# App Developer (Flutter)

At DeWarmte, we make smart, affordable heat pumps that help homes move away from gas. We design the hardware, software and services ourselves, so the quality of our software directly shapes how well our products work in people's homes. We're growing fast, and both apps need to grow with us. That's why we're looking for an App Developer to build and improve our two Flutter apps. Homeowners use the customer app to control their heat pump. Installers and service engineers use the employee app to install and maintain heat pumps in the field. You'll spend most of your time writing code: improving quality and reliability and shipping features to iOS and Android. Your work has a direct effect on comfort at home and on how efficiently our installation and service teams work. AI tools are already part of how we build software. We use them where they help us move faster, but we do not lower the bar: anything we ship still needs to be secure, maintainable and correct. You'll help us get better at both. Why this role matters Build reliable, intuitive apps that give customers confident control of their heat pump and help our installation and service teams do great work in the field. You'll join
