Onboarding Program Manager, GTM

Get to Know Us
Horizon3 is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find and fix and verify exploitable attack vectors before criminals exploit them. Our flagship product, the NodeZeroTM platform, delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments. NodeZero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises. It is used by ITOps/SecOps teams, consulting pentesters, and MSSPs and MSPs.

We are a fusion of former U.S. Special Operations cyber operators, startup engineers, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools, false positives resulting in alert fatigue, blind spots, "checkbox” security culture, cybersecurity skills shortage, and the long lead time and expense of hiring outside consultants. Collectively, we are a team of learn it alls, committed to a culture of respect, collaboration, ownership, and results.

What You’ll Do
Horizon3 is scaling its go-to-market organization across segments, roles, and regions. We believe a consistent, role-relevant onboarding and ramp experience is one of the most important levers for accelerating productivity, reinforcing how we sell, and creating consistency as we grow.

We are looking for a
GTM Onboarding Program Manager
to own and scale the end-to-end onboarding and ramp experience for our GTM organization. This includes onboarding quota carriers across Commercial, Mid-Enterprise, and Enterprise sales, as well as SDRs and, over time, extending the program to Sales Engineers, Customer Success, and other customer-facing teams.

Reporting to our Field Enablement and Global Onboarding Leader, you will design and operationalize repeatable onboarding journeys from pre-boarding through readiness and the first 90 days in role. The monthly GTM sales bootcamp is a key component of that experience, bringing new hires together for immersive learning, connection, and certification, but this role is responsible for the broader system that surrounds bootcamp, including role-based learning paths, manager reinforcement, post-bootcamp ramp, and measurement of time to productivity.

You will partner closely with GTM Enablement, Sales leadership, Product Marketing, RevOps, People, managers, and subject matter experts to ensure each audience develops the context, skills, behaviors, and role-specific capabilities needed to contribute quickly. As Horizon3 grows, you will build the processes, infrastructure, and operating rhythm that allow onboarding and ramp programs to scale efficiently while maintaining a high-quality employee experience.

This role will be responsible for

• Owning the end-to-end GTM onboarding and ramp program from pre-boarding through the first 90 days, including role-specific readiness milestones and manager reinforcement.
• Designing and continuously improving onboarding paths for Commercial, Min-Enterprise, and Enterprise sellers, SDRs, and, over time, Sales Engineers, Customer Success, and other customer-facing teams.
• Owning and evolving the monthly GTM sales bootcamp as a central component of the broader onboarding experience, including curriculum, certification, facilitation, logistics, onsite execution, and post-program follow-up.
• Connecting pre-work, bootcamp, role onboarding, manager-led reinforcement, field application, and post-bootcamp ramp into one cohesive experience.
• Establishing clear learning objectives, role expectations, certifications, readiness checkpoints, and success measures for each audience.
• Equipping managers with practical reinforcement plans, coaching resources, and visibility into what new hires have learned and what they need to apply on the job.
• Partnering with Sales, RevOps, Product Marketing, Enablement, People, and subject matter experts to keep onboarding aligned to business priorities, product changes, sales methodology, segment needs, and observed skill gaps.
• Creating and maintaining participant guides, learning materials, resource hubs, facilitator plans, communications, and repeatable playbooks.
• Measuring onboarding effectiveness through certification, readiness, manager feedback, new-hire feedback, ramp performance, time to productivity, and other business outcomes.
• Using quantitative and qualitative data to identify where new hires are succeeding, where they are struggling, and where the onboarding experience needs to improve.
• Building scalable systems for cohort planning, communications, registration, scheduling, completion tracking, reporting, and program operations.
• Managing the participant and event experience for bootcamp and other onboarding programs, including speakers, travel, lodging, meals, venues, vendors, and onsite logistics.
• Creating a consistent, high-quality onboarding experience while adapting the content and support model to the needs of different roles, segments, and regions.

What You’ll Bring

• 5+ years of experience in sales enablement, onboarding facilitation, learning and development, program management, event/program operations, or a related field.
• Experience owning recurring, multi-day onboarding, bootcamp, academy, training, or enablement programs from planning through onsite execution.
• Exceptional program management skills with the ability to manage multiple work streams, stakeholders, vendors, timelines, dependencies, and deadlines simultaneously.
• Strong operational and logistical skills with experience coordinating travel, hotels, venues, catering, events, speakers, communications, calendars, and onsite experiences.
• Comfort being highly hands-on—you are equally willing to build the program plan, coordinate an executive speaker, troubleshoot a hotel issue, and make sure the room is ready before the first session starts.
• Strong attention to detail and the ability to anticipate what could go wrong before it becomes an issue.
• Experience supporting a high-growth B2B sales or GTM organization; cybersecurity, SaaS, or technical product experience is preferred.
• Understanding of how GTM roles such as SDRs, AEs, SEs, Customer Success, and sales managers operate and how their onboarding needs differ.
• Ability to turn complex business, product, and sales concepts into clear and practical learning experiences.
• Strong facilitation and communication skills and comfort engaging with both new hires and senior leaders.
• Experience partnering with executives, senior leaders, and subject matter experts to develop and deliver programming
• Ability to create structure, repeatability, and clear ownership in a fast-moving environment
• A learner-first and experience-focused mindset combined with a strong focus on business outcomes and speed to productivity.
• Comfort using data and feedback to assess program effectiveness and make changes quickly.
• Excellent written and verbal communication skills.
• Ability to operate independently, make sound decisions, and move programs forward even when every detail has not yet been defined.
• Experience with LMS, enablement, sales productivity, event management, or learning technology platforms is a plus.
• Experience building programs across multiple geographic regions or distributed teams is a plus.
