What the job involves

• We’re looking for a Principal Engineer to establish technical direction across Enterprise Applications and help teams turn that direction into reliable, incremental delivery. You’ll design systems, lead complex cross-team initiatives, influence engineering practices, and remain hands-on with implementation where your contribution has the greatest leverage
• You’ll model responsible AI-assisted engineering, operational excellence, sound judgment, and attention to detail
• Establish and communicate technical strategy across multiple teams, translating long-term direction into incremental delivery plans
• Lead complex, cross-functional initiatives from problem definition through architecture, implementation, deployment, and operation
• Influence technical decisions across teams through design reviews, prototypes, standards, mentoring, and hands-on contributions
• Build and extend AI-enabled systems, including agents, evaluation frameworks, MCP servers, and workflow automation
• Determine when AI is appropriate and when deterministic software offers a safer, simpler, or more reliable solution
• Establish practices for evaluating AI systems, including quality, reliability, security, cost, latency, and human oversight
• Improve engineering effectiveness through reusable platforms, operational tooling, automated diagnostics, and development workflows
• Partner with business and technical stakeholders to convert ambiguous problems into clear technical strategies and measurable outcomes
