About this role
🎤 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 Senior Backend Engineer for our German 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. We are open for you to be based remotely across Germany, France or the UK.
🚀 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
- API design and development with REST
- Fluent in German (C1) to communicate effectively with partners
- Willingness and work authorisation to travel to Berlin (we cover your expenses!)
- Can work with us for minimum 3+ months
✨ READY TO TALK? APPLY NOW! 🚀
We look forward to your application and can’t wait to meet you – no matter who you are or what background you have!

About this listing
Published on Ashby under the board identifier Voize, which is the name the employer’s own job board carries. RoleSprint has not verified the company’s registered or trading name, so it is shown exactly as published rather than tidied up.
RoleSprint is not the employer and not a recruiter. Applications are made on the employer’s own site and never reach us; what RoleSprint does is help you decide whether a role is worth your time and prepare for it if it is.
Published 29 October 2026, last checked 3 days ago. A posting stops being advertised here 90 days after the employer published it, and one the employer takes down is marked closed rather than quietly removed.
