  • Design stormwater best management practices (e.g., infiltration basins, bioretention areas, filters) in accordance with agency requirements
  • Prepare and oversee development of design documentation including drawings and technical specifications (with ability to directly assist as required)
  • Provide senior review of engineering calculation briefs, design reports, design drawings, technical specifications, and permitting submittals
  • Provide office-based construction support, including providing contractor assistance (e.g., responding to RFIs), technical submittal review, and implementing real-time design changes based on conditions encountered in the field
  • Present on technical and engineering topics to clients and regulatory agencies
  • Work with senior staff in client development activities, including proposal writing, estimating project costs, client presentations, and periodically attending industry professional conferences
  • Mentor and delegate to junior team members
