Python Developer (GenAI)

About the company Fast-growing AI product in the adult entertainment space. The product combines AI companions, conversational AI, image/video generation and subscription-based monetization. You’ll join the AI team building the intelligence behind the product and work closely with backend, product and QA teams. What you’ll do • Develop and maintain parts of the AI/chat pipeline: prompt construction, character personality, memory, context and response processing. • Integrate and evaluate LLM, image and video generation providers, comparing quality, cost and latency. • Train and retrain LoRAs for character consistency across image and video generation. • Build multi-step AI/agentic workflows for content generation, including automated validation. • Run structured prompt experiments and evaluations using tools such as Langfuse. • Manage inference infrastructure pragmatically: GPU providers (RunPod and similar), provider migrations, worker handlers, and cost/latency optimization. What we’re looking for • 3+ years of professional Python development, including production backend services, async patterns, queues, microservices. • Hands‑on experience integrating LLMs or Generative AI models into production — prompt engineering, structured outputs, fallback logic and handling model failures. • Practical experience with diffusion models and LoRA — training/fine‑tuning, checkpoint evaluation (SDXL or similar) or image‑to‑video generation. • Experience building multi-step AI/agentic workflows (chained generation, tool use, automated validation). • Production experience with Docker, CI, GPU inference providers (RunPod, fal.ai or similar), monitoring and debugging. • Good written and spoken English.
