Founding Design Engineer

San Francisco, CA, US / Full-time

About the Role

We’re looking for a Design Engineer who cares deeply about every product detail, from user experience to pixel-level design.

In consumer products, details matter a lot. Small details are the wow moments for consumers, making them realize they needed the product even before they knew it.

You’ll own real product decisions, listen to users, and ship things that directly impact our product and brand identity.

What You'll Do

• Build and evolve Sume’s design system: the components, patterns, and motion language
• Ship polished, production-ready UI across product, marketing, and our website
• Work six days a week in-person in San Francisco, 12 hours a day
• Be obsessed with user logs and interviews

You're likely a good fit if...

• Determined to build a $10B company like Cursor within a year
• Motivated by creating generational wealth (we're serious about making you rich)
• Led the design of a fast-growing startup or your own project
• Genuinely enjoy trying new things every day

About Sume

We turned down a big-tech exit offer to build a generational company.
We built 2 products with 10k+ users just in a single month.
The consumer AI race just started, and we are the ones moving the fastest.
