About
Cardboard is a video editor you can talk to. It runs in the browser and as a Mac app. Most footage is shot on phones, and we don't have a mobile app yet.
We're hiring a Product Engineer (Mobile) to build v1 from scratch, and to decide what Cardboard on a phone should be. We care more about taste and craft than any one stack. With agents, keeping iOS and Android in step is the easy part. Making something people love using is the hard part.
What You'll Own
You'd be surrounded by people who are absurdly good at what they do. One started coding at 11 and shipped an app with 6M+ downloads in high school. One got into CS engineering at 14 and has been working on distributed systems for 8+ years. One's an ex-founder who took a company to 1.2M users and $300M+ in transactions. That's the team. We're looking for someone who'll raise the bar on technical craftsmanship and product quality. Apart from that you'd get:
- 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.

What You'll Own
- Cardboard on iOS and Android, from architecture to the app stores.
- Handling real phone footage: 4K, HDR, and huge files.
- Uploads that survive bad networks and the app going to the background.
- You've shipped mobile apps people use every day, and you sweat how they feel.
- You're a strong mobile engineer, whether that's Swift, Kotlin, or React Native.
- You notice when an interaction feels off, and you fix it.
- Bonus: you've built a camera, photo, or video app.
- You own outcomes, not tickets: decide what to build, ship it, and check it worked.
- You talk to users and look at the data.
- You build with AI agents every day, and you're the taste and judgment in the loop.

- Competitive salary and founding-team equity.
- Unlimited tokens across every AI model. Use whatever you want, as much as you want.
- A healthy budget for AI tools and any peripherals you need to do your best work.

About
Cardboard is an agentic video editor for growth/marketing teams and serious creators who need to ship videos consistently. Instead of agencies, long timelines, and infinite review cycles, teams give cardboard a footage + a goal (“3 variants”, “30s hook”, “testimonials”) to get a strong first cut in minutes on which they can iterate quickly.
Multimodal LLMs can finally reason over footage, and WebGPU/WebCodecs make a real NLE possible in the browser. For the first time, an “AI director” inside a professional editor can be a reality.
We have to build two hard things at once: a high-performance editor in the browser and an agentic editor that is reliable for production use cases. Most startups do one; incumbents can’t rebuild their stack without breaking everything.
Saksham and Ishan met in school and have known each other since 15 years. Saksham was Co-founder/CTO of Iterate AI (backed by EF) and posts content on social media; Ishan has spent ~5yr building memory-heavy, performance-critical browser apps at HackerRank (S11) and deeply understands browsers. He has built Hotspoter (5M+ downloads) when he was 14.
Together, we’re unusually suited to build the editor core others avoid.
Video is becoming the default distribution channel, and the team that iterates fastest compounds attention. Cardboard becomes the default workspace for video production, the way Canva/Figma became the workspace for design - because it’s collaborative, fast, and does the tedious parts for you.
