Generative AI - 3D Foundation Model

Who You Are

You are a talented, hands‑on researcher who thrives in a fast‑paced environment, is self‑directed, a team player, and knows how to get things done efficiently. You have deep understanding of the transformer architecture
, have strong python and tensor programming skills
, have a vision for AI beyond linear sequences
, and you believe in “the scaling law”. You can translate high‑level goals into concrete research and implementation steps, set an approach, and follow through. When it’s time to explain your ideas, you bring clarity to complex technical issues.
You are not afraid of confronting new ideas, and you are eager to share your knowledge with the team
. You use these skills to create real‑world benefits for our researchers, engineers, and millions of users, and you are excited to help advance our effort to push the state of the art of AI that understands and generates 3D worlds.

As a core member of the team of research scientists and machine learning engineers at Meshy, you will drive the development of our core 3D‑native generative foundational model
. In this role, you will join our foundational research to advance 3D AI, apply learnings from other fields of ML, and push the state of the art. You will also work towards long‑term ambitious research goals, while identifying intermediate milestones.

The essential functions include, but are not limited to the following:

• Design, train, and refine large‑scale 3D generative models from covering pre‑training, post‑training, and emerging paradigms in diffusion, flow matching, and multi‑modal learning.

• Bridge the gap between cutting‑edge research and product, deploy models in real products used by millions of creators, using human feedback and creative evaluation.

• Create novel model architectures to make 3D generation faster, higher‑quality, and more controllable.

• Collaborate with infrastructure and systems teams to build scalable training, and data pipelines across GPU clusters and cloud environments.

• Bring engineering discipline into an fast‑paced research environment: elegant code, reproducible experiments, and building software as a team.

• Share insights and breakthroughs through internal demos, open‑source contributions, or technical reports that advance the field of 3D generative AI.

• Strong engineering skills in Python and deep learning frameworks (preferably PyTorch); comfortable moving between research prototypes and production systems.

• Familiar with Transformers and modern generative AI models (Diffusion / flow matching, VAE, etc.).

• Curiosity and passion for multi‑modal AI, and have an intuitive understanding of how models perceive, represent, and generate 3D worlds.

• Familiar with high performance training on large scale infrastructure (e.g., SLURM, Ray, k8s) is a plus.

• Contributions to popular open‑source machine learning projects or publications in top‑tier CV / ML conferences is a plus.

Persons in these roles preferably should be able to spend part of their time on‑site in our Sunnyvale HQ
. On‑site requirements vary based on position and team, and we support fully remote options for exceptional candidates
. We also have employees in Seattle, Boston, NY, Toronto, etc. If you have questions about hybrid or remote work arrangements for this role, please ask your recruiter.

We are a fast paced startup and we work hard. You need to be able to:

• communicate information and ideas so others will understand.

• observe details at close range.

• work under deadlines.
