About the role and the Xomnia culture

In this role, you own delivery performance across multiple client accounts, overseeing multiple Data & AI projects.

You make sure projects within your portfolio are delivered on time, up to standard and within budget.

You know how to bring people together, build trust across teams, and create momentum. You work collaboratively with sales on proposals and of course with engineers, consultants, and clients to ensure delivery remains aligned, predictable, and impactful across the portfolio.
