About this role
We’re seeking an experienced Software Engineer to maintain, enhance, and modernize a suite of .NET-based applications while developing new cross-platform, mobile, and distributed systems.

The role also includes transforming a legacy Windows application into a modernized, forward-compatible software architecture.
The ideal candidate is comfortable working across Microsoft and non-Microsoft stacks, private cloud environments, Linux-based microservices, modern front-end development, and mobile applications. Familiarity with AI-assisted development tools (Cursor, Copilot, etc.) is highly valued to improve both speed and quality.
