Backend Engineer - Acquisition

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:

We are looking for back-end engineers to join our product teams in Stockholm. Rather than hiring for one specific seat, we are

hiring for the group. We have several small, autonomous product teams working on the customer acquisition journey, each built

around four developers, a designer and a product manager, and we would rather find the right people first and work out the best

fit together.

The teams you could join:

Planning builds the tooling that schedules Aira's field force across the whole customer journey, from booking sales visits to heat

pump installations and maintenance. This is where the hardest optimisation problems live: travel times, route optimisation,

partial assignments, and mixing internal and subcontractor capacity as we scale into new regions.

Survey & Design owns the steps where we capture data about a customer's home and turn it into a tailored, carbon neutral energy

solution. The domain spans 3D modelling, thermodynamics, electronics and logistics. There is real modelling work here, along with

third party integrations that bring in geometric and climate data we have to transform into something our own model can use.

Expansion takes the product into new markets and improves how customers convert. New market launches, pricing, conversion flows,

solar PV output modelling, and the next generation of our heat pump product. Every new market brings its own rules, and the

backend is where most of that lands.

• Create feedback loops between the data we get from the thousands of installed heat pumps and our own tooling, making sure it

gets better over time

• Make sure our backend architecture scales gracefully with new product requirements and stays clean and approachable for both

your teammates and your future self

Our teams are not all set up the same way. Some have dedicated front-end and back-end engineers, others are full-stack across the

board. So there is a real home here for a backend specialist, and in the smaller teams there is always the possibility to dip your

toes in the web frontend or even our apps if you want to. We will be straight with you about which team is which.

Our tech stack includes Java (Spring Boot), gRPC, Postgres, Kafka, TypeScript, React, NextJS, tRPC, AWS, Kubernetes, Docker, and

Terraform.

Skills and mindset go hand in hand. If you don't meet every requirement but bring a positive and motivated attitude, we'd love to

hear from you!

• Gain hands-on experience in a fast-growing scale-up, with a supportive and inclusive culture, and career advancement

opportunities.

• Thrive in a dynamic, solution-oriented culture, tackling challenges and driving meaningful solutions that make a positive

impact on the world.

• Enjoy our brand-new office at Norra Stationsgatan 93 in Stockholm. Conveniently located near public transport, with Sankt

Eriksplan and Odenplan stations just a few minutes walk away.

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.
