Fullstack / Frontend Developer - Installation and Customer Care

10% of Europe’s CO₂ emissions are caused by residential heating and energy bills are out of control. Aira is here to change that.

With our intelligent Aira Heat Pump at the heart, we’re making the switch to clean energy-tech easier and more affordable. Helping Europe turn off gas and slashing energy costs one home at a time.

Founded in 2022, and with 1000+ employees and counting, Aira is driving the clean energy revolution by providing homes with modern clean energy-tech solutions such as solar power, battery storage solutions and heat pumps. With a state-of-the-art production facility in Poland, an HQ in Stockholm, Sweden, and hubs across the UK, Germany, and Italy, Aira is well on track to install clean energy-tech into 5 million homes by 2034.

About The Role 

As a Fullstack Developer on our Installations & Customer Care team, you'll help transform how clean energy gets delivered by empowering the field workforce with intuitive, data-driven tools. You’ll work at the intersection of software and real-world impact, building solutions that help us improve our digital and operational processes and that help installers and technicians do their best work every day.

In this role, you will:

• Build intelligent tools that replace manual paperwork and disconnected workflows with scalable digital solutions, bringing structure, traceability, and efficiency to field operations
• Develop services that simplify collaboration and handovers between installers, planners, and support teams, ensuring smooth transitions and fewer dropped balls across the customer journey
• Create platforms that collect and leverage operational data, helping us identify patterns, drive continuous improvement, and make smarter decisions at scale
• Design infrastructure that empowers a traditionally non-digital workforce to adopt and rely on intuitive tools, enabling them to focus on delivering high-quality installations
• Support post-installation care by enabling proactive maintenance, diagnostics, and revisit scheduling, improving long-term outcomes for both customers and the business
• Help us scale into new regions and markets by building flexible systems that adapt to varying local requirements, work practices, and service models
  
  
  

We’re changing how clean energy is installed and maintained—making it smarter, faster, and better for everyone involved. If you’re a generalist, excited about solving problems and want to build systems that empower people in the field and drive tangible outcomes, this is the role for you.
