At Jacobs, we’re challenging today to reinvent tomorrow by solving the world’s most critical problems for thriving cities, resilient environments, mission‑critical outcomes, operational advancement, scientific discovery and cutting‑edge manufacturing, turning abstract ideas into realities that transform the world for good. electrical engineer with deep expertise in power systems modeling, rotating machinery, and electrical controls to join our digital twin and pre‑commissioning simulation practice . This mid‑level role targets a professional with 5–10 years of experience who brings rigorous electrical engineering fundamentals and the applied interest to translate that knowledge into high‑fidelity simulation models that de‑risk commissioning and validate design decisions before field equipment is energized. You will be a core technical contributor across a portfolio of digital twin and pre‑commissioning simulation engagements spanning data centers, distributed energy, advanced manufacturing, and other power‑intensive critical infrastructure.

Working within a multidisciplinary simulation team, you will develop and validate dynamic electrical models within physics‑based simulation platforms; design and execute scenarios covering contingency analysis, transfer and ride‑through validation, generation control logic, fault simulation, black‑start sequencing, and capacity analysis; and deliver technically rigorous outputs that translate simulation findings into actionable commissioning guidance.

Electrical Power Systems Modeling Dynamic Model
