With Sonia, doctors are successful doctors. We create and deploy AI enhanced solutions that make doctors’ lives easier, patients’ care better, and healthcare systems more efficient.

As a Design Engineer at Sonia, you’ll be responsible for creating user-centric,
conversion-optimized designs that not only look great but perform. This is a hybrid role where design excellence meets technical execution: you’ll design and implement landing pages, marketing assets, and user flows that directly support growth and engagement.
You’ll work closely with our marketing and engineering teams to craft consistent and compelling experiences—across the entire user journey, from first impression to loyal user.

• Design and launch high-converting landing pages and marketing funnels
• Create visual assets for ads, campaigns, and brand communication
• Optimize checkout and onboarding flows for maximum conversion
• Write and refine UI copy to guide users and support product messaging
• Translate ideas into prototypes and polished user interfaces (Figma to code)
• Implement your designs using React, TypeScript, and CSS
• Collaborate closely with marketing to ensure consistent branding and messaging
• Work independently, take ownership of quality and iterate quickly based on feedback

You are a multidisciplinary designer who bridges the gap between aesthetics and performance. You’re comfortable owning a concept from early sketch to final implementation, and you understand that every pixel needs a purpose. You have experience working in dynamic environments (startups, small teams), are highly self-directed, and hold a high bar for quality in your work.

Must-Haves

• Proficiency in German (C2 or native) and English (C1+)
• Strong portfolio showcasing UI/UX, landing pages, and responsive web design
• Ability to implement designs in code (JavaScript, TypeScript, React)
• Deep experience with Figma, GitHub, CSS/HTML
• Demonstrated ability to design and ship complete flows from idea to launch
• Structured thinking, strong sense for user behavior and visual hierarchy

Nice to have

• Background in marketing, content creation, or copywriting
• Experience in the healthtech industry
• Degree in Interface/Product Design or similar (less graphic/print)
• Personal website or online portfolio with live examples (please provide link/ material)
• Experience working in or with startups or on smaller, fast-paced projects

High degree of ownership and creative freedom

• A product-focused environment where quality and performance matter
• A collaborative team that values learning, pragmatism, and support
• Attractive compensation aligned with your skills
• Flexible work arrangements
• 30 days of vacation per year

If you enjoy building meaningful relationships, driving customer satisfaction, and contributing to the transformation of healthcare, we’d love to hear from you!

Please send us your CV and a portfolio that shows your ability to design and ship thoughtful digital experiences.

I'm Margarita and will be guiding you through the application process.
