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. We will talk about which team fits you best during the process, and you will meet the team before anything is decided. Some of the things you can expect to work with in this role: * Design and build backend services that scale to our users all over Europe * Create well designed APIs that stand the test of time * Integrate with third party providers reliably and transform their data into a data model that fits our use case * 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 What you bring to the team: * Have around 5+ years of experience as a Software Engineer * Feel comfortable writing Java code and using Spring Boot * Have a strong understanding of databases and domain driven design * Have experience building and documenting APIs * Can convert an idea into clean, testable, and scalable software services * Engage in team discussions and have a mindset to take responsibility * Have knowledge of microservices architecture 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. Nice to have: * Experience at fast-growing companies * Experience with gRPC and tRPC * Kafka or Kotlin * Writing front-end code in React * Experience with Kubernetes, Docker or Terraform 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! What is in it for you? * Gain hands-on experience in a fast-growing scale-up, with a supportive and inclusive culture, and career advancement opportunities. * Collaborate with diverse teams across international markets and launch products globally. * Develop and grow personally and professionally in an entrepreneurial-minded environment. * Thrive in a dynamic, solution-oriented culture, tackling challenges and driving meaningful solutions that make a positive impact on the world. * Influence the company's success, with a visible impact on product development and market growth. * Enjoy our brand-new office at Norra Stationsgatan 93 in Stockholm.
