About The Position

We're building a consumer hardware company where the brand is the product as much as the hardware is. Our web presence needs to reflect that: marketing site, product pages, commerce flows, campaign landing pages. The kind of work where the details — the motion, the type, the spacing, the interactions — are the product.
We're looking for a design engineer to own how all of that gets built. You'll work alongside a strong design, product, and marketing team who care deeply about craft.
We hope you'll also bring that same eye to some of our internal R&D products. We're a research-heavy company, and the surfaces our product development team uses every day deserve the same craft as anything public-facing.

Requirements

• Strong frontend engineering. You write clean, performant code and care about what browsers actually render
• Real design sensibility. You can look at a design mockup and know what's off, and you can improve a design in code without being told
• Experience with modern frontend frameworks (React, Next.js, or similar)
• Headless CMS or headless commerce architectures
• A portfolio or body of work that shows range: visual craft, interactivity, technical ambition
• You've done this at a high level before, more than once, through the full lifecycle

Nice To Haves

• You've brought design craft to every project you touch — external and internal
• Motion design or animation skills (CSS, WebGL, GSAP, Framer Motion, whatever your tool is)
• Commerce experience: you've built the real thing with carts, checkout, and payment integrations
• SEO, page performance optimization, web analytics
• Familiarity with marketing workflows: how paid and organic campaigns land on the web, what matters for conversion
• You've worked somewhere the website wasn't an afterthought
• Experience building and working with APIs
• Growth engineering instincts: funnels, attribution, what happens after the click

Responsibilities

• Build and ship our web presence
• Own the online commerce experience end to end, from browsing through checkout
• Translate design intent into production code that holds up to the mockup
• Build interactions, animations, and UI details that make the experience feel considered and intentional
• Work with designers and marketers to bring campaigns to life on the web
• Integrate with commerce platforms, CMS tools, and analytics/tracking infrastructure
• Infuse our internal R&D product portfolio with design quality, usability, and product thinking
• Ship work that's fast, accessible, and works on every screen size

Benefits

• 401 (k) max employer match: 3.5% of compensation
• 100% employer-paid health, vision, and dental benefits for you and your dependents
• Unlimited PTO and sick time
• Flexible spending account with employer matching up to $1,650/year (medical FSA)
• Guardian Employee Assistance Program (EAP)
• Opportunity to share in the company's success with competitive stock options
