Job description

Timmons Group is seeking a Senior Electrical Designer to join our Energy team supporting utility-scale solar photovoltaic (PV) and Battery Energy Storage System (BESS) projects. The successful candidate will provide electrical drafting and design support throughout conceptual, preliminary, and final design. This position will work closely with project engineers and project managers to develop complete and coordinated design packages for renewable energy projects. Essential Duties and Responsibilities include, but are not limited to: • Develop electrical design drawings for utility-scale PV and BESS projects using AutoCAD. • Prepare and revise electrical site plans, equipment layouts, one-line diagrams, wiring diagrams, grounding plans, underground conduit and cable plans, and installation details. • Develop medium-voltage collector system layouts, including equipment locations, underground cable routing, trenching, conduit requirements, and overhead medium-voltage collection and interconnection lines. • Develop overhead medium-voltage line layouts, including pole locations, conductor routing, line crossings, equipment locations, and transitions between overhead and underground systems. • Prepare plans, profiles, details, material schedules, and other design documentation for overhead and underground medium-voltage systems. • Develop BESS equipment layouts and electrical interconnections, including batteries, inverters/power conversion systems (PCS), transformers, switchgear, and other balance-of-system equipment. • Develop PV electrical layouts including inverter locations, medium-voltage equipment, DC collection systems, and AC collection systems. • Prepare equipment schedules, cable schedules, bills of materials, construction details, and other project deliverables. • Coordinate electrical drawings with civil, structural, substation, SCADA, and other project disciplines. • Coordinate overhead medium-voltage designs with civil/site layouts, access roads, utilities, environmental constraints, and other project infrastructure. • Incorporate engineering calculations, equipment vendor information, client standards, markups, sketches, and engineering direction into design documents. • Assist with development of issued-for-construction drawing packages. • Review drawings for accuracy, consistency, constructability, and compliance with project standards. • Work independently on design assignments while coordinating closely with the project engineer and project manager. • Assist with CADD standards, drawing organization, and mentoring less-experienced designers and CADD users. Essential Duties and Responsibilities include, but are not limited to: • Associate degree or technical certificate in computer-aided drafting/design, engineering technology, or a related field, or equivalent relevant experience. • Minimum of five years of electrical drafting/design experience, preferably involving utility-scale solar, BESS, power generation, substations, or other power-delivery projects. • Proficiency with AutoCAD and experience developing multi-sheet electrical construction drawing packages. • Working knowledge of electrical equipment, conduit and cable routing, grounding, and medium-voltage electrical systems. • Ability to interpret electrical one-line diagrams, engineering markups, equipment drawings, and vendor documentation. • Strong attention to detail and organizational skills. • Ability to manage multiple design assignments and work effectively both independently and as part of a multidisciplinary project team. • Strong verbal and written communication skills. Preferred Qualifications • Direct experience designing utility-scale solar PV and/or BESS facilities. • Experience with 34.5 kV or similar medium-voltage collector systems. • Experience with overhead medium-voltage distribution or collector systems, including pole layouts, conductor routing, line crossings, and overhead-to-underground transitions. • Familiarity with overhead line design considerations including clearances, pole loading, guying, conductor selection, and utility design standards. • Experience developing IFC-level renewable energy drawing packages. • Familiarity with PV inverters, BESS PCS equipment, medium-voltage transformers, switchgear, collection systems, and equipment vendor drawings. • Experience coordinating electrical designs with civil/site design and substation/interconnection design. • AutoCAD Civil 3D, MicroStation, or other relevant design software experience is a plus. The requirements listed are representative of the knowledge, skills and/or abilities required.
