Join our team as a Senior Software Engineer!

Yes, you can! That's our attitude towards our work, ambitions, ideas, and relationships. We at Luminor believe that anyone has the potential to achieve big things and encourage everyone to achieve them, professionally and personally. 

Whoever you are and whatever your role is, with Luminor, you will get a once-in-a-lifetime opportunity to build a local banking champion.

As a Senior Software Engineer, you’ll take the lead in designing and building the bank’s core data systems-everything from ingestion and processing to storage and sharing. Your work will shape scalable, high-performance data architectures and robust ETL/ELT pipelines that keep information flowing reliably across the organization. You’ll collaborate closely with analysts, engineers, and business teams to deliver high-quality, secure, and well-monitored data solutions that support critical banking processes. Operating in a cross-functional Agile environment, you’ll drive technical improvements, solve complex challenges, and play a key role in advancing the bank’s data capabilities across the Pan-Baltic region.

• Experience with both SQL and NoSQL databases

• Exposure to test automation and DevOps practices, including infrastructure as code and security best practices

• Experience within the customer business domain is a strong advantage

• Ability to take ownership and drive initiatives independently
