Founding Design Engineer

All positionsFounding Design EngineerBengaluru, IndiaFull-timeAbout 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. Design Engineering 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. In a product like ours, how things move, respond, and feel is not a finishing touch. It's the product. We're hiring a Founding Design Engineer who lives at that intersection: someone who can author the feel of Cardboard, not just implement it.

This role owns craft on both sides of the funnel. Inside the product, that's the interactions, animations, and rendering details that make Cardboard feel alive. On the growth side, that's the microsites, landing pages, launch moments, and experiments that make people stop and pay attention. You'll run different experiments, ship the ones that work, and set the visual bar for how the world first meets Cardboard.

You'll be working alongside a team of engineers who all care deeply about craft, including the founders. The surface is where you'll shine. You know enough full stack to hook things up when you need to, but interactions, animations, and the details that make a product feel alive are what you're here for. What you'll actually do Own craft across growth: microsites, landing pages, launch moments, blog, and the marketing surface.

Make people stop and pay attention. Run growth experiments end to end. Design them, build them, ship them, learn from what works, and kill what doesn't. Build and ship the interactions, animations, micro-interactions, and core rendering engine work that powers Cardboard. Work across core product features like the editor timeline, micro-apps, and polished elements throughout the app. Optimize memory usage when projects reference tens of gigs of source media through smart streaming, caching, and asset management across OPFS, Cache Storage, cache headers, and related browser primitives.

Build reusable components and push the quality bar for everything that touches the surface, while respecting the user's device constraints. Experiment with new interaction patterns, shaders, and creative techniques. Ship the ones that make the product feel more alive. Write great design.md files. Set interface guidelines for the team and our agents in the spirit of interfaces.rauno.me. Raise our accessibility standards.

Wire up API endpoints when the work demands it. Solve these hard problems. Who you are You have deep knowledge of easing and timing. Ease-out, ease-in-out, linear: you know when and why. You have opinions about 80ms vs 300ms. You're fluent in GSAP, Framer Motion, and Three.js. You're comfortable with shaders, dither effects, and SVG animation performance. You're solid in WebGL and GLSL. You understand rendering pipelines from the inside, not just as an API.

You're obsessed with frontend performance. You can profile browser performance bottlenecks and systematically optimize them, especially during extended editing sessions. You think in experiments. You have a growth instinct for what makes people stop, click, and share, and you'll ship a microsite or a launch moment as happily as an in-product interaction. Bonus: you're excited about WebGPU and where it's going.

What you get 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 creative product quality.

Apart from that you'd get: 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. Apply for Founding Design Engineer
