Senior AI Product Designer (Consumer apps) em Leiria, Portugal

We're looking for an exceptional AI Product Designer to help design the next generation of consumer mobile products.

This is not a traditional UI/UX role where success means producing polished Figma screens and handing them off to engineering.

We want someone who can go from:

Idea → UX → prototype → real user test → iteration

in days, not weeks.

You should be deeply comfortable designing consumer mobile experiences, but also be highly fluent with the new generation of AI tools that are changing how products are designed and built.

What You'll Do

You'll own product design across key parts of our consumer mobile experience, working closely with product, engineering, growth, and leadership.

You will:

- Design intuitive, beautiful consumer mobile experiences from concept through production - Turn rough ideas into interactive prototypes extremely quickly - Use Figma + AI coding/prototyping tools to test ideas beyond static mockups - Build functional prototypes using tools like Claude / Claude Code, Codex, Lovable, Cursor, Replit, or similar - Prototype real product behavior, interactions, animations, AI conversations, onboarding flows, and personalization - Work directly with engineers to ship high-quality experiences - Test prototypes with users before significant engineering resources are committed - Use AI throughout your workflow to dramatically increase the speed and quality of product iteration - Think through the underlying product problem—not just how the interface should look - Help determine what we should build, not simply design what someone else specifies

What We're Looking For

Strong consumer mobile product experience

You have designed products used by real consumers at meaningful scale.

You understand:

- Mobile UX patterns - Onboarding and activation - Habit formation and retention - Subscription/paywall experiences - Personalization - Gamification - AI-native UX - Designing for speed, simplicity, and delight

Experience with consumer subscription apps, education, wellness, fitness, social, productivity, or other high-frequency consumer products is especially relevant.

You are AI-native

Using AI should already be a fundamental part of how you work.

We expect you to be actively experimenting with tools such as:

- Claude / Claude Code - OpenAI Codex - Lovable - Cursor - Replit - Figma AI - AI image/video generation tools - Emerging prototyping and agentic development tools

You don't need to be a production engineer.

But you should be capable of building functional prototypes yourself.

If your workflow still looks like:

requirements → wireframes → Figma → developer handoff

you are probably not the right fit.

We are looking for someone whose workflow increasingly looks like:

problem → prototype → test → learn → iterate → ship

Strong product thinking

The strongest candidates think like a designer and a product manager.

You should naturally ask:

- What user problem are we solving? - Is this actually valuable? - What is the simplest version we can test? - What behavior are we trying to change? - How will we know if this worked? - Can we prototype this before engineering builds it? - What happens after the first session? - Why would someone come back tomorrow?

You should be comfortable challenging assumptions and proposing better product solutions rather than simply executing a brief.

Big Plus: Motion & Interaction Design

Motion design experience is a major advantage.

We want our products to feel alive, especially as AI makes software increasingly conversational, personalized, and dynamic.

Experience with any of the following is valuable:

- Rive - After Effects - Principle - ProtoPie - Framer - Lottie - Advanced Figma prototyping - Native mobile animation patterns - Microinteractions and gesture design

You don't need to be a dedicated motion designer, but having strong instincts around movement, interaction, and delight will make you stand out.

You Might Be a Great Fit If...

- You obsess over consumer products and constantly notice why certain experiences feel dramatically better than others - You are equally comfortable thinking about the product concept and the last 10% of visual polish - You have already changed your workflow significantly because of AI - You prototype ideas yourself rather than waiting for engineers - You move unusually fast without sacrificing taste - You understand that the best prototype isn't necessarily a Figma prototype—it might be something a user can actually interact with - You care about outcomes, not design deliverables - You have strong opinions but change your mind quickly when the data or user feedback says otherwise - You're excited about designing products where AI itself is a core part of the user experience

What We Don't Want

This role is probably not a fit if:

- Your primary strength is creating beautiful static screens - You rely on engineers for every functional prototype - You haven't meaningfully incorporated AI tools into your workflow - You prefer receiving detailed product requirements instead of helping define the product - You optimize primarily for design-process artifacts rather than shipped user outcomes

Being great at Figma is table stakes. It is not enough.

Ideal Background

There is no single required background, but strong candidates will often have some combination of:

- 4+ years of product design experience - Significant consumer mobile app experience - Experience shipping products used by hundreds of thousands or millions of users - Strong visual/UI design skills - Experience designing AI-powered product experiences - Experience building working prototypes with AI coding tools - Product management or founder experience - Motion/interaction design experience - Experience working in a high-growth startup or product-led company

Portfolio

When applying, please send:

- 2–3 consumer mobile products you've designed and explain specifically what you owned - A functional prototype you've built yourself, ideally using AI coding/prototyping tools - An example of how AI has changed your product design workflow - Your portfolio - Your favorite consumer mobile product right now and one thing you would improve about it

We care much more about what you've actually built and how you think than your title, degree, or years of experience.
