Mobile Developer

Introduction

The digital customer journey at Wellis is growing rapidly and becoming more complex. To take it to the next level, we're looking for a Mobile Developer (iOS & Android). You will own everything that touches our mobile experience — from the very first app open to long‑term retention. With your knowledge of native iOS and Android development, mobile UX, and connected health features, you'll make the Wellis app smarter, more personal, and truly engaging. It's time for an experienced mobile specialist to raise our app experience to benchmark level in the healthcare and wellness world.

About Wellis

Wellis is a fast-growing healthtech scale-up that is reinventing one of the most traditional sectors: healthcare. What started just three years ago has already grown into a company with tens of thousands of customers, and we are only at the beginning. By combining medical expertise with technology and data, we make healthcare smarter, more efficient, and more personal.

Our mission is to improve everyday lives by making care accessible, personal, and seamless. Through our platform, people can take control of their health journey with trusted medical support, smart digital tools, and tailored programs. We move fast, challenge conventions, and build solutions that truly make an impact, because we believe better healthcare should be within everyone's reach.

About the Role

As a Mobile Developer, you'll take the lead in shaping the next generation of the Wellis app. You'll translate designs into seamless native experiences across iOS and Android, integrate smart health features, and build the foundation for a scalable, content-rich wellness platform. Your job is to ensure the Wellis app feels intuitive, personal, and genuinely supportive throughout the user's health journey — far beyond a simple e-commerce transaction.

Key Responsibilities

• Take end-to-end ownership of the Wellis app — from first MVP to a mature, scalable product.
• Translate UX/UI designs from Figma into high-quality, native iOS and Android experiences.
• Design, build, and maintain complex app features around health, wellness, and coaching — far beyond a simple e‑commerce checkout.
• Integrate with Apple HealthKit, Google Fit, wearables, and other device capabilities to create smart, data-driven user journeys.
• Collaborate closely with backend engineers to connect the app to our GCP-based, API-first platform.
• Implement localization and multi-market capabilities so the app can scale across countries and languages.
• Ensure app performance, reliability, and security, especially around sensitive health data.
• Act as a sparring partner for product, UX, and C-level on mobile strategy, roadmap, and technical choices.

About the Team

You'll report directly to the CTO, who brings deep experience in building scalable digital platforms and high-impact mobile products. You'll work closely with our UX/UI partners, backend engineers, data team, and medical & customer care teams — with plenty of room to take initiative yourself. As we're building our mobile capabilities from the ground up, the product & tech domain is growing fast, and you'll have the opportunity to play a key role in shaping our mobile app vision and future mobile team.
