• Review technical designs and code, mentor engineers, establish reusable patterns, and raise engineering quality across the team
• Partner with architecture, cybersecurity, infrastructure, data engineering, analytics, AI, sourcing, and business teams to resolve cross-platform decisions and dependencies
• Drive measurable improvements in availability, MTTR, automation coverage, self-service adoption, resource utilization, and unit cost
• Ability to travel overnight.
• Represent Data & AI Foundation engineering in architecture, security, governance, audit, sourcing, infrastructure, and strategic planning forums
• Lead technology evaluations and build/buy/partner analysis for assigned platform capabilities, considering interoperability, security, operational complexity, vendor lock-in, and total cost of ownership
• Provide technical leadership without direct supervisory responsibility, coordinate work across engineers and partners, and perform additional duties as assigned
• Conduct all business in a professional and ethical manner
