We are looking for a Software Developer to join our microservices team and help us build reliable, scalable systems. In this role, you will design and develop services that support real-time, event-driven architectures and long-term maintainability. You will work closely with business stakeholders and other Software Developers in a hands-on, practical setup.
If you speak Estonian, you can also get a deeper look into what our microservices team is building and meet two of our team members in this podcast.
What you will work on
- Designing, developing and maintaining services built on Java (17+) and Spring Boot, with a strong focus on clean architecture, reliability and scalability.
- Building and evolving event-driven, microservices-based systems, including real-time data processing and stateful services that react to asynchronous events.
- Developing solutions that behave predictably under load and in production environments.
- Collaborating across teams to integrate services with other systems.
What describes you
- You have a solid technical foundation and are comfortable working across the software development lifecycle.
- You have hands-on experience with Java (17+) and Spring Boot, and have built event-driven systems that work with real-time data.
- You are confident in designing and developing REST APIs and working with SQL-based data stores.
- You are fluent in English.
- You have a genuine interest in renewable energy and are eager to use innovation and AI in your work.
What we offer
- Support for your wellbeing, inside and outside work - a quarterly sports allowance via Stebby, comprehensive employer-provided health insurance (including dental care and specialist visits), and access to mental health counselling and coaching via siffi.com.
- Time to rest and reset - 28 working days of annual leave, counted only in working days and usable flexibly, plus additional paid days off, including health days and leave for important life events.
- Room to grow professionally - meaningful, hands-on challenges and a dedicated training budget for courses, certifications, and conferences, alongside internal learning opportunities to support your development.
- Flexible hybrid work - we work in a hybrid way, with no fixed rules on office days. You are trusted to balance remote work with time in the office, and while much can be done remotely, a lot happens in the office and being there regularly makes collaboration easier.
- Work that contributes to the energy transition - you will be part of a team building and scaling renewable energy across the region, working on services that support a more sustainable energy system.
If you are excited about contributing to the renewable energy sector, we would love to hear from you! We review applications on an ongoing basis, so we encourage you to apply as soon as possible.
