Director of Business Operations (Series A, SaaS, on-site in SF)

📍 Location: San Francisco, CA (Full-time, in-person, light travel)

About Backflip:

Backflip AI is building 3D AI tools for the physical world. If ChatGPT is the universal platform for text, Backflip is the universal platform for designing real things — from cars, planes, and buildings to everyday items like watches, furniture, and toys — you name it.

This is the second buildout for MIT founders Greg Mark and David Benhaim, who previously co-founded Markforged, the company that invented carbon fiber 3D printing and went public at a $2.1B valuation. They are now hiring a Director of Business Operations to help take Backflip from zero to one.

This is not a traditional operations role. It’s a high-intensity, high-autonomy position where you’ll act as the right hand to the CEO — part Chief of Staff, part COO, part generalist builder. You’ll help the company run, scale, and win. You’ll be expected to learn quickly, solve real problems, and deliver outcomes that move the business forward.

Second Time Founders:

You’ll work directly with Greg Mark and David Benhaim, two lifelong builders who grew up less than a mile from each other in Massachusetts and met at MIT. Greg built bikes and solar cars in high school; David built face-tracking robots. Their passion for making things hasn’t changed — now they’re doing it at a global scale.

Greg and David previously founded Markforged, taking it from zero to a $2.1B IPO. Now, they’re back — not 14 anymore, but channeling that same energy — and building their biggest act yet.

The Role:

This is effectively the CEO’s #2 at a ~15 person Series A company.

You’ll need to be:

- A self-starter who executes without handholding.

- Highly organized — owns details, logistics, and execution company-wide.

- Adaptable — thrives in sync with the CEO’s fast-paced, high-context working style.

- A sharp business generalist — confident across Strategy, Ops, Finance, HR, Marketing, GTM.

- A systems thinker — able to architect and scale processes from 0→1.

- Calm under pressure, resourceful, and relentlessly outcome-driven.

- Ambitious — sees this as a launchpad to become a founder or exec operator.
