Civil Engineer (Hydrology and Hydraulics)

Location: Remote, USA; ideally based in the San Francisco, Long Beach, or Houston offices, with full-time onsite expectations except for bi-weekly WFH Fridays. Exceptions may be considered for exceptional candidates outside these hubs.

Company

hirify.global develops data center and energy infrastructure projects.

What you will do

• Evaluate prospective sites using survey, terrain, watershed, and floodplain information, identifying drainage constraints and impacts on development cost, schedule, and usable area.
• Develop and review hydrology and hydraulic models using HEC-HMS, HEC-RAS, including 1D and 2D analysis where appropriate.
• Design stormwater conveyance and detention systems, erosion protection, post-construction water-quality measures, and low-impact development BMPs where required.
• Prepare erosion and sediment control plans, support SWPPP preparation and compliance, and develop drainage reports, calculations, specifications, exhibits, and Civil 3D plan sheets.
• Establish flood-protection criteria for critical facilities and integrate drainage with grading, building pads, retaining walls, utilities, and access roads.
• Coordinate permitting and technical reviews, support FEMA-related submittals, review consultant deliverables, resolve agency comments, and assist with RFIs, field observations, as-builts, certifications, and operation and maintenance plans.

Requirements

• Bachelor’s degree in Civil Engineering or Water Resources Engineering from an ABET-accredited program.
• 5+ years of relevant civil engineering experience, including at least 3 years of hands-on experience in hydrology, hydraulics, drainage design, or floodplain analysis.
• Demonstrated proficiency in HEC-RAS and HEC-HMS, including model development, interpretation, and documentation, plus culvert and storm sewer analysis tools such as HY-8, Storm and Sanitary Analysis, StormCAD, or equivalent.
• Proficiency in AutoCAD Civil 3D for grading, drainage layouts, profiles, and construction plan production.
• Experience designing detention and conveyance systems and preparing drainage reports for agency review.
• Working knowledge of FEMA floodplain information, local stormwater and floodplain development criteria, NOAA Atlas 14 rainfall data, and standard hydrologic methods including Rational, NRCS/TR-55, and unit hydrograph methods.
• Ability to manage multiple project priorities, explain technical tradeoffs clearly, and coordinate effectively with design and construction teams.

Nice to have

• Professional Engineer licensure, particularly in Texas or Oklahoma, or a clear path to obtaining licensure.
• Experience with HEC-RAS 2D, ArcGIS or QGIS, and stormwater platforms such as SWMM or HydroCAD.
• Master’s degree focused on water resources, hydrology, or hydraulic engineering.
• Experience supporting no-rise certifications, CLOMR/LOMR applications, and floodway or floodplain crossing analyses.
• Experience with USACE Section 404 crossings, construction stormwater permitting, or state dam safety review of large detention facilities.
• Background in data centers, substations, industrial facilities, or other large sites with critical infrastructure.
• Experience carrying designs from feasibility through construction and improving reusable models, templates, and design standards.

Culture & Benefits

• Work closely with civil engineers, project development teams, construction managers, external consultants, permitting agencies, surveyors, geotechnical engineers, and environmental consultants.
• Hybrid arrangement with full-time onsite work at a hub office and bi-weekly work-from-home Fridays.
• Potential flexibility for exceptional candidates living outside the listed office hubs.
