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
This is a senior individual-contributor role reporting to the Director of Product Marketing. You will be the close go-to-market counterpart to the Senior Product Manager for Platform and a day-to-day partner to the Senior Alliances Marketing Manager. Together with Product, Engineering, Alliances, Sales, Solutions Engineering, Customer Success, and technology alliance partners, you will make complex integrations, APIs, MCP, and developer experiences clear, credible, and commercially compelling.
The market problem you will help solve is bigger than a catalog of connectors: valuable security intelligence is often trapped in a portal, copied into tickets by hand, or disconnected from the workflows where teams act. You will help Horizon3 win by showing how NodeZero can embed into the customer’s existing security stack and contribute to a connected Hack, Fix, Verify loop.
Product Management will own product vision, requirements, roadmap, prioritization, scope, and technical trade-offs. You will own how the value is positioned, launched, activated, adopted, sold, and proven in the market.
Own the platform integrations narrative
Build and evolve the positioning and messaging for NodeZero’s integrations, APIs, MCP, and integration framework.
Explain the customer value of putting proven exploitability intelligence into SIEM, SOAR, ITSM, EDR/XDR, vulnerability-management, and other security workflows.
Create a coherent platform story that connects native integrations, partner-built experiences, developer access, and agent connectivity without reducing the message to “we integrate with X.”
Develop audience- and use-case-specific narratives for security executives, security operations and vulnerability-management leaders, technical champions, developers, partners, and field teams.
Clarify the difference between NodeZero’s high-signal, attacker-validated intelligence and generic telemetry, vulnerability volume, or disconnected point-tool workflows.
Partner with Product and Engineering as the GTM counterpart
Operate as part of the product trio with the Senior Product Manager for Platform and Engineering leadership, bringing market, customer, field, and partner evidence into product discussions.
Translate product direction, release state, and technical capabilities into accurate external promises, compelling use cases, and actionable launch plans.
Stay close to product details, integration behavior, API and MCP experiences, developer readiness, and customer workflows so the market story remains technically credible.
Partner on launch timing and readiness while preserving the ownership boundary between product decisions and go-to-market decisions.
Help identify adoption friction, messaging gaps, and unmet customer or partner needs that should inform future product iterations.
Lead joint go-to-market with Technology Alliances
Work closely with the Senior Alliances Marketing Manager and technology alliance partners to turn selected integrations into coordinated launches and sustained GTM programs.
Develop partner value propositions, joint solution narratives, customer use cases, launch briefs, co-marketing plans, marketplace and listing inputs, and joint selling motions.
Coordinate partner-facing marketing work across Horizon3 and partner stakeholders without assuming ownership of partnership agreements, commercial terms, or relationship governance.
Create “better together” stories that demonstrate how NodeZero and a partner help customers act on proven exploitability in the systems they already use.
Build reusable alliance and integration marketing motions that make partner activation more consistent and scalable.
Drive launch readiness, field activation, and adoption
Orchestrate launches across Product, Engineering, Alliances, Sales, Solutions Engineering, Customer Success, Demand Generation, Communications, and partner teams.
Equip internal and external audiences with messaging, demo flows, talk tracks, FAQs, competitive framing, solution briefs, technical explainers, customer-facing content, and enablement modules.
Support readiness across early access, general availability, and follow-on iterations—not only announcement day.
Partner with Sales and Customer Success to connect integration capabilities to customer outcomes, adoption paths, expansion opportunities, and time-to-value.
Capture field and customer feedback after launch and turn it into practical improvements to positioning, enablement, adoption programs, and future GTM plans.
Build evidence and measurement into the motion
Define and track measures that reflect workflow value and commercial impact, not connector count or press-release volume alone.
Establish visibility into customer usage, shared-customer activation, adoption and engagement, integration-influenced pipeline, partner-sourced or partner-influenced opportunities, launch performance, and the reach of NodeZero through integrations, APIs, and MCP.
Partner with Product, Sales Operations, Customer Success, and Alliances to create a practical measurement approach and use the evidence to improve priorities and programs.
Develop customer proof points, references, and use cases that show how platform connectivity changes security-team behavior and outcomes.
Create leverage through repeatable systems
Build reusable integration and partner-launch briefs, messaging frameworks, launch checklists, enablement modules, customer-proof templates, and measurement plans.
Establish a clear operating rhythm for launch planning, partner coordination, readiness reviews, feedback capture, and post-launch learning.
Improve the quality and speed of GTM execution so each new integration does not require inventing a marketing motion from scratch.
Stay close enough to actual deals, losses, customer conversations, and partner feedback to ensure the system improves from real evidence.
What Success Looks Like in Your First 6–12 Months
A clear, differentiated platform integrations narrative is used consistently across the website, sales conversations, partner materials, launches, and executive communications.
Priority integrations and platform capabilities have coordinated GTM plans, accurate positioning, launch-readiness materials, field enablement, and post-launch adoption follow-through.
The Product, Alliances, and Marketing teams share a repeatable operating model for turning integration work into joint launches, customer proof, and measurable business impact.
Sales, Solutions Engineering, Customer Success, and partner teams can confidently explain, demonstrate, position, and activate the relevant integration and API/MCP use cases.

Customer, field, and partner evidence is consistently fed back into Product and Engineering discussions to improve the next iteration.
Reusable GTM systems reduce the effort required to launch and scale additional integrations and technology-alliance motions.
