Fullstack Engineer

We're building the future of storytelling and video editing.

We're a small team that moves fast and builds things we're proud of.

We care obsessively about taste: in design, in product, in every detail.

We're solving these hard problems.

We're backed by a Tier-1 global fund, YC, and founders of billion dollar companies.

Video is the most powerful way humans tell stories. It always has been. But creating it today is still painfully hard. Fragmented tools, steep learning curves, and workflows that get in the way of the actual creative work. We're building Cardboard to change that.

Cardboard runs a real video editor in the browser, backed by a serious cloud media pipeline and an AI agent that actually understands footage. We’re hiring a Fullstack Engineer who can own a feature from the pixel a user clicks all the way down to the service that renders it. You move up and down the stack without flinching, and you ship things that work.

You’ll be working alongside a team of engineers who all care deeply about craft, including the founders. You like owning problems end to end, and you’d rather ship something great this week than something perfect next quarter

Build and ship features across the whole stack, from the editor a user touches to the services behind it.

Work on genuinely hard browser problems: real-time editing, smooth playback, and working with large media on the client.

Help shape the AI editing experience that lets the agent make real edits.

Keep the product fast and reliable, even on big, demanding projects.

Solve these hard problems.
