Job description

Location: Europe, Remote
Engagement: B2B / Contractor initially, with potential transition to full-time

About the role

We're building a large-scale, mobile-first consumer product at the frontier of AI: chat experiences, character creation, and live and interactive formats, including AI video. You'll need to be comfortable designing for adult audiences and content.

You'll join a small, fast-moving team, working directly with the Design Lead, Product Managers and founders. The role carries high ownership: you'll shape new product surfaces from first concept to shipped experience.

What you'll do

• Drive end-to-end product design across chat experiences, character creation, monetisation and growth flows
• Design emerging product surfaces, including live and interactive features and AI video experiences
• Take 01 ideas from early concept to polished, shipped product
• Translate strategic product thinking into high-quality visual and interaction design
• Design mobile-first experiences for a large-scale consumer product
• Build polished interfaces, interactions and prototypes
• Work across the full design process, from discovery and concept through to execution and iteration
• Partner closely with the Design Lead, Product Managers and founders
• Operate autonomously and own entire product surfaces
• Contribute to an environment where new interaction models are developed frequently

What we're looking for

We're looking for genuinely senior product designers with strong shipped-product portfolios, 01 experience, AI and prototyping exposure, and measurable product impact.

Essential

• 5+ years of end-to-end consumer product design experience
• A track record of designing and shipping mobile-first products at scale
• Proven 01 experience, taking products or major features from idea to launch
• Strong strategic product thinking combined with elite visual execution
• A portfolio of polished, modern, high-quality UI from real consumer products
• Demonstrable, measurable product impact (growth, retention, conversion, engagement or similar)
• Daily use of AI tools for design, prototyping or content generation, and the ability to clearly explain which tools and workflows you use
• Advanced Figma skills
• Strong prototyping skills, using design tools and/or code-based approaches
• Experience working autonomously and owning product surfaces
• Strong async communication skills and the ability to thrive in a fully remote team
• Comfort working on 18+ mature product experiences
• Willingness to start on a B2B / contractor basis

Nice to have

• Experience with dating, AI companionship, social or other mature consumer platforms
• Subscription, paywall or monetisation product experience
• Gamification experience
• Motion, 3D or illustration skills
• Front-end fluency in HTML, CSS or JavaScript

What we offer

• Fully remote, work from anywhere
• 4 weeks PTO
• Health allowance
• Learning budget
• Premium AI tooling provided
• A high-autonomy environment with direct access to senior design, product and founding teams
• Career progression within a growing international technology company
• Guidance and tools to help you reach your potential
