Staff Software Engineer – .NET Windows Platform (On-Prem, MSSQL) hybrid

About the Role

This is a systems-focused self-hosted (on-premise) .NET role not a typical application-layer or cloud-first position.

Youll work on a foundational platform deployed in customer-managed environments where decisions span code database behavior and runtime/infrastructure characteristics.

This platform manages machine identitiescertificates keys and trust relationshipsinside enterprise environments where reliability performance and correctness are critical. The systems you build directly impact how organizations secure and operate sensitive infrastructure.

The platform is primarily built Framework and Windows-based systems so engineers in this role must be comfortable working in and maintaining Framework-based on-prem environments.

We welcome engineers from Core environments who are able to work beyond abstraction layers and adapt to system-level constraints.

If you care about how systems behave in production and want your decisions to directly impact performance reliability and long-term system design this role will be a strong fit.

What Youll Do

• Own system behavior across application database and runtime layers in self-hosted environments
• Diagnose and resolve issues such as slow SQL queries resource contention and performance bottlenecks
• Design and optimize data access patterns and database performance (beyond ORM abstraction)
• Build for real-world deployment environments (Windows services on-prem systems long-lived installations)
• Lead technical discussions and walk through code system behavior and tradeoffs in real time
• Mentor engineers and elevate system-level thinking across the team
• Use AI-assisted development tools to improve efficiency while maintaining deep understanding and production-quality standards

• Experience building systems deployed in self-hosted or customer-managed environments
• Experience working in systems where infrastructure deployment model and runtime behavior influence design
• Ability to clearly explain and reason through technical concepts in real time

Why This Role

• Work on a foundational platform in a security-critical domain
