About Backflip
Backflip (backflip.ai) is a generative AI startup revolutionizing how engineers and designers create for the physical world. Founded by the team behind Markforged, we’re building AI-first tools that make 3D CAD as intuitive and fast as sketching on paper. Backed by
a16z and
NEA, we’ve raised a $30M Series A and built a deeply technical, mission-driven team of 15. Our goal is to empower one engineer to work at the speed of a hundred.
The Role
We are looking for a
Machine Learning / Data Infrastructure Engineer to train and deploy frontier multimodal models for 3D CAD. In this role, you will work alongside ML researchers end to end on challenges like developing novel representations for complex 3D data, training models that generate structured design outputs, building scalable data pipelines, and delivering low-latency inference in production.
You will collaborate closely with AI research, product, and design to rapidly prototype and productionize features, helping define what state-of-the-art generative design looks like.
What We’re Looking For
- 2–7 years of experience in Data/ML infrastructure with strong CS fundamentals
- Direct, hands-on experience training, and deploying models in production
- Proficiency in Python and PyTorch
- Experience taking ML projects from prototype to production
- Deep understanding of the ML lifecycle and infrastructure
Bonus
Experience with CAD, 3D geometry, graphics, differentiable programming, or large-scale data pipelines
Why Backflip
Repeat founders in 3D printing/CAD with a prior
$2.1B exit; backed by
a16z and
NEA. In-person in SF with a tight-knit, world-class team building the future of 3D design.
Flexible PTO and competitive compensation
3 days a week in our San Francisco office, 2 days remote with the option to come in more often
