Harnham, San Francisco, CA, United States


Title : Senior Machine Learning Engineer, Media Generation

Location : Remote

Compensation : Up to $300,000 + Equity

We’re partnered with a well-funded startup at the forefront of media generation and digital identity, building the infrastructure for the next generation of interactive, AI-powered experiences. Their platform enables developers and creators to generate fully customizable characters, digital assets, and AI companions, positioning them at the intersection of generative AI, gaming, and social platforms.

This is a high-impact role within a growing R&D team, focused on building cutting-edge machine learning systems for media generation. You’ll work on models that power character creation, digital fashion, and interactive experiences, helping define how users create and express themselves in digital environments.

What You’ll Do

Design, train, and deploy ML models for high-quality image, video, and 3D asset generation

Work across computer vision and graphics to generate meshes, textures, and motion

Build and optimize generative models such as diffusion, GANs, and transformer-based architectures

Integrate ML systems into user-facing creative tools and applications

Collaborate with product, engineering, and creative teams to ship AI-powered features

Manage ML infrastructure including datasets, experiments, and deployment pipelines

Stay up to date with emerging research and apply new techniques to production systems

Requirements

Master’s degree or higher in Computer Science, Machine Learning, Computer Vision, or related field

3+ years of experience in machine learning, computer vision, or computer graphics

Strong Python skills and experience with frameworks such as PyTorch or TensorFlow

Experience with generative models (diffusion, GANs, VAEs) and modern architectures (Transformers, ViTs, etc.)

Solid understanding of 3D graphics, computational geometry, or related areas

Experience working in cross-functional teams and communicating technical concepts clearly

Nice to Have

Experience with 3D reconstruction, tracking, or geometry analysis

Familiarity with neural rendering techniques such as NeRF or Gaussian Splatting

Experience scaling ML models and optimizing training pipelines

Background in distributed training, data pipelines, and experiment tracking

Publications or contributions to research or open-source projects

If you're interested in building next-generation generative AI systems at the intersection of media, gaming, and identity, this is a unique opportunity to help shape a rapidly emerging space.
