Senior Full-Stack Developer – Fuser (Remote / Anywhere)
Build the future of visual AI workflows with us
🚀 About Fuser
Fuser is a next-generation visual AI workflow platform redefining how creators and teams co-create with intelligent tools. Imagine an infinite canvas where you can connect text, images, video, audio, and 3D using nodes and edges — all powered by the latest in generative AI.
We’re a tiny but fast-moving team building a powerful editor that feels like Figma for AI. We’re growing fast, and we’re looking for a full-stack developer ready to jump into the deep end and build with us — fast, globally, and with conviction.
👩💻 The Role
We’re hiring a senior-level full-stack engineer to help shape the technical foundation of Fuser. You’ll have ownership over core systems — from our React-based canvas to our Cloudflare-powered backend — and collaborate directly with the founders. We move fast, break things with care, and value people who can ship, sweat the details, and thrive in ambiguity.
This is a high-impact, early engineering role where your decisions will shape the product, culture, and architecture. We don’t care where you live — as long as you’re down with the pace and vision.
🔧 What You’ll Be Building
- Visual Editor (Frontend): React, React Flow, Zustand, Three.js, custom canvas + 3D components
- Backend Infrastructure: Cloudflare Workers, tRPC, Drizzle ORM, Supabase, PostgreSQL
- AI Integrations: Over 50 AI tools (OpenAI, Anthropic, Runway, FAL, etc.)
- Realtime Collaboration: PartyKit, Durable Objects, live-sync canvas workflows
- Performance, Reliability & DX: Fast load times, type-safety, elegant systems, auto-deploy pipelines
- Stripe Integration: Payments, subscriptions, credit features
🧠 We’re Looking For
Must-Haves
- Fluency in React 19+, TypeScript, and modern React ecosystem
- Hands-on experience with node-based or canvas tools (React Flow, Three.js, etc.)
- Experience with type-safe backends — tRPC, Cloudflare Workers, Drizzle
- Understanding of PostgreSQL, distributed systems, and auth/security
- Confidence building and shipping full-stack features solo
Bonus Points
- Built creative tools, IDEs, or internal platforms before
- AI-curious or experienced with tools like OpenAI, Runway, etc.
- Experience with Supabase, Durable Objects, PartyKit, or R2
- You've thrived in a small team / fast-paced startup before
💡 The Mindset We Love
- Bias to Action: You prototype fast, iterate faster, and own your work end-to-end
- Product-Obsessed: You think in UX and architecture at the same time
- Curious & Collaborative: You want to build tools people love, not just ship tickets
- Startup-Ready: You’re scrappy, global, async-friendly, and resilient under pressure
🌍 Work with Us From Anywhere
We’re remote-first and global by design. We care about what you build, not where you live. As long as you bring clarity, momentum, and care to your work, you’ll fit right in.
💸 What We Offer
- Competitive salary + equity
- Early team role with tons of ownership
- Access to the latest AI tooling and creative tech
- Flexible, async-friendly hours
- A creative, kind, ambitious team who wants to build things that matter
