## Job description

## Why You're Here

As a Sr. Full Stack Engineer, you'll operate with autonomy in a small, fast-moving team, working directly with the CTO and founding product engineer to scale Fuser’s core platform. This is a hands-on engineering role — you will spend most of your time designing, coding, and shipping features across the stack. We’ve launched our public beta with a strong foundation — 100k+ lines of code, multiplayer infrastructure, a node-based canvas, and dozens of AI integrations. Now we’re building toward collaboration, subgraphs, post-production, and operation nodes. You’ll help ship features, shape abstractions, and keep Fuser fast, stable, and expressive for creative professionals.

## What You’ll Do

- Build and ship key features across the stack with the founding team
- Own complex systems such as multiplayer, asset pipelines, or execution flows
- Architect clean, scalable abstractions that simplify complexity without limiting control
- Improve performance, reliability, and developer experience
- Help define the architecture for future AI-native UI/UX patterns
- Collaborate tightly with design and product — we move quickly and iterate often

## What You’ll Bring

- 5+ years of experience shipping full-stack applications
- Strong skills in React + TypeScript, with backend depth in Node, tRPC, or Cloudflare Workers
- Understanding of distributed or real-time systems
- Experience designing APIs, databases, and data flows
- Curiosity about creative tools, design systems, or AI interfaces
- A builder mindset — you enjoy coding daily and owning your work end-to-end

Bonus Points For:

- Experience with canvas or node-based tools (React Flow, Three.js, WebGPU)
- Familiarity with AI or creative software
- Open-source contributions or creative coding background

## Our Stack

Frontend: React 19, React Router 7, Zustand, React Flow, Three.js Backend: Cloudflare Workers, tRPC, Drizzle ORM, PartyKit, Durable Objects Database & Storage: Supabase (PostgreSQL), R2 AI Integrations: 50+ APIs (OpenAI, Anthropic, Runway, FAL, and more)

## How We Work

- Remote-friendly — we welcome candidates anywhere in the U.S.
- LA-based core team — the team works hybrid, and you’ll collaborate remotely via async tools, Slack, and regular touchpoints.
- Optional in-person team weeks — in Los Angeles for planning, onboarding, or deep collaboration.
- Creative-first culture — we care about accessibility, design, and feel.
- High trust, high standards — ownership early, autonomy always.
- Small team, big impact — every commit shapes the future of the product.

## Compensation & Benefits

- $80K–$180K USD depending on experience and zone (equity included)
- Signing bonus upon joining
- Healthcare, dental, vision, and 401(k) (U.S. only)
- Flexible hours and focus on deep work
- Generous equity and real product ownership
- Mentorship and leadership growth as we scale while staying hands-on

## How We Interview

- Intro Call – Meet one or two of us to talk about your background, our mission, and how we work.
- Technical Conversation – Complete a live technical assessment based on a real-world problem followed by a discussion on your approach to architecture, problem-solving, and building for usability.
- Technical Demo – A scoped technical project with compensation
- Team Conversation – Meet with core team and have a discussion about collaboration, culture, and long-term vision.

We welcome candidates who may not have the “right” title but have the skills, mindset, and drive to thrive here. At Fuser, the process is the point. Fuser is a creative technology company founded by artists, educators, and engineers. We’re building tools for professionals who ideate, orchestrate, and deliver with intention. Our flagship product is a collaborative canvas for working across text, image, video, audio, and 3D, powered by the latest AI models. We’re a small team in Los Angeles designing the future of creative software: joyful, intuitive, and powerful tools for real-world storytelling and production.
