Product Marketing Manager

Sent is a developer tool for customer engagement. We help developers and agents deliver messages across voice, SMS, WhatsApp, and RCS through a single API. Our intelligent routing model automates channel selection, ensuring lower cost and global deliverability without channel-specific integrations. Our built-in multitenancy also enables our customers to deploy messaging and voice agents across their own customers.

We recently closed a $12M Series A backed by Companyon Ventures, Bessemer Venture Partners, UIF, and others. We're hiring the best to scale a best-in-class platform.

The Role

We're hiring a Product Marketing Manager to own how Sent's products are positioned, launched, and brought to the developer market. You'll translate complex communications infrastructure into clear, differentiated messaging that resonates with developers, engineering leaders, and software platforms deploying customer-facing agents across their users.

This is a deeply technical, hands-on role. You'll understand our products at the API and architecture level, independently explore and test technical capabilities, and create credible content for developer audiences. You'll work closely with Product, Engineering, DevRel, Growth, and Sales to drive launches, developer adoption, and platform expansion.

What you'll do

• Own product positioning, messaging, launches, and GTM strategy across Sent's agent infrastructure, messaging, and voice products.

• Develop differentiated technical narratives for developers, engineering leaders, and platforms deploying agents across multiple businesses.

• Lead product launches end-to-end, from defining target audiences and use cases to creating content, coordinating distribution, and driving adoption.

• Communicate Sent's technical differentiation across agent execution, tool integrations, customer context, communications infrastructure, and deployment models.

• Lead developer research, win/loss analysis, and competitive intelligence to inform positioning, product strategy, pricing, and packaging.

• Hands-on experience with developer products and a strong understanding of how developers evaluate, integrate, and deploy technical infrastructure.

• History owning technical product positioning, launches, and GTM execution with measurable results.

• Exceptional technical writing skills, with the ability to create accurate, compelling developer-facing content independently.

• Strong understanding of APIs, integrations, deployment models, and build-vs-buy decisions.

• A resourceful, execution-oriented approach to independently researching, creating, testing, and shipping high-quality work.

• Experience conducting developer research, competitive analysis, and creating technical sales enablement materials.

• Demonstrated proficiency using AI tools to improve the speed and quality of your work.
