Senior Product Marketing Manager, WebApp

About the role

We are seeking a Senior Product Marketing Manager to lead the go-to-market engine for our newest, most explosive line of business: NodeZero WebApp Pentesting. You will be the entrepreneurial marketing lead for a massive expansion into the application security (AppSec) and Application Security Posture Management (ASPM) space. The market is currently being reshaped by AI hype, creating a distinct window of opportunity for a fierce competitor to seize total market ownership. You will report directly to the VP of Corporate & Product Marketing, partnering tightly with a world-class Product and Engineering team to turn deep technical capabilities into market dominance.

Responsibilities

• Go-To-Market Strategy & Launch Ownership
• Own the end-to-end GTM strategy, messaging, and positioning for the NodeZero WebApp Pentesting product line from its launch to market dominance.
• Architect an aggressive, pipeline-driven product launch framework that moves product marketing to a core revenue driver, not a corporate support function.
• Define target personas across Enterprise, Mid-Market, and Commercial segments, building a product narrative that maps directly to clear conversion paths.
• Competitive Positioning & Content Weaponization
• Drive the competitive narrative, explicitly dismantling legacy DAST incumbents and exposing fragile, unscalable "agentic AI" wrappers.
• Educate the market on why generic AI solutions suffer from exploding token costs, erratic inconsistency, and severe production risks, while positioning NodeZero's combination of a deterministic foundation and surgical AI as the only enterprise-grade choice.
• Develop proof-first product content, technical teardowns, and competitive battlecards that arm the sales force to win contested deals.
• Product & Engineering Collaboration
• Partner tightly with Product Leadership and Engineering teams, embedding yourself with the builders to transform highly complex offensive security capabilities into high-impact, market-facing narratives.
• Translate deep technical breakthroughs, e.g. the autonomous, production-safe exploitation of complex business-logic flaws like BOLA and IDOR, into clear, hype-free value propositions.
• Serve as the vital feedback loop between market realities, buyer pushback, and the product roadmap.
• Sales Enablement & Foundation Building
• Own the technical enablement motion for the direct sales force, SDRs, and channel partners including major VARs, resellers, and distribution partners.
• Win the hearts and minds of cynical, hype-hating developers, AppSec leads, and red teamers who demand zero false positives, while effortlessly elevating the message to the CISO/VP level to tell a broader platform and cyber-resilience story.
• Build the foundational processes, sales tools, and customer story pipelines required to scale this product line.

Requirements

• 5+ years (PMM) or 8+ years (Senior PMM) of B2B product marketing experience, with meaningful time spent launching and scaling complex technical products in a high-growth SaaS or cybersecurity company.
• Non-Negotiable Drive: High-agency, self-starting execution. You thrive in greenfield environments where processes don't exist yet, and you love the challenge of defining what "great" looks like from scratch.
• Deep Technical Chops: A background as a former security practitioner, pen tester, technical marketer, or technical PMM who has shipped AppSec, ASPM, or AI-driven security products. You must understand application architecture and the adversarial mindset far deeper than just cybersecurity acronyms.
• Dual-Altitude Communication: The rare ability to build deep trust with highly skeptical technical practitioners who demand absolute production safety, while seamlessly translating those technical truths into business resilience
