Lead Customer Success Manager, EMEA

As a Lead Customer Success Manager at Corelight, you will own the customer success strategy for some of our most strategic and complex customers across EMEA. You will work with security leaders, SOC teams, and executive stakeholders to ensure customers realize measurable value from Corelight, deepen adoption, and build a strong foundation for long-term retention and growth.

This is a senior individual contributor role for someone who can operate comfortably across both the technical and executive sides of cybersecurity. You will understand each customer's security priorities, translate them into a clear success strategy, and coordinate the right resources across Corelight to deliver against it.

You will also help raise the bar for Customer Success more broadly by sharing best practices, mentoring teammates, and identifying opportunities to improve how we engage and deliver value to customers at scale.

• Build trusted relationships with customer stakeholders ranging from SOC practitioners and security leaders to CISOs and other executives.
• Develop a deep understanding of each customer's security environment, priorities, desired outcomes, and measures of success.
• Drive adoption and measurable value from Corelight's platform, connecting our capabilities to customers' broader security strategies and operational goals.
• Lead strategic customer engagements and Executive Business Reviews that demonstrate value, assess progress, surface risk, and align on priorities and next steps.
• Identify customer health, retention, and expansion opportunities early and partner closely with Sales and other teams to develop the appropriate account strategy.
• Lead complex customer escalations, coordinating across Support, Sales, Product, Engineering, and other teams to drive resolution while maintaining customer confidence.
• Represent the voice of the customer internally, identifying recurring needs and market trends that can inform product priorities and improve the customer experience.
• Mentor other Customer Success Managers and share approaches, tools, and best practices that strengthen the broader CS organization.
• Help develop scalable playbooks, processes, and programs that improve how Corelight delivers customer outcomes across EMEA and globally.
