🎤 Why voize? Because we’re more than just a job!

At voize, we believe the greatest gift to frontline workers is time - time to care, connect, and be present. Today, that time is lost to admin work that pulls nurses away from what matters most: people.

💡 Your Mission

As a Freelance Backend Engineer for our French Market squad, you’ll ensure that data flows smoothly between our products and our partners' software solutions. You'll build and maintain the integrations that connect the voize with senior care and hospital software platforms.

🚀 Your Daily Business – No two days are alike

  • Shape the future of our integrations – Develop interfaces that seamlessly connect voize with systems in the care and medical sector

  • Build future-proof solutions – Develop a scalable API, set industry standards, and work closely with partners and clients

  • Take end-to-end ownership – From the idea and implementation to the ongoing development of our integrations

  • Architecture with foresight – Design thoughtful data models and sustainable solutions for complex systems

  • Work with impact – Your work saves caregivers time, improves documentation, and supports people who do amazing work every day.

🤝 Your Skillset – What you bring to the table

  • Several years of experience in backend development and API integration

  • Excellent proficiency with Kotlin and Coroutines

  • API design and development with REST or GraphQL

  • Business fluent in French (C1) to communicate effectively with partners

  • Based in France or Germany

  • Willingness to travel to Paris (we cover your expenses!)

  • Can work with us for minimum 3+ months
