C# Developer

We’re looking to strengthen our great product team with one or two sharp C# developers. If you consider yourself to be more of a full stack developer, then we’d also love to talk to you!

Sproom provides electronic invoicing services for ERPs, enterprises and integration partners in Denmark. Backed by Visma e-conomic, Sproom is uniquely positioned to grow even stronger and manifest our strong brand and services.

You and the Sproom product team will decide how to design and implement new functionality. We work on a C# stack with a SQL Server backend and we’re hosted on Azure and Google Cloud. We process more than half a million electronic documents per month and handle a couple of million requests on a daily basis.  

Our product team is distributed across Copenhagen, Krakow and Timișoara, but we meet physically a couple of times a year for work and fun. We pride ourselves on keeping our team cohesion and engagement top tier. We care about tech and about growing our skills. But above all; we care about each other and about how we grow as a team.


Is this you?

  • You’re a developer looking to gain and share knowledge

  • You care about delivering a solid experience to our customers

  • You're a team player who can also make independent decisions

  • You love to code and get a kick out of seeing your features in production


What does life at Visma look like?

We will offer you a competitive salary and benefits package. But, we hope you will give us a chance based on what truly makes us the coolest place to work (in our opinion):

  • We love that you bring your ideas to the table: You will be part of a culture that favors experiments and value initiative, so it’s easy to get your ideas heard.

  • Make an impact from day 1: We want you to experience meaning as much as you experience mastery through creating value that impacts people's everyday lives. And you get to influence how to go about creating that value with full autonomy of your work.

  • Flexibility at all stages of life: Work is an important part of life. Yet, we know that you are much more than your job. We make room for people at all stages of life.

  • We invest in your competence: When you step into Visma, opportunities from A-Z awaits. You will be met by engaged leaders that care for and support you, and take part in competence sharing and learning networks across Visma within.

  • Above all, we are a team: Team spirit is key for us to deliver on our promises to people and society, but most importantly; to form a culture where people support and care for each other as much as we have tons of fun together.
