Regional Sales Manager, Commercial

Horizon3.ai is a cybersecurity company focused on helping organizations find and fix their most critical security issues before attackers can exploit them. Our platform enables autonomous penetration testing and continuous security validation, giving security and IT teams a real attacker’s view of their environment so they can prioritize and remediate what matters most.

We are a fast-growing, product-led company built by security practitioners. We move quickly, iterate often, and prioritize impact. If you like seeing the direct results of your work and enjoy collaborating across functions to solve real customer problems, Horizon3.ai is a strong fit.

We are looking for a Regional Sales Manager to lead and grow our Commercial segment. You will manage a team of high-velocity sellers focused on commercial customers and be responsible for building pipelines, driving conversion, and delivering revenue.

You will report directly to the Director, Commercial Sales and align closely with her leadership style: collaborative, hands-on, data-aware, and very focused on coaching and development. This role is a mix of building and operating: you’ll be expected to refine the motion we have, create what doesn’t exist yet, and consistently raise the bar on performance in a way that is clear, fair, and supportive.

Horizon3.ai is in a period of rapid growth. Priorities will evolve, processes will mature, and we’ll learn as we go. The right person for this role understands that this comes with real work and occasional ambiguity, and is energized by the opportunity to help shape how the Commercial scales.

In this role, you will:

• →

• Demonstrated quota over-achievement as both an IC and a manager, with clear examples of targets and outcomes.

• Strong coaching and people-development skills:

  • You invest in helping people improve and grow.

  • You’re able to address performance issues in a way that is direct, fair, and focused on outcomes.

• Clear, confident communication and presentation skills, with the ability to engage both technical stakeholders and executive leadership.

• A data-informed approach to pipeline management, forecasting, and productivity, using numbers to support decisions rather than drive everything.

• High initiative and follow-through; you don’t need a fully built playbook to start making progress and you close the loop on what you commit to.

• Experience designing or refining outbound programs and campaign-based motions that drive net-new pipeline.

• Comfort working closely with the Director, Commercial Sales and acting as an extension of her leadership style, reinforcing shared standards and expectations within the Commercial pod.

• Genuine interest in cybersecurity and offensive security, and the ability to learn and explain technical concepts in straightforward language.

• Formal coaching or leadership training/certifications.

• Experience at a high-growth SaaS or cloud provider, especially in commercial segments.

• Experience building or significantly reshaping a sales function (process, playbooks, hiring profiles, metrics).

• Deeper exposure to offensive security, penetration testing platforms, red/purple teaming, or security automation.
