Job Description Summary

The Specialist Software Engineer sets the technical direction for the design, development, and operational hardening of business-critical backend services built on C# and the .NET Framework. This role is the organization's authority on multi-threaded Windows Service design, service stability and recovery, and the diagnosis of complex production issues.

Responsibilities

Job Description

• Set the technical direction and lead the architecture, design, development, deployment, and operational support of business-critical Windows Services using C# and .NET Framework 4.8.
• Serve as the organization's subject-matter expert for multi-threaded application design, establishing patterns and resolving the most complex issues involving Monitor, volatile, Interlocked, ManualResetEvent, synchronization, and thread lifecycle management.
• Lead diagnosis and resolution of high-impact production issues involving concurrency, service stability, performance, memory usage, and resource contention; define systemic improvements that prevent recurrence. Drive issues to documented root cause rather than mitigation by restart.
• Design and establish self-managing service patterns: startup pre-flight validation before a service reports healthy, master-orchestration and worker-thread models, heartbeat monitoring and dead-thread recovery, failure thresholds with controlled escalation, and documented, visible blocked states in place of silent hangs.
• Define the transaction-integrity model for data entering our systems - received, persisted, then processed - with dead-letter handling and recoverable, replayable processing so that in-flight work is never lost.
• Provide technical authority for SQL Server design and performance, including execution-plan analysis, indexing strategies, isolation levels, concurrency, and deadlock prevention, detection, retry, and resolution. Establish connection-resil
