Job Level
About the role
- Act as the technical owner for enterprise customer VLM post-training engagements.
- Translate customer requirements into concrete multimodal post-training specifications and workflows.
- Design and execute visual data generation, filtering, and quality assessment processes, including image-text pair curation, annotation pipelines, and synthetic data generation for visual tasks.
- Run supervised fine-tuning, preference alignment, and reinforcement learning workflows for vision-language models.
- Design task-specific evaluations for visual understanding, grounding, OCR, document parsing, and other multimodal capabilities. Interpret results and feed learnings back into core post-training pipelines.
Requirements
- Hands-on experience with data generation and evaluation for VLM or multimodal post-training.
- Experience training or fine-tuning vision-language models using SFT, preference alignment, and/or RL.
- Strong intuition for visual data quality, annotation design, and multimodal evaluation.
- Familiarity with vision encoders, image-text architectures, and how visual representations interact with language model backbones.
- Experience with visual grounding, document understanding, OCR, or video understanding tasks is nice-to-have.
- Experience contributing to shared or general-purpose multimodal post-training infrastructure is nice-to-have.
- Prior exposure to customer-facing or applied ML delivery environments is nice-to-have.
- Familiarity with alignment or RL techniques beyond basic supervised fine-tuning in the multimodal setting is nice-to-have.
