synthetic-data-generation jobs in San Diego

Principal Engineer leading NLP innovation at enterprise scale, responsible for developing retrieval-augmented generation architectures, agentic AI workflows, and production language systems that process petabytes of data. Design knowledge graphs, semantic layers, and ontology-aware language understanding systems while optimizing inference for latency and cost.…See more Drive large-scale model improvements through prompt engineering, fine-tuning, and reinforcement learning, and mentor senior engineers to establish NLP best practices across the organization.

As an Autonomy Engineer focused on VLA (Vision-Language-Action) pre-training, you will train capable robotic policies using deep learning, including pre-training base models on multi-embodiment trajectory data, fine-tuning for specific tasks, and optimizing for real-time edge inference. You'll own the full loop from data collection and curation through deployment, partnering with data and MLOps teams to build continuous training pipelines that ingest synthetic data and teleop logs.…See more The role requires 3+ years building production deep-learning systems with hands-on experience in LLMs, VLMs, or generative models, plus strong Python and PyTorch/JAX skills to profile, debug, and write maintainable research code.
