Staff Frontend Engineer

Role details

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 Frontend Engineer at Circuit, you will be responsible for building high-quality, user-facing experiences in our core web application. You’ll work closely with Product, Design, and Engineering peers to turn product direction into intuitive, performant, and accessible interfaces. This role is highly collaborative and hands-on. You’ll contribute to frontend architecture and technical decision-making alongside other engineers, help set quality and engineering standards through example, and mentor teammates through code reviews and shared problem-solving. You’ll be expected to operate with autonomy, navigate ambiguity, and consistently deliver production-ready work that balances user experience, technical excellence, and business impact. We're also an agent-native engineering team. Engineers routinely run Claude Code and Cursor against our monorepo and we invest in the context, custom commands, and skills that make them effective. You should be excited to work this way: orchestrating agents for scoping, implementation, and triage, while owning the judgment, architecture, and quality bar yourself. Who Should Apply If you're a hands-on, staff-level frontend engineer who loves turning ambiguous product direction into enterprise-grade, production-ready interfaces, we'd love to hear from you. Equal Opportunity Employer We are an equal-opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
