As a Principal Software Engineering Manager, focuses on people leadership, technical direction, and delivery outcomes across teams.

In this role, you are expected to:

• Lead, coach, and support a team of Software Engineers by providing clear expectations, regular feedback, and career guidance through one-on-one connections, mentoring, and performance discussions.
• Set and align technical direction and execution plans by partnering with Product Managers and cross-functional stakeholders to translate customer needs and business priorities into engineering plans.
• Support operational excellence and delivery consistency by reinforcing engineering fundamentals, planning practices, and coordinated response to incidents and live-site issues.

• Leverage customer feedback, telemetry, and product usage data to identify improvement opportunities, prioritize investments, and guide teams toward long-term Windows Fundamentals enhancements.

• Establish and reinforce engineering practices for design reviews, code reviews, testing, and continuous integration to support secure, maintainable, and scalable solutions.
• Provide technical guidance and escalation support by working with engineers on complex diagnostics using debugging tools, performance analysis, and code-level investigation, and representing the team in cross-organization discussions.
• Foster a customer-focused and inclusive team environment where engineers understand customer impact, collaborate across teams, and take shared ownership of outcomes that matter to customers.

AI‑Forward Engineering

• Champion AI‑assisted and agentic engineering workflows across the org; set standards and expectations so teams use AI to move faster without compromising security or quality.
• Establish guardrails and best practices for responsible use of AI tools—ensuring correctness, security, privacy, and compliance.
