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
