Responsibilities

This role is about pioneering that integration. You won't be applying off-the-shelf VLMs — you'll develop novel approaches, innovate on architectures, and answer questions that haven't been solved yet: how vision and language representations inform each other, how multimodal understanding improves…

  • Lead development and training of state-of-the-art multimodal vision-language models within the FLUX stack — innovating on architectures, not just applying existing ones
  • Design fine-tuning strategies that adapt VLMs to specialized creative use cases (captioning, editing instructions, prompt enhancement) that general-purpose models can't handle
  • Research integrations between VLM/LLM capabilities and our diffusion and flow pipelines — finding creative ways to improve generation quality and controllability without…
  • Evaluate emerging multimodal architectures, translating the best of recent research into practical improvements

What they're looking for

  • You've pretrained or significantly advanced a VLM (not just SFT'd or LoRA'd one) that was deployed in a production system or released publicly
  • Strong publication record or unambiguous production track record showing you push the frontier on multimodal architectures
  • Deep understanding of how vision and language representations interact: tokenization, alignment, grounding, cross-modal attention, and the failure modes of each
  • Experience with distributed training at multi-node scale
  • Comfortable at the research/production boundary — you care whether the work ships and generalizes, not just whether it reads well
