• Engineer-in-Training (EIT) certification; Professional Engineer (P.E.) license in California preferred, or ability to obtain California licensure by comity/reciprocity when eligible.

• At least 5 years (7+ years preferred) of related stormwater, water resources, civil/environmental engineering, or watershed planning experience; or equivalent combination of education and experience. (required)
• Experience supporting stormwater feasibility studies, conceptual design, BMP siting/prioritization, green infrastructure or LID planning, stormwater capture/diversion projects, watershed planning, and/or water quality improvement programs. (required)
• Proficiency with hydrologic and hydraulic modeling/design tools such as SWMM/PCSWMM, HEC-HMS, HEC-RAS, MODRAT, SBPAT, WMMS/LSPC, or similar platforms. (required)
• Working knowledge of California municipal stormwater programs, MS4/NPDES permit requirements, TMDLs, WQIPs/EWMPs, RAAs, SWPPPs, monitoring plans, and Regional Water Quality Control Board processes. (preferred)
• Strong GIS, data analysis, technical writing, engineering judgment, task coordination, and communication skills, including the ability to translate complex technical findings for technical and non-technical audiences. (required)
• Experience preparing feasibility reports, technical memoranda, conceptual design documents, cost estimates, funding-support materials, permit-support documents, and client presentations. (required)
• Experience coordinating with municipalities, county agencies, regulators, transportation agencies, water/wastewater agencies, community organizations, and interdisciplinary teams. (preferred)
• Experience serving as a task lead, deputy project manager, or technical lead, including coordination of deliverables, budgets, schedules, QA/QC reviews, stakeholder input, and junior staff support. (preferred)
• Familiarity with Southern California stormwater funding programs, multi-benefit project prioritization, public engagement, climate resilience planning, and equity-focused water resources planning. (preferred)
• Ability to succeed in a fast-paced consulting environment, manage multiple priorities, meet deadlines, and travel to project sites or client facilities as needed. (required)
• Health & Safety training, medical monitoring, and client-driven drug and background testing may be required.
• Valid U.S. driver27s license and a satisfactory driving record for business travel. (required)
