Senior Episerver Web Developer

Apply your .NET skills as a developer within a multi-disciplinary A-team of experts. Day to day, you'll be collaboratively solving problems, architecting solutions, and expanding your mastery of CMS web development. If you are a tenacious problem-solver who thrives when digging deep into code and complex data sets, you will fit right in.

We specialize in the design and development of enterprise .NET websites, so experience working with a.NET content management system (Ektron, Episerver, Umbraco, Sitecore, etc.) is required.


When you become a .NET developer at Diagram, you'll get assigned to an account team with a strategist at the helm. Each team is responsible for working with a small group of clients, understanding their business goals, and building out a strategic roadmap to help push them forward. In your role, youcan expect a healthy mix of writing code, gathering requirements, participating in design critiques, architecting solutions,and coordinating with your team and clients. Each account team operates autonomously, meaning that the strategies your team propose will drive the work you do—what you can accomplish is limited only by your collective ideas and abilities.


The incredibly complex nature of the web projects we take on demand a wide range of technical prowess from our development leads. As a Diagram Web Developer, you'll need to demonstrate expertise in the following areas:

  • Programming Languages: C#

  • Microsoft Web Frameworks: ASP.NET, MVC, Razor, Web API

  • Database Solutions: SQL or TSQL

  • Strong understanding of core development concepts: Object-Oriented Programming (OOP),relational database concepts, Inversion of Control (IoC), and Dependency Injection (DI)

  • Integrating third-party solutions through Web Services or other messaging frameworks

  • Basic knowledge of IIS and setting up local sites

  • Using Git and version control

  • Familiarity with HTML, CSS, JavaScript, jQuery, and other JavaScript frameworks


Our organizational model involves building out small collaborative teams that kick ass. If you work best when you're handed a blueprint and left alone to build in solitude for weeks on end, you might not be a good fit. Diagram developers prefer to be in the mix of things and would rather contribute to solving real problems with code than to just take orders. You are naturally curious, eager to learn, and play nice with others. As a developer at Diagram, you are treated as a professional, working with other professionals for common goals.Day to day, some of your responsibilities will include:

  • Work with modern hosting technologies: Azure DevOps, CI/CD, AWS, Episerver DXC, Umbraco Cloud

  • Analyze, troubleshoot, and resolve issues on enterprise client websites

  • Adapt to and learn new and emerging .NET/CMS technologies

  • Communicate and convey technical concepts to clients, team members, and project managers

  • Contribute to functional requirements and technical documentation

  • Work both independently as well as collaboratively within a team

  • Propose and architect technical solutions that help drive our clients forward

  • Estimate effort for development tasks
