Role

Who you are

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
Comfortable collaborating with both humans and AI systems (Yes, We’re Serious)
18+ years of experience helping humans solve real problems
2+ years of working with AI — agents, bots, chats, or building on top of models

What the job involves

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
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

Our take

Whilst the development of generative AI is thought to be the reserve of large companies like Open AI, smaller startups such as Firework AI are making this technology easier to access and develop for smaller companies wanting to handle specific business needs using AI. As an open-source model API, it has one of the largest user bases - with over 12,000 users leveraging Fireworks AI’s software.

Though lacking the brand name recognition of generative AI developers like Google and Meta, Fireworks AI differentiates itself in a market crowded with large competitors through its unique approach to deploying its software. It creates smaller, production-grade, customizable generative AI models that can be launched privately and securely, rather than the non-private and inflexible models built by larger companies.

After its 2025 Series C round of $250M, Fireworks AI has been valued at over $4B, an impressive sum for a David in a sea of Goliaths. The company plans to use its funding to reshape AI infrastructure as well as expand globally. It will be interesting to see how the company evolves with its potentially disruptive business approach to generative AI.
