Who You Are:

You are a visual designer who enjoys working on marketing content and understands that good design has to perform, not just look good. You’re curious about new tools, open to experimenting with AI in your workflow, and comfortable working in a fast-moving team. If that sounds like you, we’d love to hear from you.

About the role:
We are looking for a Visual Designer to join our Organic Growth & Partnerships team on a freelance basis.

This role is focused on static visual content for ASO, Social Media, and Partnership ads. The ideal candidate combines strong graphic design skills with a good understanding of performance-driven marketing visuals. Hands-on experience with generative AI tools, especially for creating realistic AI people, is a strong plus.

Key Responsibilities

• Design App Store and Google Play assets (icons, screenshots, feature graphics) and adapt them for A/B tests and localizations.
• Create static content for Instagram, TikTok, YouTube, and other social platforms.
• Design ad creatives for partnerships, following partner brand guidelines where needed.
• Use generative AI tools to create images, personas, and scenes when relevant.
• Collaborate with the team to turn briefs into clear, effective visual content.

Must-Have Skills

• Experience as a Visual / Graphic Designer, or similar role in marketing.
• Strong understanding of composition, typography, color, and visual hierarchy.
• Good understanding of social media formats and app store visual requirements.
• Proficiency in Figma.
• A good eye for detail and visual quality.
• Ability to work quickly, iterate on feedback, and handle multiple formats and variations.
• Hands-on experience with generative AI tools for image creation (e.g. Magnific, Higgsfield,, or similar).
• Experience creating realistic AI-generated people and keeping a persona consistent appearance across images.
• Portfolio

We don’t focus on years of experience - what matters to us is what you can create. A portfolio is a must and can be in any format, as long as it showcases static ads, app store or social media visuals, and ideally AI-generated work.
