Product Engineer

Location San Francisco Employment Type Full time Location Type On-site Department Engineering About Unlimited: Unlimited is an AI-native engineering and construction company reimagining how large-scale physical infrastructure gets built – from factories to power plants to entire industrial systems. We’re already delivering real projects with customers across multiple industries, using our AI-first engineering platform to design an order of magnitude faster than industry norms. Backed by some of Silicon Valley's top investors, we’re building a small, engineering-led team to scale what’s working and to take on one of the most important challenges of the coming decades. About the Role:We’re looking for talented electrical engineers who take ownership from initial design through construction. You’ll design and deliver the systems that power and control the physical world: substations, switchgear, transformers, MCCs, motor and drive systems, and the electrical integration of process and mechanical equipment across mining, critical minerals, power plants, data centers, and advanced manufacturing. This isn’t a traditional role. You’ll work within our AI-native engineering framework, using intelligent tools that learn from you as you work. Your engineering judgment and field experience will be encoded into the system itself, shaping how it designs and builds over time. The right person will see this as more than a faster way to engineer - it’s a chance to embed their knowledge into a system that scales their impact across every future project Unlimited builds. What You’ll Do: Lead design, integration, and commissioning for medium and low voltage power systems, including substations, switchgear, transformers, MCCs, cable routing, and grounding networks. Define and design electrical connections for motors, drives, instrumentation, and process equipment across full facilities. Develop one-lines, load flow and short-circuit studies, protection coordination, and equipment sizing for complex industrial systems. Work closely with controls, instrumentation, and mechanical teams to integrate power and control systems into complete plant designs. Participate in projects from early concept through field commissioning, validating automated design outputs against real-world conditions. Use and improve Unlimited’s AI-powered engineering tools to automate electrical design, simulation, and coordination. Support construction and start-up activities, resolving field issues and ensuring safe, reliable energization. Identify opportunities for standardization and modularization of electrical designs across projects. You Have: A strong foundation in electrical engineering, with experience designing, integrating, or commissioning power and control systems for factories, process plants, data centers, or other large industrial facilities. Expertise in one or more of: medium/high-voltage distribution, motor and drive systems, grounding, load flow analysis, or protection coordination. Experience integrating electrical with controls, instrumentation, and mechanical systems. Familiarity with electrical design tools (ETAP, SKM, EasyPower, Revit, or similar) and an interest in how these workflows can be automated or reimagined. Understanding of construction and commissioning environments, including field testing, energization, and safety practices. Curiosity about AI and how intelligent systems can extend engineering capability. Strong communication skills and the ability to collaborate across disciplines to solve cross-functional challenges. Comfort working under tight deadlines and ambiguity in a fast-paced, high-output environment. Ability to travel to customer sites and projects as needed. #J-18808-Ljbffr
