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. We're a small, talented team, led by Jack Cable (Former CISA - Secure by Design), Ashwin Ramaswami (Former CISA, Stanford, and Schmidt Futures) and, Alex Stamos (Former CISO of Facebook, Yahoo, SentinelOne). 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 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 Own Corridor’s positioning and narrative: Define how Corridor is understood, positioned, 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. Turn customer insight into GTM: 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. Build and ship GTM: Create the materials that help customers understand and buy Corridor, including website content, sales decks, case studies, messaging, product launches, and other customer-facing assets. Own product launches: Develop the narrative, positioning, messaging, and supporting materials for new products and capabilities, working closely with Product, Engineering, Sales, and Customer Success. Differentiate Corridor: Develop a deep understanding of the competitive landscape, legacy security approaches, and emerging alternatives—and translate that into clear differentiation and compelling customer value. Test and iterate: Run experiments across positioning, messaging, launches, and demand generation. Use customer feedback and data to quickly understand what resonates and improve what doesn’t. Help shape what we build: Identify recurring customer problems, wedge use cases, and unmet needs, and help ensure we’re solving urgent problems with a short path to value—not simply adding features. Who You Are A high-ownership PMM and builder who can go deep on a technical product and move quickly from 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 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 5–8+ years of 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 .
