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

Location: Toronto — downtown office, high-energy, creative hub
Benefits: We offers generous health, dental, and vision benefits, unlimited PTO, paid parental leave, and relocation support as needed.
Visa: Available support for top candidates

If you want to help define the medium that follows video and social, this is the moment. Join us before GenTube becomes the next billion-person creation platform. We encourage you to apply even if you do not believe you meet every single qualification.
