Regional insurance provider with auto, home, life, and commercial coverage

Insurance Columbus, OH 1,001–5,000 employees Founded 1935 Privately Held

Grange Insurance operates a multi-line regional insurance business across 13 states, backed by a 1,000+ person workforce and an A.M. Best rating of A (Excellent). The tech stack reveals an incumbent-facing modernization effort: Java and Guidewire (core insurance platform) paired with cloud adoption (AWS, Azure), ELK-stack observability tooling, and early-stage AI initiatives—while legacy infrastructure modernization and system visibility remain listed pain points. Active hiring skews toward internship and mid-level roles in claims, operations, and data, suggesting a scaling organization rather than a senior leadership overhaul.
