Backend Developer (C# / .NET)

Salary Competitive

🚀 The Company 

Consensus is a Copenhagen-based technology company that develops and delivers innovative engagement solutions to international clients. 

At Consensus, we believe that engaged and well-informed employees are crucial to success, especially in a sector as vital as pharmaceuticals. Our SaaS platform, 'Connect,' isn't just software; it bridges the gap between a traditional Learning Management System (LMS) and a corporate communications tool to create a unified employee engagement experience that helps life sciences companies achieve their missions.


About the Role 

We are looking for a proactive and collaborative Backend Developer with deep expertise in C# and ASP.NET Core to join our dynamic team. This is an opportunity to see the direct impact of your work on a meaningful product and grow within a culture that values open dialogue, curiosity, and a shared commitment to quality.

You'll join a dedicated team of four developers, working closely with the business side of Consensus as our power users are in-house colleagues. This provides a unique chance to build features with a tight feedback loop and a strong focus on functionality.

This role is hybrid or on-site at our office in Østerbro, Copenhagen (not fully remote). 


About the team

The Development department consists of three agile teams, supported by dedicated product and design teams. We’re proud of our diverse backgrounds—our team includes a failed philosopher, a classically trained double bass player, an award-winning author, and an open-source maintainer. Experts like our Principal Frontend Engineer (a Microsoft MVP and GitHub Star) drive our culture of learning through regular guild sessions.


What you will do

  • Build & Innovate: Design, develop, and maintain our core backend services using C#, ASP.NET Core, and Entity Framework.

  • Tackle Complex Challenges: Take on challenges in scalability and real-time data synchronization for a platform serving major global clients.

  • Collaborate: Work within an agile team, participating in two-week sprints, code reviews, and shared documentation to ensure quality and adherence to best practices.

  • Partner with Business: Engage directly with our product team and other internal stakeholders to understand their needs, translate them into technical solutions, and enhance product functionality.

  • Enhance User Experience: Collaborate with our Product and UI/UX teams to ensure a seamless and intuitive user experience that meets the high standards of our clients.

  • Learn & Grow: Share your knowledge and contribute to our backend guild sessions, helping to elevate the entire team's skill set.


What You'll Bring

  • Extensive professional experience and deep knowledge of C# and ASP.NET Core.

  • Strong expertise in working with relational databases, like PostgreSQL.

  • A genuine enthusiasm for team collaboration and mentorship.

  • Excellent communication skills and an interest in understanding the business logic behind the code.

  • A proactive mindset and a drive to take initiative.

  • At least 2 years of professional software development experience.


Our Tech Stack

Keywords: C#, ASP.NET Core, Entity Framework, SignalR, PostgreSQL, Azure, Kubernetes, Git

Our backend is built on ASP.NET Core, using Entity Framework to interact with our PostgreSQL database and SignalR for real-time communication with our Angular-based frontend. The platform runs in Azure Kubernetes Service. You'll contribute to a monorepo codebase managed in GitLab.


Benefits & Perks

  • Flexible Work: A hybrid model that balances on-site collaboration with remote work.

  • Your Perfect Setup: Choose your own laptop, OS, and developer tools.

  • Great Office Life: Enjoy lunch at our office restaurant, Friday Bars, LAN Parties, Town Hall meetings, and biannual company summits.

  • Professional Development: We support your growth with opportunities for learning, attending conferences, and taking on new responsibilities.

  • Peace of Mind: We've got you covered with a paid phone plan, comprehensive medical insurance, and all the other important stuff.
