Staff Product Engineer

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 a Staff Applied ML Engineer, you are responsible for turning ML capabilities into production-ready product features.

This is a hands-on IC role with high ownership. You are accountable for ML-driven features working end to end. That includes how models, retrieval systems, and agent workflows come together, how they behave in real usage, and whether they meet customer expectations.

You will work side by side with our ML experts, taking ideas and novel approaches and driving them into reliable, production-ready systems that are integrated, tested, and behaving correctly within the full product.

You should be comfortable moving quickly to prototype and validate ideas, while also bringing the engineering discipline needed to build reliable, testable, and maintainable systems. A core part of the role is improving the quality of the ML codebase over time without slowing down iteration.

AI coding tools are core to how you work every day. You use them fluently to explore, build, and test, and you have the judgment to evaluate what they produce. We ship fast and we ship with quality.
