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 ML backbone that makes it instant and magical.
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 the ML systems that power instant, high-quality creation at scale. From sub-second inference pipelines to personalization engines, your work will define how billions experience AI creativity.
What You’ll Do
- Core ML Infrastructure — Build inference pipelines serving millions of generations weekly; design real-time streaming for diffusion, LLMs, multimodal systems; optimize latency across serving, batching, caching, routing.
- Model Performance — Adapt foundation models (SD, Flux, LLMs) for creation; implement quantization, distillation, pruning; experiment with LoRAs, ControlNets, adapters for style and personalization.
- Intelligence Layers — Build ranking, recommendation, and personalization engines; content understanding with embeddings, similarity search, classification; moderation systems that keep outputs safe.
- Production Systems — Scale GPU infra from thousands to millions of daily generations; profile bottlenecks and optimize utilization; implement A/B testing for model variants; monitor drift, quality and latency p99s.
- Relentless Experimentation — Ship new model variants daily; A/B test speed vs. quality; build feedback loops from user behavior to improve outputs.
What We’re Looking For
- ML Engineering Depth — Experience shipping production ML at scale; strong with generative models (diffusion, LLMs, multimodal); PyTorch/JAX fluency; inference serving (Triton, Ray, TorchServe).
- Systems & Infrastructure — Expertise in inference optimization, batching, quantization, model compilation; GPU infra (CUDA, memory management, multi-GPU serving); backend skills in Python/FastAPI, async systems, cloud (AWS/GCP/Azure).
- Product-Focused ML — Care about user experience, not just benchmarks; design for sub-second latency, graceful degradation, and delight.
- Mindset — Startup DNA, fast-moving, scrappy; performance obsessed; quality focused; empathetic to creator intent and expectations.
Bonus
- Built and scaled ML products for consumer apps
- Experience with personalization or recommendation systems
- Open source or side projects showing technical creativity
Why Join
- Be Early — Like YouTube 2005 or TikTok 2018, but for AI creation.
- Own It — our models define latency, quality, and magic for millions.
- Learn From Operators — Founders who’ve scaled ML products to 100M+ users.
- Win Big — Significant equity, competitive comp, asymmetric upside.
- Invent the Future — Solve unsolved inference problems at the AI × consumer edge.
