Requirements Must have Current C# / .NET programming experience, with a strong understanding of programming concepts including algorithms, complexity, and multi-threading. Experience with SQL Server 2008 or newer as well as PostgreSQL, and comfort with SQL at a working-developer level: write queries, understanding how ORMs serialize and deserialize entities. You don't need to be a DBA or a data analyst. Experience building frontend features in Angular (solid React experience will substitute; willingness to work in Angular is expected either way). Experience building distributed, service-based applications — ideally with Kafka . Experience with a unit testing framework (NUnit, MS Test, or similar). Experience using Visual Studio, SSMS and git. Strong analytical and problem-solving skills, and the ability to debug across the stack. Open mind, curiosity, and a strong desire to learn new technologies and business domains. Ability to clearly explain non-trivial systems and algorithms. Ability to work efficiently in a fast-paced IT environment and do work with minimal supervision. Ability to maintain a 2+ hour daily overlap with US Eastern business hours (with a 6 hour overlap during the first two months of onboarding).
