  • Proficiency in C# and the .NET ecosystem (ASP.NET Web Forms or MVC/Razor)
  • Familiarity with CSHTML (Razor) templating and server-side rendering patterns
  • Competency in HTML, CSS, and JavaScript for front-end page work
  • Hands-on experience with Microsoft SQL Server (T-SQL)
  • Ability to write and optimize stored procedures, functions, and parameterized queries
  • Understanding of relational database design, indexing, and query performance
  • Working knowledge of SSRS - creating, modifying, and deploying reports
  • Basic familiarity with Power BI for data visualization and report development
  • Understanding of web application architecture and the request/response lifecycle
  • Comfortable using Git for version control and collaborative development
  • Strong attention to detail, especially when working with numerical/emissions data
  • U.S. citizen or legal right to work in the U.S.

Preferred Education and Competencies
  • Experience with GHG accounting concepts (Scope 1, 2, 3; biogenic vs. non-biogenic emissions)
  • Familiarity with XBRL or regulatory compliance reporting formats
  • Exposure to cloud hosting environments (AWS or Azure) and Windows Server administration
