Electrical Engineer, Digital Twin & Simulation

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.

We are seeking an experienced E
lectrical 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 an 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 Development – Build physics‑based dynamic models spanning the full power path—from utility supply or on‑site generation through switch gear and distribution to load endpoints. Represent key equipment characteristics including rotational inertia, governor type and response, droop control, alternator winding parameters, ATS transfer timing, UPS topology and bypass logic, and branch circuit coordination.

Rotating Machinery & Generation – Develop models of reciprocating engine‑generators, combustion turbines, and hybrid generation configurations. Accurately represent governor and AVR behavior, paralleling switch gear synchronization, load‑sharing characteristics, and generation source interactions during paralleling, load transfer, and unit trip events. Model BESS grid‑forming and frequency/voltage response behavior where applicable.

Transient, Harmonic & Protection Analysis – Model transients and power quality phenomena including voltage and frequency deviation during transfer events, RoCoF under generation loss, THD under non‑linear loading, and UPS waveform degradation during fault events. Model protection relay coordination, overcurrent device selectivity, and breaker trip/reclose logic. Evaluate outputs against applicable standards including ITIC/CBEMA and IEEE 519.

• Contingency & Fault Simulation – Develop and execute N‑1/N‑2 contingency scenarios, ATS open‑ and closed‑transition transfer scenarios, and UPS power path fault scenarios. Assess power margin, overload duration, waveform quality, ride‑through behavior, and load transfer success against defined acceptance criteria. Design cascading multi‑system fault scenarios to evaluate failure behavior, alarm escalation logic, and load shedding sequences.
• Black‑Start Sequencing – Model and execute complete startup from de‑energized conditions, sequencing generation ignition, governor stabilization, switch gear closure with synchronization verification, UPS initialization, and load energization. Identify automation gaps, validate interlock release logic, and document the full sequence timeline from de‑energized conditions to stable generation and load acceptance.
• Capacity & Expansion Envelope Analysis – Model phased expansion scenarios to evaluate whether planned electrical infrastructure can support incremental load additions with acceptable redundancy margins. Produce headroom analyses, uptime projections, and fuel‑limited runtime assessments to support…
