## Job description

## 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 Development Manager to build and lead sales development at RunSybil. This is our first sales development leadership hire. You will take inventory of what is working today, translate it into an engine and build the team behind it.

This is a builder role first and a management role second. You will work with AEs, marketing and RevOps to design the outbound motion, from how we prospect and qualify to how we message and hand off to our account executives, and get it working before you start hiring. When you bring on SDRs, they will step into a function that already exists, with scripts and structure in place.

You will work closely with the founders and GTM leadership on strategy, and help us decide where agentic SDR tooling earns its place and where we are better off adding people. This is an early-stage role with a lot of ownership and plenty of room to shape how we sell. If you like to build, you are willing to do the unglamorous work yourself, and you are excited about AI, we want to hear from you.

## What You’ll Do

- Build a data-driven outbound motion end to end: prospecting, qualification, messaging, and the handoff that turns a cold prospect into a sales-ready conversation
- Personally run outbound before you hire, so the playbook is proven by the time the first SDR starts
- Stand up the tracking and reporting that make top-of-funnel activity and pipeline clear as the team grows
- Partner with the founders, Head of GTM, RevOps, Marketing and account executives on messaging, positioning, and a clean handoff into closing
- Hire, onboard, and coach the SDR team once the motion works, and build the ramp and structure that get new reps to quota
- Evaluate agentic SDR and prospecting tools, and decide where automation wins and where headcount makes more sense
- Own the top-of-funnel numbers, and carry what you learn in the field back to GTM and product

We're Looking For Someone Who Has A Mix of The Following

- Experience managing SDRs and/or inside sales reps, and a track record of building or rebuilding an outbound motion yourself
- A builder's instinct: you are comfortable doing the unglamorous work, and you will do it yourself before you have a team to hand it to
- Genuine excitement about AI and experience with AI automation
- Strength in creating process, with the ability to bring structure and accountability to a top of funnel that is growing fast
- Comfort operating without much direction, experience running experiments and data-driven decision making, ability to pivot and move quickly.
- Ease around technical, opinionated buyers and founders, and the ability to coach reps who interact with them
- Security, infrastructure, or developer-tools experience is a plus. Our buyers are technical security teams, so knowing that world helps

Location: (Remote - SF)

Compensation: Expected OTE for this position $180-$210,000. In addition to base salary, we offer meaningful equity. We want everyone here to have ownership in what we're building

Diverse teams build better products. RunSybil is committed to hiring people who bring different perspectives, lived experiences, and backgrounds to our work. We encourage candidates of all races, ethnicities, gender identity and expression, sexual orientation, disability or medical conditions, ages, religions, and socioeconomic backgrounds to apply. Pursuant to the San Francisco Fair Chance Ordinance, we will consider for employment qualified applicants with arrest and conviction records. If you're excited about this role but don't check every box, we still want to hear from you.

## About RunSybil

## Core Business
- **Primary industry**: Computer and Network Security / Offensive Security (AI-powered penetration testing)
- **Target customers**: Enterprise B2B – security teams at high-risk, multi-tenant, or rapidly deploying organizations
- **Mission**: “Automate hacker intuition” – replace periodic pentests and bug bounties with continuous, AI-driven validation of exploitable vulnerabilities.

## Products & Services
- **Sybil Platform**: An AI agent that continuously tests applications and infrastructure by reasoning like an elite human attacker. It chains vulnerabilities across code, APIs, cloud, and infra to surface only real, exploitable paths. Deployed on every deployment, it provides feedback on pull requests and enables Continuous Threat Exposure Management (CTEM) validation.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total funding – $40M (Seed round, March 2026)
- **Notable Investors/Partners**: Lead investor Khosla Ventures; 8 total investors in the seed round
- **Growth Signals**: Headcount grew 185.7% YoY to ~10 employees; monthly LinkedIn follower growth of +8.0% and yearly +285.8%; recent $40M raise signals strong investor confidence.

## Competitive Advantages
- **AI-native reasoning**: Sybil doesn't scan for signatures – it reasons like a human attacker, chaining multi-layer vulnerabilities and validating exploitability.
- **Continuous, context-aware testing**: Re-evaluates the attack surface on every deployment, adapting to changes rather than running periodic generic checks.
- **Reduced false positives**: Claims 90% fewer false positives by proving actual exploitability, eliminating triage burden.
- **Team pedigree**: Founders and early team hail from OpenAI, Meta, Mandiant, NCC Group, and Trail of Bits – combining frontier AI research with elite red-team experience.

## Strategic Focus
- Scaling the engineering and go-to-market teams to expand the platform’s coverage and customer adoption.
- Replacing traditional bug bounties and point-in-time pentests with continuous, AI-driven offensive security.
- Building a “company-survival mindset” and prioritizing velocity, shipping, and quality of thinking.

## Why Work Here
- **Culture**: “Built by researchers. Driven by conviction.” Emphasis on shipping fast, thinking like an attacker, preempting what’s next, and engineering craft.
- **Work model**: Hybrid with hubs in San Francisco and New York City; remote or hybrid options available.
- **Benefits**: Comprehensive medical/dental/vision (100% employee, 80–85% dependents), unlimited PTO (20-day suggested minimum), 12 weeks paid parental leave, 401(k) with 3% auto-enrollment, mental health and wellness support, commuter benefits, company-provided laptop, regular team onsites.
- **Team**: Small, high-caliber group (ex-OpenAI, Meta, Mandiant, NCC Group, Trail of Bits) working on the leading edge of AI and security. Interview process is structured, collaborative, and fast – LLM use encouraged.
