Junior & Senior Full-Stack Developer – Fuser (US / Canada / South America)
👩💻 The Role
We’re hiring for 2 roles at Fuser, Junior and Senior full-stack engineers. 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, Durable Objects, D1, KV, Queues, Workflows), 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
- Experience with Cloudflare
- 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
