Mission
Make creation the world’s favorite entertainment.
About GenTube
Imagination to images in milliseconds. Already 10M+ monthly creations and accelerating. We believe AI creation is the next social medium — as big as video, as habitual as scrolling.
The Opportunity
We’re at the start of a generational shift. Just as YouTube unlocked the world’s videos and TikTok turned short-form into the default entertainment, GenTube is making AI creation the medium of our time. A billion people will move from passive consumption to active creation — and you’ll be one of the engineers building the rails.
The Founders
Josh and Mo scaled platforms to 100M+ users and led a $150M+ AI exit to Microsoft. Now they’re building the defining consumer AI company of the creation era. We’re well-funded with a long runway and you’re joining the founding team.
The Role
You’ll own product-defining features used by millions daily. Build systems that feel instant. Your code will set the standard for how people create, share, and play with AI globally.
What You’ll Do
- Own end-to-end systems: React Native UI, Next.js infra, Node/Python APIs, AI streaming, databases
- Ship loops that feel like magic: sub-50ms taps, real-time AI streaming, intuitive experiences
- Build infra that scales: from 10M+ monthly creations today to 1B+ tomorrow
- Move at founder speed: daily deploys, 24-hour experiments
- Drive by metrics: session time, creates per DAU, retention. Optimize what moves the graph
- Grow into technical leadership — setting architecture, scaling systems, mentoring
What We’re Looking For
- Full-stack fluency across modern frameworks and infra
- React Native mastery with deep performance optimization
- Frontend: TypeScript, React internals, Next.js SSR/ISR, Tailwind
- Backend: Node/Python APIs, GraphQL, caching, real-time systems
- Prototype to production, fast
- Bias toward speed and iteration, balanced with craft
- You think in loops — retention, virality, engagement
Bonus
- Built AI products or shipped with ML APIs (Groq, Replicate, etc.)
- Real-time streaming interfaces with sub-second latency
- Open source/projects that show technical creativity
Why Join
- Be Early — Your work defines the product.
- Own It — Zero layers. Ship daily. Reach millions.
- Learn From Operators — Founders who’ve scaled to 100M+ users.
- Win Big — Significant equity, competitive comp, asymmetric upside.
- Lead the Wave — Consumer X AI is the next global platform shift.
Details
