About Backflip

Mechanical design, the work done in CAD, is the rate‑limiter for progress in the physical world. However, there are only 2‑4 million people on Earth who know how to CAD. What if hundreds of millions could? What if creating something in the real world were as easy as imagining the use case, or sketching it on paper?

Backflip is building a foundation model for mechanical design : unifying the world’s scattered engineering knowledge into an intelligent, end‑to‑end design environment. Our goal is to enable anyone to imagine a solution and hit “print.”

Founded by a second‑time CEO in the same space (first company : Markforged), Backflip combines deep industry insight with breakthrough AI research. Backed by a16z and NEA, we raised a $30M Series A and built a deeply technical, mission‑driven team.

We’re building the AI foundation that tomorrow’s space elevators, nanobots, and spaceships will be built in.

If you’re excited to define the next generation of hard tech, come build it with us.

The Role

We’re looking for a Staff Machine Learning Data Engineer to lead and build the data pipelines powering Backflip’s foundation model for manufacturing and CAD. You’ll design the systems, tools, and strategies that turn the world’s engineering knowledge—text, geometry, and design intent—into high‑quality training data. This is a core leadership role within the AI team, driving the data architecture, augmentation, and evaluation that underpin our model’s performance and evolution. You’ll collaborate with Machine Learning Engineers to run data‑driven experiments, analyze results, and deliver AI products that shape the future of the physical world.

What You’ll Do

• Architect and own Backflip’s ML data pipeline, from ingestion to processing to evaluation.
• Define data strategy : establish best practices for data augmentation, filtering, and sampling at scale.
• Design scalable data systems for multimodal training (text, geometry, CAD, and more).
• Develop and automate data collection, curation, and validation workflows.
• Collaborate with MLEs to design and execute experiments that measure and improve model performance.
• Build tools and metrics for dataset analysis, monitoring, and quality assurance.
• Contribute to model development through insights grounded in data, shaping what, how, and when we train.

Why Backflip

This is a rare opportunity to own the data backbone of a frontier foundation model, and help define how AI learns to design the physical world.

You’ll join a world‑class, mission‑driven team operating at the intersection of research, engineering, and deep product sense, building systems that let people design the physical world as easily as they imagine it.

Your work will directly shape the performance, capability, and impact of Backflip’s foundation model, the core of how the world will build in the future.

Let’s build the tools the future will be made in.
