Job description

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 1200+ 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, and 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 Senior Flutter Developer in the Engagement Team, you will build the tools that enable our field teams to deliver smooth installations and exceptional service. You'll be part of one of our cross-functional teams working primarily with the mobile application that installers and service technicians use. In practice, this means building tools for commissioning and servicing the full range of Aira's clean energy systems - heat pumps, solar panels, batteries, and inverters, as well as managing software updates and helping technicians troubleshoot in the field.

As a Senior Flutter developer, you will:

• Own and ship features across iOS and Android from a single Flutter codebase
• Partner with UX design to craft interfaces built for real field conditions, used by technicians on-site, often under time pressure
• Work tightly with the in-field teams to optimize the commissioning experience.
• Build reliable device integrations over Bluetooth, Wi-Fi, and Thread - connecting technicians directly to the hardware they're installing and servicing
• Make pragmatic decisions about when to prioritize speed and when to focus on long-term scalability
• Contribute to architectural decisions that support our rapid growth and international expansion

What you bring to the team:

• Solid experience with product-driven software development and agile environments
• 5+ years of mobile development experience
• Flutter experience preferred, React Native considered.
• Experience building and consuming REST APIs and integrating third-party SDKs
• Familiarity with state management patterns such as Bloc or Riverpod, and an appreciation for testable code
• Comfort working with structured data contracts and binary protocols - we use Protobuf for communication between the app and our edge devices

We would also appreciate if you have experience with or knowledge of some of the following:

• Hands-on experience with device communication protocols such as Bluetooth LE, Wi-Fi, or Thread
• Familiarity with embedded Linux environments or edge computing. The devices our app talks to run a Rust application on Linux hardware
• Experience with event-driven architectures or message brokers such as Kafka
• A track record of thriving in rapid-growth environments (start-ups, scale-ups, or new projects).

What is in it for you?

• Develop and grow in a fast-growing scale-up with a supportive and inclusive culture.
• Contribute to something measurable. Every smooth commissioning enables a more environmentally sustainable Europe.
• See your work in action in the real world. The app you build is used by technicians installing clean energy systems in people's homes across Europe every day.
• Collaborate with colleagues across the full value chain, from R&D in Sweden and manufacturing in Poland to installation teams on the ground in the UK, Germany, and Italy.
• Enjoy the flexibility of our hybrid work model, with our office centrally located in Stockholm near Sankt Eriksplan and Odenplan.

We interview on a rolling basis throughout the summer, with the majority of interviews taking place in August.

At Aira, we champion next-generation energy as well as diversity and inclusion. We firmly believe that a diverse workforce fosters innovation and creativity, enhancing our ability to serve customers and communities effectively, we welcome individuals from all backgrounds, cultures and perspectives to join our team. Our commitment is to uphold equality and inclusivity, fostering a collaborative environment where everyone can thrive and contribute to a better future for our people and the planet.
