelligence, enabling companies to build, train, and serve AI models tailored to their own data, workflows, and products. Founded by the team behind PyTorch and backed by AMD, Atreides, Benchmark Capital, Index Ventures, Lightspeed, NVIDIA, Sequoia Capital, and TCV, Fireworks powers production AI with hundreds of state-of-the-art open models across text, image, embedding, audio, and multimodal workloads. Today, Fireworks is a Series D company valued at $17.5 billion, bringing together an ambitious, collaborative team that’s building the future of enterprise AI.

The Role:

You’ll be a core builder of the backend systems that power Fireworks:

• Our main web application

• Model and fine-tuning job orchestration

• Billing and enterprise features

• Accounts, org management, access controls

• Policy enforcement and governance

• APIs and developer tooling

• And many other cool things!

This is platform engineering with product impact. Your systems will directly shape how customers build on top of AI. You’ll work closely with product, frontend, infra, and GTM to ship end-to-end features — not just tickets.

What You’ll Do

• Design and build scalable backend services

• Own major product surfaces from architecture to production

• Improve reliability, performance, and developer experience

• Work directly with customers to understand pain points

• Ship enterprise-grade features without enterprise slowness

• Use AI tooling aggressively — we expect you to automate yourself

You Might Be a Fit If

• You like building real products, not just infrastructure for infrastructure’s sake

• You enjoy driving initiatives across teams to get things done

• You think in terms of systems, tradeoffs, and business impact

• You care about developer experience and clean abstractions

• You’re curious about AI and want to build where the future is going

• You want ownership, not task lists

Minimum Qualifications

• Comfortable collaborating with both humans and AI systems (Yes, We’re Serious)

• 5+ years of experience helping humans solve real problems

• 2+ years of working with AI — agents, bots, chats, or building on top of models

Why Fireworks?

• Solve Hard Problems: Tackle challenges at the forefront of AI infrastructure, from low-latency inference to scalable model serving.

• Build What’s Next: Work with bleeding-edge technology that impacts how businesses and developers harness AI globally.

• Ownership & Impact: Join a fast-growing, passionate team where your work directly shapes the future of AI—no bureaucracy, just results.
