Identify risks and opportunities early, and create structured action plans to drive customer health, mitigate churn, and accelerate growth.

Advocate internally for your customers by partnering closely with Cortex Product, Engineering, and Sales teams, influencing product roadmap and strategy based on customer feedback.

Continuously raise the bar for how Cortex drives technical adoption, customer outcomes, and operational excellence.

Contribute to the evolution of our Customer Success motion — bringing ideas, feedback, and process improvements to help us scale a world-class CS organization.

Ability to converse fluently with technical users (engineering managers, SREs, platform teams) and speak to strategic outcomes with executives (VP Eng, CTOs).

Deep understanding of modern software development lifecycle (SDLC) practices, DevOps, cloud infrastructure (AWS, GCP, Azure), and internal platform models.
