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.

  • 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

Requirements

  • 3 - 7 years of software engineering experience
  • 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

Nice to have

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

What we offer

  • Solve Hard Problems: Tackle challenges at the forefront of AI infrastructure
  • 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
  • Learn from the Best: Collaborate with world-class engineers and AI researchers who thrive on curiosity and innovation
