Sales Engineer

About RunSybil

Founded in 2023 by Ari Herbert-Voss and Vlad Ionescu, RunSybil is on a mission to automate hacker intuition. We’re building Sybil: an AI-driven pentester that discovers vulnerabilities before they’re exploited. As adversaries adopt AI to increase their attack surface, we’re putting cutting-edge offensive security into the hands of defenders. Backed by strong investor support and early customer traction, our team is composed of experts from OpenAI, Meta, Mandiant, Palantir, Cruise, Trail of Bits, and Aptiv.

About the Role

We are looking for a Sales Engineer who owns the technical side of every deal. You will run demos, scope engagements, and be the person who makes sure a prospect fully understands what Sybil can do for their environment. You are equally comfortable in a discovery call with a CISO, a technical deep-dive with a red team, and a scoping conversation with a security engineer.

This role sits at the intersection of pre- and post-sales. You will stay close through onboarding and early delivery to make sure what you scoped is what we ship. At RunSybil, everyone's work is visible and every win is shared. You will have a direct hand in shaping how we bring Sybil to market and how our customers succeed.

What You Will Do

• Own the technical side of the sales cycle from first demo through close, working alongside the Account Executive on every deal
• Run pre-sales scoping calls to understand a prospect's environment, attack surface, and security program maturity, then translate that into a clear picture of where Sybil fits
• Work closely with Account Executives to build and deliver customer proposals, from initial scoping to presentation
• Deliver compelling, customized product demonstrations that speak to the specific concerns of technical buyers
• Lead engagement scoping for pilots and POCs, defining objectives, timelines, and success criteria in close collaboration with the customer
• Hold your own in technical conversations with security practitioners on findings, methodology, risk and offensive security topics
• Partner with Customer Success and Engineering during onboarding and early delivery to ensure customers get what was promised
• Surface patterns from the field back to product, including gaps in capability, messaging, and competitive positioning
• Build the SE function from scratch: demo environments, sales and scoping playbooks, technical objection handling, the works

What You Bring

• 8 or more years of B2B technical sales experience in cybersecurity, security services, or a complex technical product with long evaluation cycles
• Hands-on understanding of offensive security or application security with enough depth to earn credibility with practitioners
• Demonstrated ability to explain technical concepts clearly to different audiences, from security engineers to C-level executives, without losing nuance
• Experience running consultative discovery, scoping complex engagements, and managing technical evaluations with multiple stakeholders
• Comfort working across pre-sales and post-sales without treating the handoff as someone else's problem
• Strong organizational discipline to manage multiple active deals and POCs simultaneously
• Experience with CRM systems, preferably HubSpot, and sales tooling
• A builder's instinct: you figure things out rather than waiting for direction
