Water Resources Engineer

At Riley Engineering, your work has a direct impact on the communities we serve. As a Native American-owned civil engineering firm specializing in water resources, we tackle complex challenges that affect public health, economic development, environmental stewardship, and access to essential infrastructure.

We're a team of problem-solvers who are passionate about engineering and committed to technical excellence. From day one, you will meaningfully contribute, work on diverse and challenging projects, and collaborate with leadership who value continuous learning and professional growth. 46% of our engineers have either a MS or PHD (or both) in civil engineering.

You’ll find more than a job at Riley, you’ll find purpose-driven work.

Candidate must demonstrate professional experience in an engineering consulting role. Resume must be project-based and include projects the candidate has worked on in the United States. Include: project title, client, location, your role, software you used, and any calculations or analyses you performed. Please do not apply if you do not meet these qualifications.

We are recruiting a talented and motivated civil engineer who is eager to grow with a dynamic and rapidly developing firm. This unique position will entail both field work and office-based engineering. The ideal candidate will feel energized conducting hands‑on field investigations, data collection, construction observations, and water/wastewater system assessments—while also excelling at technical analysis, design, modeling, and professional report writing.

If you enjoy contributing to water, wastewater, drainage, and site civil projects across sectors such as mining, residential, commercial, and tribal clients, this role may be the perfect fit.

Salary Range: $70,000 – $90,000, depending on qualifications and experience, based on a 40‑hour work week.

Office Responsibilities – Engineering & Technical Reporting

Water and Wastewater:

• Model and evaluate existing and proposed water distribution systems using EPANET, WaterCAD, Info Water, etc.
• Design long distance rural waterlines (alignment routing, plan and profile, pipe sizing, booster station design, tank design, pressure reducing valves, etc.)
• Design of sewer systems (sewer system extensions, septic systems, lagoons, etc.)
• Perform system planning, scenario analysis, and calibration
• Support preparation of permitting documents, engineering memos, and comprehensive technical reports
• Design of water and wastewater systems using AutoCAD Civil 3D

Hydrology and Hydraulics:

• Develop hydrologic and hydraulic models for the design and evaluation of stormwater control structures
• Perform hydrologic calculations using software such as HEC‑HMS, HEC‑SSP, HEC‑DSSVue, and GIS tools
• Conduct hydraulic analyses and flood studies using HEC‑RAS (1D/2D), Flow2D, Flow Master, HY‑8, Culvert Master, etc.
• Perform sediment transport analyses and evaluate impacts on stormwater structures
• Prepare detailed technical reports documenting methods, field data, modeling, and engineering conclusions
• Design of channels using AutoCAD Civil 3D

Site Civil Drainage and Design:

• Design stormwater and site civil infrastructure—retention/detention basins, grading, channels, riprap protection, drainage structures
• Develop AutoCAD Civil 3D drawings including grading plans, drainage systems, and wet utilities
• Prepare construction plans, specifications, and cost estimates

Field Responsibilities – Technical Field Engineer

• Travel to project sites within and outside typical work hours as needed
• Staking of long distance remote/rural waterline and sewer alignments
• Ground and drone reconnaissance of potential pipeline routes
• Perform flush testing of water distribution systems for hydraulic modeling and calibration
• Perform site visits, field investigations, and surveys to assess drainage patterns, channel conditions, erosion, sediment transport, and infrastructure performance
• Conduct field-based hydrology and hydraulics data collection (e.g., flow measurements, sediment sampling, GPS data collection, field reconnaissance)
• Inspect and oversee construction activities related to stormwater, site…
