Your team will work at scale, combining pre-training and post-training approaches while ensuring models meet regulated industry requirements. This is about more than just building models — it’s about creating infrastructure, teams, and frameworks that define the future of AI in high-stakes settings.

Your focus will include leading pre-training and post-training of foundation models, architecting reasoning-capable LLMs, scaling a 15–20 person research and engineering team over 12 months, and integrating models into domain-specific applications.

You should bring:

• Staff/Principal-level experience with hands-on model training.

• Deep expertise in pre-training or post-training (ideally both).

• Track record of driving impactful projects to completion.

• Strong understanding of LLM architectures and large-scale training.

• Experience leading complex technical initiatives across teams.

Nice to have: experience in regulated/safety-critical AI, reasoning or planning architectures, open-source model development, or prior technical leadership.

Package: $350k base (negotiable) + substantial stock, healthcare, 401k, 20 vacation days, and flexible working.

You must be based in the SF Bay Area. US citizens and green card holders only.

• Handle messy, lossy, or incomplete real-world data - moving beyond clean synthetic geometry to tackle industrial reality
• Scale training across multiple 3D tasks: segmentation, classification, correspondence, and eventually generation
• Create evaluation pipelines that meaningfully assess model performance and enable continuous production monitoring
• Work toward a foundational 3D model supporting both discriminative and generative tasks, integrated into broader agentic AI architecture

Your expertise should include:

• Deep specialisation in 3D computer vision (ideally including a PhD in Computer Vision)
• Strong knowledge of modern 3D architectures (PointNet++, MeshCNN, 3D Gaussian Splatting, diffusion models, VLMs)
• Proven ability training large-scale deep learning models with PyTorch
• Solid applied research skills - can implement novel architectures from papers and make them work in practice
• Experience with multimodal or vision-language model development

Nice to have:

• Background working with CAD data or industrial design workflows
• Experience in complex topics such as robotics, autonomous driving, or AR/VR with 3D perception focus
• Familiarity with SLAM, pose estimation, or differentiable rendering

You'll join a research team that values ownership and rapid iteration, with the resources to pursue ambitious technical goals. The company provides abundant compute resources and the freedom to explore foundational approaches whilst ensuring practical impact.

Package includes:

• Base salary: $300,000
• Performance bonus up to 20%
• Medical, dental, and vision coverage
• 401k with up to 3% company match
• 20+ vacation days

You'll need to be based in SF Bay Area or Miami, with a collaborative team environment that encourages innovation and technical excellence.

You must have valid right to work in the US without sponsorship (US Citizenship or Green Card).
