We are looking for a Principal Engineer, Center of Excellence to join our Engineering Center of Excellence department. This is a remote U.S. based role, reporting to the VP of Customer Excellence within the Global Customer Services team.

You will work together with Support, Technical Account Managers, Engineering, QA, Operations, and Product Managers to increase technical proficiency across customer-facing teams and identify opportunities for greater efficiency. As one of a few top-level technical leaders, you will enable Global Customer Services (GCS) to deliver world-class support and product feedback.

What you’ll do (Role Expectations)

• Own the technical leadership to enable the customer teams across GCS
• Develop training material, with the aid of development engineering, to address trends in customer issues and engineer skill gaps
• Deliver technical training and/or train SMEs to lead training sessions
• Set strategy and direction for reflecting customer voice and product use cases back into the product teams
• Identify product supportability gaps and develop tools or features to improve troubleshooting efficiency

Who You Are (Success Profile)

• You thrive in ambiguity. You're comfortable building the path as you walk it. You thrive in a dynamic environment, seeing ambiguity not as a hindrance, but as the raw material to build something meaningful.
• You act like an owner. Your passion for the mission fuels your bias for action. You operate with integrity because you genuinely care about the outcome. True ownership involves leveraging dynamic range: the ability to navigate seamlessly between high-level strategy and hands-on execution.
• You are a problem-solver. You love running towards the challenges because you are laser-focused on finding the solution, knowing that solving the hard problems delivers the biggest impact.
• You are a high-trust collaborator. You are ambitious for the team, not just yourself. You embrace our challenge culture by giving and receiving ongoing feedback—knowing that candor delivered with clarity and respect is the truest form of teamwork and the fastest way to earn trust.
• You are a learner. You have a true growth mindset and are obsessed with your own development, actively seeking feedback to become a better partner and a stronger teammate. You love what you do and you do it with purpose.

• 8+ years of support and networking experience as an SME specializing primarily in SD-WAN and Cloud Connector Technologies
• Expertise in networking, cloud security, and performance management with the ability to quickly master new technologies
• Proven effectiveness at collaborating and building consensus across cross-functional teams and organizations
• Experience advising leadership at the Director level and above on technical strategy and voice of the customer
• Experience developing new processes, tools, or product features to improve troubleshooting efficiency
