● Serve as a senior technical leader and trusted advisor across engineering, product, support,
implementation, and executive leadership.
● Guide internal engineers and external development partners on architecture, coding standards,
design patterns, and technical best practices.
● Conduct code reviews, mentor developers, and help establish engineering practices for quality,
testing, performance, and maintainability.
● Act as a technical escalation point for complex application, integration, infrastructure, and production issues.
● Partner closely with ISI leadership to ensure engineering execution aligns with business priorities,
customer commitments, and long-term product strategy.
