Customer Marketing Manager

Product Marketing Manager, Customer References

At Port.io, we are building an open and flexible Agentic Engineering Platform for modern engineering organizations. Following our recent $100M Series C funding round, we are in a phase of rapid hypergrowth with strong enterprise momentum.

We act as the central nervous system for engineering, enabling platform teams to unify their stack and expose it as a governed layer through golden paths for developers and AI agents.

By combining rich engineering context, workflows, and actions, we help organizations transition from manual processes to autonomous, AI-assisted engineering workflows while maintaining control and accountability.

As a product-led company, we believe in building world-class platforms that fundamentally shape how modern engineering organizations operate.

Port is growing fast, and we're looking for a Product Marketing Manager, Customer References to build the engine that turns customer success into Port's most powerful go-to-market asset.

You are passionate about customer storytelling and thrive in ambiguity. You know how to identify the right customer voices, build trust with senior stakeholders, and translate complex technical outcomes — reduced onboarding time, faster provisioning, improved developer experience — into narratives that resonate with engineering leaders and platform teams. Reporting to the Head of Product Marketing, you'll own Port's customer reference and advocacy program end-to-end, producing the proof points that accelerate deals, build market credibility, and demonstrate the real-world value of Port's platform.

What You'll Do

Customer Reference Program

• Build and scale Port's customer reference program, including a structured database of referenceable customers, advocates, and proof points segmented by use case, industry, company size, and persona
• Partner with Sales and Customer Success to identify and cultivate customer champions at strategic accounts
• Develop tiered reference tracks — reference calls, case studies, event speakers, advisory participation — matched to sales stage and buyer need

Storytelling & Content

• Lead production of high-impact customer content: written case studies, video testimonials, one-pagers, ROI spotlights, blog posts, webinars, social proof snippets, and more.
• Interview customers and translate technical outcomes into compelling narratives for engineering leaders, platform teams, DevOps practitioners, and executive stakeholders
• Maintain a library of use-case-specific proof points that Sales, SDRs, and Product Marketing can pull from at any stage of the funnel

Sales Enablement

• Equip Sales and SDR teams with reference assets tailored to deal stage, vertical, use case, and objection type
• Integrate customer evidence into core messaging, pitch decks, and competitive materials
• Track asset usage and sales feedback to continuously improve content quality and relevance

Customer Advocacy & Engagement

• Strategically recruit, nurture, and manage customer advocates, maintaining an ongoing engagement cadence
• Coordinate customer participation in webinars, conferences, press opportunities, and Port-hosted events — from sourcing to speaker prep and execution
• Collaborate on high-impact customer programs including the Customer Advisory Board (CAB), Customer Summit, and other strategic customer-facing initiatives — contributing to agenda development, customer recruitment, and content that reflects the voice of the customer
• Serve as a trusted advisor to cross-functional teams on how to leverage customer stories for maximum impact

Customer Data & Market Intelligence

• Own Port's anonymized customer usage data as a strategic asset — analyzing customer cohorts, use cases, product usage patterns, surveys, and behavioral signals
• Distill data streams into compelling storytelling: infographics, benchmark reports, and other collateral for thought leadership, awareness campaigns, and sales proof points
• Partner with Product, Data, and Demand Generation teams to identify and package the most impactful insights for external audiences

Measurement & Optimization

• Define and track KPIs for the reference program's health

Requirements

• 5+ years of experience in customer marketing, product marketing, or a related B2B marketing role
• Proven experience building or scaling a customer reference or advocacy program
• Strong storytelling instincts with excellent written and verbal communication skills — you know how to draw a compelling narrative out of a technical customer conversation
• Technical curiosity and comfort learning complex products; familiarity with developer tools, DevOps, platform engineering, or cloud infrastructure is a strong advantage
• Demonstrated ability to build relationships with enterprise customers, from practitioners to executive leaders
• Highly organized, self-directed, and effective in fast-moving, cross-functional environments

Nice to Have

• Experience marketing developer tools, internal developer platforms (IDPs), DevOps platforms, or infrastructure tooling
• Familiarity with reference management or CRM tools (e.g., HubSpot, ReferenceEdge, Influitive)
• Experience supporting high-touch executive or customer marketing programs
• Comfort presenting to both deeply technical audiences and executive stakeholders

Why Port

• Build something from the ground up at a company in hypergrowth
• Work with a product that engineering teams genuinely love — and customers who are excited to share their stories
• High-visibility role with direct impact on revenue and brand
• Collaborative, low-ego culture with strong cross-functional support
