Full Stack Engineer (C#, React Native, React js)

About the Organisation

This team is shaking things up in the Benelux when it comes to safety and emergency response tech. They build clever tools like panic buttons, mobile apps, SIM-based services, reporting dashboards and automated scenarios that help companies keep their people safe.

They’re already a strong player in this fast-growing space and are now levelling up even further with cool new hardware, software products, strong partnerships, and a growing knowledge base. The goal? A safer society — one smart solution at a time.

They work with a modern tech stack including C# ASP.NET, ReactJS, Redux/Saga, TCP communication, WebSockets, REST and Kubernetes.

The Role

They’re on the hunt for a Medior Full-Stack Developer — someone who’s solid with .NET and React, and excited to make a real impact across their platform.

It’s a partly remote role where you’ll help build and improve their microservices setup, including ASP.NET Core REST APIs and a ReactJS frontend.

But this job isn’t just coding behind a screen — you’ll also get involved in things like on-site support, assembling/testing devices, and contributing to mobile app development. If you’re flexible, curious and enjoy dipping into different parts of the product lifecycle, you’ll feel right at home.

• Able to work onsite at least 2 days per week

Bonus Points If You Have

• Experience with REST APIs
• Azure/Kubernetes exposure
• Interest in hardware/peripherals (BLE/radio/GSM)
• Strong CI/CD knowledge
• Curiosity about UX/UI
• Independent, focused and communicative mindset
• Interest in cross-platform mobile development
