## Job description

### 🎤 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**
