Senior Full Stack Engineer
About the Role
Featherless.ai is building the world’s most reliable and comprehensive open-model inference platform — the infrastructure powering the next generation of AI creators, startups, and enterprises. Our serverless approach to inference unlocks the best GPU utilization in AI infrastructure.
We're hiring a Senior Full-Stack Engineer to own the evolution of our user-facing platform — the model catalog, documentation, and tools that make Featherless the best place to find and use AI models.
The Platform Team builds the interfaces between our users and our inference cloud - both UI and API. This includes model discovery, API key management, usage analytics, billing dashboards, and the overall developer experience that keeps builders coming back.
What You'll Do
As a Senior Full-Stack Engineer on the Platform team, you will:
Own product development end-to-end — from diagraming user flows to shipping production features
Drive UX decisions — wireframe new features, iterate on existing interfaces, and advocate for user needs
Build and maintain our web platform — model catalog and explorer, dashboard, documentation site, and developer tools
Collaborate with the API team — ensure seamless integration between frontend experiences and backend capabilities
Respond to user feedback — triage issues, identify patterns, and rapidly ship improvements
Scale with our growth — evolve the platform architecture as we onboard more models, users, and use cases
What You'll Bring
Required:
5+ years of full-stack engineering experience with production web applications
Strong frontend skills with modern JavaScript frameworks
Backend experience with Node.js and API development
Ability to wireframe and prototype UX flows (Figma, Sketch, or similar tools)
Experience with databases and caching layers
First-hand experience building with LLMs and familiarity with popular open models
Track record of shipping features independently with minimal oversight
Preferred:
Experience with our stack: Nuxt, Vue, TypeScript, Node.js, MongoDB, Redis, Vercel, Cloudflare, Kubernetes
Background in developer tools, API platforms, or infrastructure products
Design sensibility and passion for craft in user interfaces
Experience with analytics tools and data-driven product decisions
Familiarity with billing/subscription systems
Working Style:
Bias to action — ship early, iterate based on real usage
User-focused — prioritize fixing pain points over building new features
Collaborative — work effectively with a small, senior team
Data-driven — believe that "done" means proven by usage metrics
Self-directed — comfortable with ambiguity and defining your own path forward
