Product Marketing Manager; Technical​/AI Infrastructure

Product Marketing Manager (Technical / AI Infrastructure)

Subquadratic Inc. – San Francisco, CA, United States

Subquadratic (SubQ) is an AI infrastructure and research company building a new class of LLMs on a proprietary post-transformer architecture. While the major labs focus on incremental transformer improvements, we’re pursuing foundational change at the model architecture layer — enabling large-context, multimodal inference that scales efficiently where traditional transformers break down.

Our models are designed for long-context reasoning, persistent memory, agentic systems, and large-scale multimodal workloads. We’re building core infrastructure for the next generation of AI systems.

SubQ is hiring a Product Marketing Manager to help define how the market understands our technology, products, and long-term vision. This is not a traditional B2B SaaS product marketing role. We are looking for someone who deeply understands the AI/ML and developer infrastructure ecosystem and can translate highly technical concepts into compelling narratives, positioning, and messaging for sophisticated technical audiences.

You will own core product messaging and positioning across the company, helping shape how developers, researchers, founders, and enterprise technical buyers understand SubQ’s architecture, capabilities, and differentiation. This role sits at the intersection of product, research, engineering, GTM, and content.

The ideal candidate combines strong strategic thinking with exceptional technical storytelling and copywriting skills. You should already be familiar with the AI infrastructure landscape and have experience positioning complex technical products within fast-moving markets. You’ll work closely with leadership, engineering, research, and marketing to drive product launches, messaging strategy, technical GTM initiatives, and category-defining narratives that help establish SubQ as a leader in next-generation AI infrastructure.

Develop and refine SubQ’s core messaging, positioning, narrative, and category strategy across products, research initiatives, and GTM efforts.

Work closely with researchers and engineers to deeply understand complex AI infrastructure concepts and turn them into clear, credible, and differentiated messaging for technical audiences.

Lead messaging and GTM support for product launches, benchmark releases, research announcements, demos, and technical campaigns.

Help define how SubQ communicates its long-term vision, technical differentiation, and market positioning within the broader AI ecosystem.

Collaborate cross-functionally with engineering, research, leadership, recruiting, GTM, and content teams to ensure consistency and clarity across all external communication.

Partner with leadership on high-impact thought leadership, technical commentary, social content, conference materials, and strategic communications.

Track trends across AI/ML, LLMs, inference, agents, long-context systems, developer tooling, open-source ecosystems, and frontier AI research to inform positioning and messaging strategy.

Help shape developer-facing and technical GTM initiatives including launch strategy, content strategy, competitive positioning, and ecosystem engagement.
