Senior Sales Engineer (Pre-Sales)

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 Zero. Tier Zero. Tier leads the world in next-generation connectivity and cybersecurity. Our platform provides highly secure, peer-to-peer virtual networks relied upon by millions of users and businesses - from individual users and startups to mid-scale enterprises and Fortune 500 companies.

We’re backed by awesome investors including Battery Ventures, Bonfire Ventures, and Anorak Ventures. The Role You are the technical counterpart to our Account Executives and the trusted advisor to buyers across Europe, Africa, Asia, and other parts of the world — from a founder connecting a fleet of Raspberry Pis, to an industrial OT team bridging PLCs across plants, to a defense integrator architecting an air-gapped, post-quantum secure sovereign network.

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