Design Engineer UI/UX (all) - remote

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.

Tasks

• 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

Requirements

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.

Must-Haves

• Proficiency in German (C2 or native) and English (C1+)

• Ability to implement designs in code (JavaScript, TypeScript, React)

• 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

Benefits

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
