Founding Product Marketing Manager

ABOUT CORRIDOR Software development is becoming autonomous. The fastest teams already work this way, and at Corridor, we are leading the way on secure development as the rest of the industry follows. Security tools were designed for a world where a person wrote the code and a person reviewed it. That's changing quickly. Corridor is securing software factories. We are the security solution for software that builds itself at every level of autonomy. We are preventing vulnerabilities as agents write code, and guiding teams to help decide what's safe to ship. Led by Jack Cable https://www.linkedin.com/in/jackcable/ (Former CISA - Secure by Design) and Ashwin Ramaswami https://www.linkedin.com/in/ashwin-r/ (Former CISA, Stanford, and Schmidt Futures). Corridor is backed by Conviction, with a $25M Series A led by Felicis and our customers include ElevenLabs, Lovable, Mercor, and Langchain. The Role We’re looking for a high-ownership Founding Product Marketing Manager to help define how Corridor goes to market as we build a new category in AI security. You’ll own our positioning, messaging, launches, and customer-facing narrative - working closely with customers and across Product, Engineering, Sales, and leadership to turn a complex technical product into something the market understands and wants to buy. What You’ll Do - Define how Corridor is positioned, understood, and differentiated as we build a new category in AI security. Turn complex technical concepts into clear, compelling stories for security, infrastructure, developer, and AI teams. - Own competitive intelligence across the AI security market - tracking competitors, product capabilities, and launches, and turning those insights into clear messaging, battlecards, and guidance for Sales and GTM teams. - Stay close to customers and prospects to understand their problems, language, buying decisions, and highest-value use cases. Bring those insights directly into Product, Sales, Marketing, and company strategy. - Create and ship the work that helps customers understand and buy Corridor — from website content and sales decks to case studies, messaging, launches, and other customer-facing assets. - Own the narrative, positioning, messaging, and go-to-market for new products and capabilities, working closely with Product, Engineering, Sales, and Customer Success. - Develop a deep understanding of the competitive landscape, legacy security approaches, and emerging alternatives. Turn that knowledge into sharp differentiation and a compelling customer story. - Test and iterate across positioning, messaging, launches, and demand generation. Use customer feedback and data to quickly double down on what works and cut what doesn’t. - Identify recurring customer problems, high-value use cases, and unmet needs and help shape what we build around the problems customers urgently need solved. Who You Are - A high-ownership PMM and builder who can go deep on a technical product and move quickly from strategic insight to execution. - You’ve been a first or early PMM, or held a similarly high-ownership GTM role at a high-growth startup. - You’ve marketed a technical product, ideally across AI, cybersecurity, developer tools, infrastructure, or a related space. - You have security domain experience or have marketed to security personas - You can earn credibility with technical buyers and engineers, while translating complexity into messaging that is simple, compelling, and commercially effective. - You’re equally comfortable talking to customers, developing strategy, writing copy, building a deck, shaping a launch, and shipping the work yourself. - You have exceptional writing and communication skills and know how to turn a complicated product into a story people understand and want to buy. - You’re deeply customer-obsessed and naturally look for the underlying problem, not just the feature or request. - You’re intellectually curious, opinionated, and willing to change your mind when the evidence says you should. - You thrive in ambiguity, move quickly without a playbook, and have a strong bias toward action, ownership, and measurable impact. - You have extensive experience in Product Marketing, GTM, Product, or a related role, with a track record of building positioning, messaging, ICPs, and GTM strategy from scratch. - You’ve personally created and shipped high-quality marketing and sales materials and worked closely with Product, Engineering, Sales, Customer Success, and leadership.
