Position Overview

We are seeking a Civil Engineer II who will be an independent contributor responsible for civil design packages across the full project lifecycle. This role requires experience with utility-scale solar or energy infrastructure, proficiency in our design toolset, and the ability to coordinate with other disciplines.

What You’ll Do

  • Civil & Site Design Lead preparation of complete civil site design packages: grading plans, drainage reports, erosion and sediment control (SWPPP), access road design, and site layout for utility-scale solar facilities (ranging from 5 to 500+ MW AC).
  • Develop and QC Civil 3D models, including corridor modeling, surface development, alignment design, and earthwork optimization to minimize cut/fill imbalance across large-scale sites.
  • Coordinate with hydrological and hydraulic analysis for stormwater management including pre/post runoff comparisons, detention/retention basin sizing, and floodplain coordination.
  • Design access roads and internal haul routes to accommodate heavy equipment loads (crane pads, transformer delivery routes) per geotechnical recommendations.
  • Prepare and review construction documents for permit submission to AHJs, state environmental agencies, and utility interconnection authorities.
  • Project Coordination & Delivery
    • Serve as lead civil/structural engineer of record (or EOR designee) on assigned projects, managing design deliverables from 30% through IFC (Issued for Construction).
    • Coordinate with civil, environmental, electrical, and structural disciplines as well as external consultants, surveyors, and geotechnical firms.
    • Support client-facing meetings and agency pre-application conferences; prepare and present technical content to clients and permitting authorities.
    • Review and respond to RFIs, design change requests, and contractor submittals during construction phase.
    • Manage project files, CAD standards, and QA/QC checklists to ensure deliverable consistency across the team.
  • Internal Contribution
    • Mentor Engineer I staff and designers on design methodology, software use, and project workflow.
    • Contribute to the development and refinement of CAD/engineering SOPs, design templates, and calculation workbooks.
    • Identify process inefficiencies and propose improvements to project delivery workflows.

What You Bring

  • Bachelor's degree in Civil Engineering or Environmental Engineering.
  • 3–5 years of experience in civil site design, with at least 2 years on utility-scale solar or energy infrastructure projects.
  • PE licensure (or active EIT with clear path to PE within 12 months strongly preferred).
  • Advanced proficiency in AutoCAD Civil 3D (grading, corridors, surfaces, alignments, profiles, cross sections, volumes).
  • Experience with PVCase or comparable solar layout tools for panel layout optimization and civil integration.
  • Demonstrated experience preparing stormwater reports, SWPPPs, and drainage design for large impervious surface projects.
  • Ability to read and interpret geotechnical investigation reports and apply findings to civil and structural design.
  • Familiarity with NEPA, state environmental permitting, stormwater general permits (CGP), and county-level land development processes.
  • Strong technical writing skills; experience preparing engineering reports and permit applications.
  • Experience with utility interconnection submittals and coordination with transmission/distribution owners preferred.
  • GIS proficiency (ArcGIS or QGIS) for site suitability analysis and constraint mapping preferred.
  • Familiarity with battery energy storage system (BESS) site design and applicable fire/life-safety codes (NFPA 855) preferred.
  • Experience with AHJ coordination in Florida and/or multi-state project portfolios preferred.
