Job Details

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:

We're seeking a Full‑Stack Software Engineer to play a highly impactful role in shaping the Fireworks platform. You'll contribute across the stack, from our developer‑facing web application and Python SDK to our backend systems. By doing so, you'll enable developers to successfully self‑serve GPU deployments and fine‑tune custom models. As the public platform serves as the product‑led growth (PLG) engine for Fireworks, this role offers both high visibility and the opportunity to drive direct business impact.

Key Responsibilities:

• Contribute to the Fireworks Platform (developer‑facing web app, serverless and on‑demand inference, Python SDK) alongside other team members
• Design and implement full‑stack technical features to address business problems
• Ship features that users care about, iterate rapidly and ideate constantly
• Rapidly prototype and experiment with a data‑driven focus
• Own feature development from backend APIs to frontend user interfaces
• Directly engage with users through various channels (Discord, meetups, etc.) and convert their needs into shipped features
• Be able to explain why a feature matters to customers as well as its importance in the competitive landscape
• Be a user of the inference platform to have a deep sense of what's working and what's not working in the product
• 3‑7 years of software engineering experience (We are hiring at multiple levels for this role)
• Deeply understand how a product fits into the business landscape
• Proficiency in TypeScript and Python
• Be a customer‑obsessed engineer who loves talking to users and getting feedback
• Strong ability to make design decisions and craft great experiences
• Willing to think outside of the box and build a product from scratch for users to serve new needs and use cases
• Understanding of responsive design, component‑based architecture, and UX fundamentals
• Strong communication and collaboration skills

Preferred Qualifications:

• 5+ years of software engineering experience
• Prior experience in product engineering roles with high degree of customer interactions
• Startup experience or prior contributions to internal or open‑source component libraries
• Prior technical leadership / technical PM experience
