Working Hours/Days Position is exempt. Hours/days as needed. Overview Power the data centers, hospitals, and other mission-critical facilities of tomorrow—designing both rugged rental products and stationary generator-set packages that keep them online. As our Senior Electrical Project Engineer, you’ll work in a unique manufacturing and dealer environment, leveraging expert-level AutoCAD and Inventor skills to craft low- and medium-voltage AC layouts, DC controls, and the logic that ties multiple gensets into advanced paralleling switchgear and smart control panels. Juggle multiple high-impact projects, troubleshoot in the test cell, and serve as the go-to authority for production teams and customers alike—making an outsized impact alongside a collaborative squad of engineers, sales pros, and suppliers. Basic Duties + Develop exact electrical documentation + Produce comprehensive wiring schematics, conduit schedules, and panel layouts in AutoCAD and Inventor for diesel and natural gas gensets, ensuring every reference, layer, and legend is unambiguous. + Engineer control panel and breaker assemblies + Size and specify breakers, relays, PLC/HMI hardware, and interface circuits that integrate seamlessly with low to medium-voltage paralleling switchgear and DC control systems. + Verify compliance—line-by-line + Audit project drawings, vendor prints, and specifications against UL, NFPA 70/110, ISO, and customer standards; log variances and close them before release. + Provide data-driven field support + Diagnose elusive startup, commissioning, and controls problems for technicians through root-cause-based recommendations that feed back into design libraries to improve the product. + Serve as the technical reference for customers + Translate application questions into concise recommendations and solutions and document in formal engineering notes. + Maintain production continuity + Follow standard protocols and proven design protocols to ensure consistent high-quality products that meet or exceed customer requirements. + Manage the submittal dossier + Assemble, index, and track all drawings, studies, and data sheets through the approval cycle; document every revision for full traceability. + Leverage Caterpillar engineering resources + Retrieve and interpret factory application guides, PID data, and software updates; ensure the latest revisions are embedded in each project. + Enable precise estimating + Deliver dimensioned one-lines, BOMs, and labor take-offs to the Sales team so quotes reflect real scope, margin, and risk. + Design for the exceptional case + Apply first-principles analysis to bespoke components or control sequences required by unique site conditions or regulatory environments. + Control the critical path + Use tools and milestone checklists to keep engineering actions on time, document slippage causes, and propose corrective actions proactively. + Adapt as requirements evolve + When priorities shift, re-baseline drawings, calculations, designs, and priorities so the entire team works from a single source of truth. If precision, thorough documentation, and methodical problem-solving are how you create value, this role will let you practice your craft at a high level of electrical engineering discipline. Qualifications Education & Experience + B.S. in Electrical (preferred) — or at least ten years of hands-on experience in the engine-driven power-generation industry or a closely related technology field with design engineering experience for 5+ years. + Military veterans are strongly encouraged to apply.
