Senior Federal Account Executive, DoD

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. Node Zero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises.

It is used by ITOps/Sec Ops 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.

We are seeking a Senior Federal Account Executive, Department of Defense to own and grow a named portfolio of defense customers across the military departments, defense agencies, combatant commands, and program executive offices. This is a quota-carrying, individual contributor role responsible for the full sales cycle: mission discovery, sponsor and requirement development, proof of value, authorization and contract path, close, and program expansion.

Selling autonomous pentesting into defense is not a commercial motion run in a different building. The buying center is a program or mission owner, the technical gate is an authorization decision, and the contract path is frequently a vehicle, an OTA, a consortium, or a prime rather than a direct purchase order. Our CEO is a former CTO at U.S. Joint Special Operations Command, Node Zero is the offensive security engine behind the NSA Cybersecurity Collaboration Center's Continuous Autonomous Penetration Testing program, and the platform is assessed "Awardable" in the Department of War's Platform One Solutions Marketplace and listed on the Tradewinds Solutions Marketplace.

You will be selling into a market where we already have mission credibility and access routes, and where the work is converting that credibility into programs of record.

The ideal candidate has carried and exceeded a multi-million dollar DoD quota, is fluent in how defense organizations actually buy, and can hold a technical conversation about attack paths and mission risk with an operator without needing an SE in the room. You will own your portfolio as a business: named account and program plans, sponsor and authorizing-official maps, a partner and prime strategy, and a forecast you can defend line by line.

This role will be responsible for:

• Own a named portfolio of DoD/DoW customers spanning military departments, defense agencies, combatant commands, program executive offices, and joint and mission-focused cyber organizations, carrying an annual net-new ARR quota with defined expansion targets.

• Build program-level account plans that identify the mission system, the accountable mission or program owner, the funding line, the authorization path, and the contract vehicle before forecasting revenue against them.

• Prospect and self-source pipeline into program offices, service and agency CIO/CISO organizations, cyber protection and defensive cyber operations teams, SOC and vulnerability management functions, RMF and authorization staff, and mission owners.

• Qualify against defense buying reality — active mission need, named sponsor, identified funding, viable authorization path, and executable contract route — and disqualify early and explicitly when those conditions are absent.

• Pursue program-led and enterprise-scale opportunities where a single contract action reaches many end users, systems, or suppliers, rather than optimizing for individual seat-based transactions.

• Run proof of value and paid…
