About The Position

Cummings Electrical is hiring an Electrical Designer III for our Integrated Manufacturing facility in Arlington, TX. Cummings Electrical is expanding our Integrated Manufacturing team. We design and build custom, integrated, modular systems such as e-houses, electrical skids, HAC’s and UL 508A panels for a wide range of projects, including data centers, healthcare facilities, industrial plants, and more. As part of our team, you will work hands-on in a fast-paced, innovative environment, helping reduce jobsite risks, accelerate project timelines, and deliver high-quality solutions. If you are looking for growth, meaningful work, and a chance to be part of a team shaping the future of off-site integration and manufacturing, this is the place to make an impact.

Requirements

5 to 7 years of progressive electrical infrastructure design experience, heavily concentrated within the data center, telecom, or heavy industrial sectors.
Master-level application of the NEC, Uptime Institute guidelines, and IEEE standards.
Bachelor's degree in Electrical Engineering preferred; EIT or PE track status is a major differentiator.

Responsibilities

Architect comprehensive power infrastructure strategies for hyperscale facilities, ensuring resilience, concurrent maintainability, and code compliance.
Execute and sign off on advanced calculations including breaker setting profiles, short circuit thresholds, and feeder physical dimension parameters.
Enforce strict adherence to the National Electrical Code (NEC - Article 645), NFPA 70E, and local regulatory mandates.
Manage the end-to-end development of comprehensive contract documents, single-line topologies, load calculation structures, and specifications.
Provide direct mentoring, technical review, and professional validation of work created by Level I Designers and Level III Modelers.
Lead the complete engineering design of medium-to-low voltage distributions, substations, generator configurations, UPS systems, and mission-critical topologies (e.g., 2N, Block Redundant).
Direct modeling strategies, review spatial distributions for compliance, and use BIM environments to evaluate electrical system integrity.
Mastery of fault current calculations, discrimination coordination, arc flash safety boundary logic, lightning mitigation, and mission-critical reliability matrices.
Approve and sign off on full structural contract documents, single-lines, schematic sequences of operations, and comprehensive building plans.
