Evaluate and introduce new technologies, tools, practices, and process improvements to improve scalability, reliability, and developer productivity and efficiency. Identify and mitigate technical risk across initiatives. Analyze and debug issues. Champion utilization of AI tools (e.g., code assistants, code search, test generators, doc summarizers, static analyzers with AI) to accelerate building, coding, testing, and fixing issues. Establish guidelines/guardrails for AI-assisted code contributions (prompt patterns, review standards, security/compliance). Use AI to mine logs, triage incidents, and propose fixes; generate/maintain architecture docs and ADRs. Evaluate and integrate AI-enabled tooling into the SDLC. What We're Looking For Bachelor's degree in Computer Science or related field (or equivalent experience). Technical expert in C# and the .NET ecosystem. 10+ years of commercial software engineering experience, including significant experience designing and delivering large-scale libraries, frameworks, platforms, and/or multi-threaded applications. Demonstrated ability to design and architect new initiatives independently. Deep expertise in multi-threading, eventing, inter-process communication, concurrency, performance tuning, and memory management. Demonstrated proficiency in object-oriented building, architectural patterns, and principles passionate about business logic and structure. Proven experience leading technical implementation across teams. Strong understanding of secure system design, networking, encryption, and hardware/software integration. Experience leading cross-team technical initiatives and influencing engineering standards across an organization. Exceptional analytical, debugging, and root-cause analysis skills. Demonstrated ability to mentor senior engineers and elevate interpersonal technical capability. Demonstrated ability to investigate and evaluate new technologies based on both technical and business needs. Track record of promoting a culture of quality, accountability, and technical integrity.
