Senior Sales Engineer (Pre-Sales)

Customer Success Hybrid (Remote / On-Site) Opening Senior Sales Engineer is a pre-sales, customer-facing role working closely with the Sales team. You'll spend your days in discovery calls, demos, POVs, and deal strategy — not in a NOC or writing production code, but you will also participate in post-sales technical escalation support on occasion, as well as collaborate with customer success and customer onboarding requests. This is not a software or network architect role.” Pre-sales Engineering experience is required. About ZeroTier ZeroTier leads the world in next-generation connectivity and cybersecurity.

You own the technical win: discovery, solution architecture, demos, and proof-of-value engagements end-to-end, then hand off cleanly to Customer Success.
