Senior Multimodal AI Engineer – Imagine Team

SpaceXAI; Palo Alto (CA); On-site; USD 220,000 - 357,000; Full time

Job summary

SpaceXSI's Imagine Model Team seeks a Senior Model Engineer to develop multimodal AI experiences beyond text, focusing on image and video understanding and generation with audio enhancements. You will handle data curation, modeling, training, inference serving, and product integration across pre-training and post-training phases, collaborating with product teams to push model frontiers.

You will work on cutting-edge algorithms, real-time inference, distillation, and scalable serving for visual

Qualifications

• Experience writing production-quality code in Python, PyTorch, JAX, Rust, or C++.
• Experience in multimodal applications such as graphics engines, rendering techniques, image/video understanding and generation, world models, real-time simulation, or controllable/long-horizon visual content creation.

Responsibilities

• Create and drive engineering agendas to advance multimodal capabilities, with emphasis on image and video generation, editing, understanding, controllable/long-horizon synthesis, agentic planning, RL training, and world simulation (including audio integration for richer video experiences)
• Improve data quality through annotation, filtering, augmentation, synthetic generation, captioning, and in-depth data studies, particularly for visual and audio data
• Design evaluation frameworks, metrics, benchmarks, evals, and reward models tailored to image/video/audio quality and coherence
• Implement efficient algorithms for state-of-the-art model performance, including real-time inference, distillation, and scalable serving for visual content
• Develop scalable data collection and processing pipelines for multimodal (primarily image/video-focused) datasets
• Collaborate cross-functionally to integrate AI solutions into production and rapidly iterate based on user feedback
