Staff Software Engineer – .NET / Windows Platform (On-Prem, MSSQL) - hybrid
About The Position
This is a systems-focused, self-hosted (on-premise) .NET role, not a typical application-layer or cloud-first position. You’ll work on a foundational platform deployed in customer-managed environments, where decisions span code, database behavior, and runtime/infrastructure characteristics. This platform manages machine identities—certificates, keys, and trust relationships—inside 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 on .NET 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 modern .NET 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.
Requirements
- Strong .NET experience (Framework and/or .NET Core)
- Deep C# fundamentals, including:
- object lifecycle and dependency injection
- threading and concurrency
- memory behavior
- async/await execution
- Strong MSSQL experience (query tuning, execution plans, indexing, diagnosing slow queries)
- Ability to understand and optimize database behavior directly, not rely solely on ORM abstraction (e.g., Entity Framework)
- 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
Responsibilities
- 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
Benefits
- The compensation package includes a wide range of medical, dental, vision, financial, and other benefits.
