About HeartStamp

HeartStamp is building the future of greeting cards and invitations — AI-powered, hyper-personalized, and professionally printed. We're a team of 24 designers, engineers, writers, and AI specialists creating a platform where every card is one-of-a-kind and gift-worthy. We're launching nationwide in the U.S. in March 2026 and moving fast.

The Role

We're looking for a freelance visual design consultant to serve as a creative quality lead for our growing card and invitation library. Your job is to review AI-generated designs produced through our platform, provide expert visual feedback, recommend improvements, and help us maintain a top-tier quality standard across every occasion and style.

This is a unique opportunity for a talented visual designer to work at the forefront of AI-powered product design — and learn generative AI prompt engineering along the way. Our platform handles the generation, so you don't need prompting skills to start. What you need is a trained eye, strong design instincts, and the ability to articulate what makes a card go from good to "I need to buy that." Over time, you'll build real, marketable AI generation skills simply by doing the work with us.

Our writers produce concepts and copy. Our prompt engineering team generates the visuals through our platform's built-in creation tools. You review submissions through our editor and admin panel, evaluate the output, and provide clear direction on what needs to change — composition, color, typography feel, visual hierarchy, emotional tone, occasion fit, overall flow. You're the design taste filter for our entire product.

What we're looking for

— Professional visual design background — graphic design, illustration, art direction, or a related discipline. Formal training or equivalent professional experience. You think natively in composition, color theory, visual hierarchy, and typography.

— A sharp, critical eye with commercial instinct. You can look at a card design and immediately identify what's elevating it and what's holding it back. You understand the difference between "visually interesting" and "someone would actually buy this."

— Greeting card, invitation, or stationery design experience is a huge differentiator. If you've designed cards, invitations, packaging, or retail print products that have been produced and sold, you're exactly who we want.

— Range across visual styles. Our library spans watercolor, illustrative, photorealistic, minimalist, whimsical, elegant, humorous, and bold graphic styles across every major occasion — birthday, wedding, baby, holiday, sympathy, graduation, thank you, retirement, and more. You need to give credible feedback across all of them.

— Understanding of occasion-based design language. A sympathy card and a kid's birthday invite have completely different visual DNA. You get that instinctively.

— Clear, actionable communication. You can articulate exactly why something isn't working and what should change. "The warm tones clash with the somber occasion — try a muted blue-gray palette with more whitespace and pull the focal element down" is the kind of feedback that moves us forward.

— Willingness to learn and grow. You'll be working with AI-generated imagery daily and naturally developing prompt engineering and generative AI skills as part of the role. We see this as a two-way investment — you raise our quality bar, and we help you build skills that are increasingly valuable across the design industry.

-Must have a strong understanding of Western design aesthetics and cultural trends, with your finger on the pulse of what resonates with Millennial and Gen Z audiences across social media.

Nice to have

— Existing familiarity with AI image generation tools (any platform)

— Print production knowledge: CMYK color, bleed, safe zones, 300+ DPI

— Understanding of card anatomy: front cover, inside left, inside right, back panel

— Experience with typography in greeting cards and invitations

— Background in retail product design or consumer packaging

Engagement details

— Hourly, $25-45/hr depending on experience and location

~15–25 hours/week to start, scaling as we approach launch. Role has potential to increase in hours & compensation as we grow

— Remote, async-friendly. We're a distributed global team

— Ongoing engagement, not a one-off. We're building a library of thousands of designs and need a consistent creative partner who grows with us.

To apply, please include

— Your portfolio (Dribbble, personal site — whatever shows your best work)

— 2–3 examples from your portfolio that best demonstrate range and commercial design sensibility

— A short note on any experience with greeting cards, invitations, stationery, or print products

— Bonus: Pick any greeting card you've seen (in a store, online, anywhere) and tell us in 2–3 sentences what works visually and what you'd improve. This tells us more about how you think than any resume.

We're reviewing on a rolling basis and moving quickly. If you have a trained designer's eye, strong commercial instincts, and want to work at the intersection of design craft and AI — we'd love to hear from you.
