• Experience in fast-paced or startup environments.
• Experience with CUDA programming or GPU-accelerated compute.
• Prior work fine-tuning models and curating datasets for applied ML.
• Familiarity with SLAM, NeRF, SfM, or MVS techniques.
• Comfort balancing research-to-production pipelines and customer deliverables.
• Strong collaborative skills, with ability to work across multidisciplinary teams.

What We Offer

Compensation:

• Salary Range: $125,000 - $180,000.
• Annual bonus and equity as appropriate.
