Hydraulics Engineer

Design a career and build your future… Because it matters! Geomorphology Eco/Hydraulics Analyst McMillen Inc. is looking for a Geomorphology Eco/Hydraulics Analyst with 3+ years of experience to support projects across California’s diverse hydroclimates. This role offers the opportunity to apply hydraulic and geomorphic analysis to real-world challenges in habitat connectivity, sediment management, and climate resilience. Responsibilities: Conduct eco-hydraulic analyses linking flow, sediment, and habitat conditions to species requirements across diverse California hydroclimates. Assist in developing and calibrating 2D hydraulic and habitat models (e.g., HEC‑RAS 2D, SRH-2D, or IFIM-based frameworks) to assess flow‑ecology relationships, sediment mobility, and thermal regimes. Contribute to sediment continuity and geomorphic response analyses downstream of dams, diversions, wildfire burn areas, and restoration corridors. Support integration of climate resilience and post-fire hydrology into modeling and watershed assessments, including evaluation of Forecast‑Informed Reservoir Operations (FIRO), drought adaptation, and floodplain reconnection strategies. Prepare figures, technical memoranda, and report sections supporting environmental flow, sediment management, and habitat connectivity studies. Collaborate closely with engineers, biologists, and planners on interdisciplinary project teams to interpret results and develop actionable recommendations. Support stakeholder communication and regulatory engagement through clear data visualization, concise technical writing, and presentation of model results. Qualifications: Minimum of 3 years of professional experience in eco‑hydraulics, fluvial geomorphology, or water resources engineering. Bachelor’s degree in Geoscience, Engineering, Environmental Science, or related field required; Master’s degree preferred (Eco‑Hydraulics, Fluvial Processes, or Fisheries Habitat Modeling focus). Strong understanding of hydrologic, hydraulic, and geomorphic processes influencing river and watershed systems. Experience with 1D/2D hydraulic or habitat modeling tools such as HEC‑RAS 2D, SRH‑2D, RiverFlow2D, or similar frameworks. Familiarity with sediment transport analysis, channel morphology assessment, and environmental flow evaluation. Proficiency in GIS‑based terrain and spatial analysis (ArcGIS Pro or QGIS). Experience with data processing and visualization tools; Python or R skills preferred. Strong technical writing and data presentation abilities, including preparation of figures, memos, and report sections. Ability to collaborate effectively within multidisciplinary teams and communicate results to technical and non‑technical audiences. Compensation Package: Pay Range: $35 hr. – $46 hr.
