Senior Product Marketing Manager

About Circuit Circuit is the AI execution layer for the physical economy. Industrial and manufacturing enterprises run on expertise: the hard-won knowledge of how complex products are engineered, configured, sold, and supported. That expertise is scarce, slow to transfer, and walking out the door as a generation of experts retires. It lives in PDFs, spreadsheets, and the heads of a few people, and the hardest technical decisions wait on whoever happens to know. Circuit puts expert judgment in everyone's hands. We capture how the best people make critical technical decisions and turn it into agents that do the judgment-heavy work, so anyone, regardless of skill level, can make the right call, from quote to install and support, with the accuracy these environments demand. Circuit is built by operators. Our leadership team has built and scaled real industrial companies, and we are already live in production with category-leading manufacturers. We are not bolting AI onto an old playbook. We are building the layer that runs the last mile of how the physical economy executes. The Role As Sr. Product Marketing Manager at Circuit, you'll help shape how our products are positioned, launched, and sold. You'll own messaging for Circuit's core use cases, run the launch motion that carries each release into the market, and arm Sales and Customer Success with the positioning, tools, and proof they need to win. This is an individual contributor role with real ownership. You'll run positioning and messaging for your areas end to end, from customer and competitive research through launch, enablement, and web. You'll partner with Product on how we talk about what we build, and with Sales and CS to make sure that story lands in every deal. This is a builder role. You'll help establish the launch framework, enablement system, and measurement for product marketing at Circuit while staying deeply hands-on with execution. Because marketing at Circuit is still taking shape, you'll also take on broader marketing work as needed, including social, content, and executive ghostwriting.
