Insurance Seattle, WA 201–500 employees Founded 1894 Privately Held

Grange Insurance operates across six Western states as a regional property and casualty insurer founded in 1894. The tech stack reveals an organization in active modernization: SQL Server and .NET Framework anchor legacy systems, while C# and .NET Core adoption signals a multi-year migration away from older infrastructure. Engineering hiring has accelerated (6 of 8 active roles in the last 30 days), concentrated in backend and platform teams, paired with parallel scaling in HR — a pattern that typically indicates either process bottlenecks or preparation for faster headcount growth tied to system rebuilds.
