• Lead root-cause analysis (RCA) across application, API, and database layers.
• Design and implement maintainable, scalable, and testable solutions for defect resolution and system improvements.
• Originate and institutionalize best practices, standards, and methodologies that improve engineering effectiveness and platform reliability.
• Balance short-term fixes with long-term architectural integrity and maintainability.

Complex Problem Solving & Systems Optimization

• Solve highly complex, cross-domain problems using advanced technical knowledge and broad experience.
• Diagnose and optimize system performance across frontend, backend, and database layers.
• Analyze Oracle database performance, including SQL optimization and execution plan tuning.
• Lead technical debt reduction initiatives, prioritizing work that delivers meaningful improvements to system health and developer productivity.
• Introduce new tools, approaches, or patterns that elevate operational efficiency and platform resilience.

Software Development & Quality

• Develop and maintain solutions in TypeScript/React and C#/.NET Core services.
• Write and maintain automated unit and integration tests to reduce defects and prevent regression.
• Refactor legacy code to improve clarity, maintainability, and performance.
• Ensure adherence to secure coding practices and enterprise standards.
• Collaboration & Influence
• Build strong relationships and influence stakeholders across engineering, product, and operations through clear communication of complex concepts.
• Translate deep technical issues into actionable insights for cross-functional partners.
• Provide mentorship and guidance to engineers, actively developing team capabilities and avoiding common pitfalls.
• Contribute to a culture of continuous improvement, intellectual humility, and engineering excellence.

Operational Excellence

• Own incoming operational requests during business hours and drive timely resolution.
• Create and maintain runbooks, documentation, and training materials to improve response consistency and reduce operational friction.
• Collaborate closely with Operations, Product, and other stakeholders to ensure issues are properly prioritized and understood within business context.
• Utilize observability tools (e.g., Application Insights, Datadog) to proactively monitor and improve system performance.

AI & Automation Responsibilities

• Leverage AI-assisted tools and agents to accelerate triage, debugging, and root-cause analysis workflows.
• Design, build, and maintain AI-enabled developer tooling (e.g., MCP servers, diagnostics automation) to improve team productivity.
• Establish responsible AI usage practices, ensuring outputs are validated, explainable, and aligned with engineering standards.

Education & Experience:

• Bachelor’s degree in Computer Science or related field.
• 5+ years of experience in enterprise software engineering.
• Strong experience with C#/.NET Core and TypeScript with modern frameworks (React preferred).
• Deep expertise in Oracle databases, SQL, and PL/SQL, including performance tuning and execution plan analysis.
• Proven experience handling complex production issues and driving RCA to resolution.
• Experience with distributed systems, APIs (REST/GraphQL), and microservices architectures.
• Advanced understanding of system design, data modeling, and performance optimization.
• Experience with automated testing frameworks and TDD practices.
