About OpenRouter OpenRouter is the AI routing and infrastructure layer that AI builders, AI-native startups and enterprises use to access, manage, and optimize the AI usage across their business, through a unified API, billing interface, and analytics platform. We power some of the most advanced AI builders in the world by giving them the flexibility to move fast, scale confidently, and stay future-proof as models evolve.

As enterprise adoption of AI accelerates, OpenRouter sits at the center of how organizations operationalize LLMs across research, product, and production workloads.

The Role We're looking for a Founding Product Marketer who will serve as editor-in-chief for all external developer messaging while building the systems and orchestrating the execution that transforms how OpenRouter communicates with developers and customers. This is an IC PMM role with significant Founder and leadership exposure, at the intersection of product marketing and content creation. You ensure that every piece of content that leaves OpenRouter is technically accurate, strategically aligned, and resonates with technical audiences.

You will own the strategy and execution for product launches, model releases, feature announcements, and thought leadership. You'll create the templates, positioning frameworks, and processes that enable founders, engineers, and other builders to communicate authentically and consistently across social media, blog posts, and community channels. This role is about systematizing what works and building the messaging infrastructure that amplifies OpenRouter's technical authority through education, and accessible developer on-ramps.

You will use AI extensively to draft, edit, and prototype content and must have demonstrated experience using AI tools and agents as a part of a high-velocity communications calendar.

What You'll Do

• Serve as Editor-in-Chief: Own editorial quality for all external content—ensuring clarity, consistency, technical accuracy, and strategic alignment across everything OpenRouter publishes.
• Orchestrate and Systematize Content Strategy: Coordinate and enable internal builders and executives to communicate effectively, ensuring coverage of key product launches and a cohesive point of view across all channels.
• Own Product Launch Narratives: Develop positioning and messaging for new features, model integrations, and product releases that establish technical authority and differentiation.
• Build AI-Native Content Systems: Design and manage the "system prompts" for AI-assisted content creation—establishing guardrails, quality standards, and brand guidelines that enable scalable, high-quality output.
• Enable Founder-Led Marketing: Support executives with ghostwriting, content strategy, and messaging guidance for personal accounts on Twitter, LinkedIn, and other platforms.

What We're Looking For

• 5-7 years in product marketing or developer marketing, ideally at a technical platform, API-first company, or developer tool.
• Strong technical fluency with API products, developer workflows, and the ability to understand and communicate complex technical concepts clearly.
• Exceptional writing and editing skills with demonstrated ability to create compelling content across formats (blog posts, social media, web copy, positioning documents).

Nice to Have

• Prior experience in AI/ML, LLM ecosystems, or developer infrastructure products.
• Track record launching technical products or features with strong content-led strategies.
• Experience building and managing content systems, style guides, and brand voice frameworks.
• Strong social media presence or demonstrated ability to create viral, engaging technical content.
• Familiarity with developer communities, technical Twitter, and how developers discover and evaluate infrastructure tools.

Why OpenRouter

• Work at the center of the AI infrastructure stack as enterprises define how they adopt LLMs.
• Build the content and positioning strategy for a product with clear, tangible ROI: cost efficiency, scalability, flexibility, and innovation velocity.
• High ownership and visibility with direct impact on how OpenRouter is perceived in the market.
• Competitive compensation, including base salary and equity.
• Fully remote team with a strong culture of autonomy and trust.
