SalesSales Engineer

Senior Sales Engineer is a pre-sales customer facing,quota-adjacent role on the Sales team. You'll spend your days in discovery calls, demos, POVs, and deal strategy — not in a NOC nor writing production code but will also participate in post sales technical escalation support on occasion as well as collaboration with customer success and customer onboarding requests.”This is not a software or network architect role.” Pre-sales Engineering experience is required.

ZeroTier 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.

You are the technical counterpart to our Account Executives and the trusted advisor to buyers — 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, CNSA 2.0-compliant 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.

Requirements

~1 min read

Strong networking fundamentals: Layer 2 vs. Layer 3 behavior, routing, NAT and NAT traversal, firewalls, DNS, and overlay/underlay separation.

Comfort at the packet level — Wireshark/tcpdump is a working tool, not a party trick.

Solid Linux and real cloud experience (AWS/Azure/GCP): VPCs, routing, security groups, hybrid connectivity.

Hands-on familiarity with at least two of: SD-WAN, ZTNA, VPN technologies (WireGuard, IPsec, OpenVPN), container networking, or embedded/IoT connectivity.

Working knowledge of SSO/identity (OIDC, SAML, Entra ID/Okta) as it intersects with network access.

Scripting fluency (Python, Bash) — enough to automate a demo environment and exercise a REST API.

The ability to translate all of the above into plain-language business value for a non-cryptographer audiences

Selling into defense, government, or regulated sectors (DOD, GovCloud, sovereign infrastructure).

Background in OT/industrial environments (Modbus, IEC-61850, SCADA).

Prior work at an overlay networking, mesh VPN, ZTNA, or SD-WAN vendor.

Experience as a first or early SE hire — building the function, not just running plays.

A working grasp of modern cryptography and the quantum threat model — why "harvest now, decrypt later" makes PQC a today problem — and familiarity with the NIST PQC standards (FIPS 203/204/205), hybrid schemes, and the CNSA 2.0 compliance landscape. Most importantly: the ability to translate this into plain-language business value without overselling.

Familiarity with the NIST post-quantum standards (FIPS 203 / ML-KEM, FIPS 204 / ML-DSA, FIPS 205 / SLH-DSA), hybrid classical + PQC schemes, and crypto-agility as an architectural principle.

Awareness of the compliance landscape driving adoption: CNSA 2.0 timelines, FIPS 140-3 validation, and PQC mandates emerging across government and regulated industries.

You'll report to the Director of Pre-Sales Engineering & Customer Success and partner daily with Sales, Engineering, and Customer Success. Remote-first with occasional travel for key customer engagements, POV kickoffs, and industry events. We move quickly, write things down, and hold a high bar for what we put in front of customers.

Competitive salary + variable compensation tied to team success and available equity

Hybrid office / remote work environment

Generous employer-paid health insurance, including preventative dental

401K with employer matching

Flexible PTO and flexible work hours
