About James McCarthy
I\'m a builder of teams, of strategies, and of lasting customer relationships. I\'ve spent my career helping some of the largest companies in the world solve complex security challenges, leading high-performing Sales Engineering teams, and closing transformational enterprise deals.As Director of Sales Engineering, Americas at Phosphorus, I\'ve scaled a global team, driven record-breaking revenue, and partnered directly with Product and Engineering to shape innovation that customers actually need. Along the way, I’ve helped land and expand partnerships with Fortune 10 leaders, major healthcare providers, and global enterprises.Outside of the deal cycle, I’m a frequent speaker at cybersecurity conferences, a co-host for corporate webinars and podcasts, and a big believer in using thought leadership to open doors and build trust. I also invest heavily in internal enablement, helping SEs and broader teams stay sharp, tell the right story, and move with confidence.At the core, I believe great Sales Engineering is about three things: earning trust, solving problems, and making complexity simple.
